Total grinding costs are lower with CF&I grinding

balls and rods

Grinding Balls and Hods have a direct bearing on major grinding costs — mill throughput and power consumption. The use of CF&I Grinding Balls and Rods will actually increase your mill throughput, lowering power consumption per ton of material ground. This is a result of the microstructure of the high quality steel made and used by CF&I.

CF&I Grinding Balls have the balance of hardness and toughness that provides proper wear and impact resistance. In addition, their

excellent abrasion resistance permits them to wear evenly and retain their original shape.

CF&I Grinding Rods—through controlled mill chemistry techniques — have excellent wearing properties, resisting bending and premature breakage.

Al l these factors contribute to more efficient grinding, higher throughput... lower grinding costs. For the complete story on the advantages of CF&I Grinding Balls and Rods, contact your local CF&I sales office.

NEWS OF THE MINERAL INDUSTRIES Poul Weir Investigates Coalbrook Mine Disaster

Paul W e i r , chairman of the Board of the Paul W e i r Co . , Inc., Chicago, returned M a r c h 25, from a unique technical mission to Coalbrook, O r ange Free State, South A f r i c a , scene of the disaster which occurred on January 21, 1960 and which claimed the lives of 436 miners.

M r . W e i r was engaged by the owners, the Clydesdale Collieries Limited, to join Sir A n d r e w Bryan, British coal mining authority, to investigate

probable causes and to make recommendations. ^ , ;

T h e two experts agreed that the disaster at tbeV N o r t h Coll iery was caused by an iunprecedented fracture of the overlying strata, resulting in the collapse of an area of mine workings approximately 1,000 acres in extent. T h i s colliery was developed 50 years ago and has operated continuously. N o disaster of a similar nature has ever occurred in this coal field.

M r . W e i r is the only living A m e r i can honoi"ary member of the Uni ted King4!^m's Institution of M i n i n g E n gineer. Sir A n d r e w is also an honorary.member. M r . W e i r is past chairman of the C o a l Division of the American Institute of M i n i n g and Metal lurgical E n g i n e e r s , and an Erskine Ramsay gold medallist.

World Market for Tungsten To Increase Throughout 1960

Minerals Engineering C o . president R . G . Sullivan believes the "world market for tungsten wi l l increase steadily throughout 1960 as tungsten is becoming increasingly im

portant in high temperature alloys

for missiles, rockets, and jets."

Sullivan said recently the developrnent of high temperature alloys has also been responsible for increased interest in metallic compounds that are resistant to high temperatures. H e cited such products as electric-furnace abrasives which include tungsten carbide and new cemented carbides which are now used extensively in jet engines, rocket motors, and atomic energy plants.

A s a part of the company's expansion program, Sullivan also reported that the program for vanadium production has "sustained earlier predictions." H e said the company now expects to build additional facilities adjacent to its Salt Lake Ci ty tungsten plant within two months and expects to be in fu l l production of vanadium during the fourth quarter. T h e new Salt Lake Ci ty facilities, Sullivan said, w i l l be constructed to produce "vanadium pentoxide" from the byproduct vanadium.

New features mean easier setups,

faster drilling - and extra stamina

f e a t u r e s

5-POSITION THROTTLE

a d v a n t a g e s

All drilling functions are on one convenient control — blowing, feeding, collaring, drilling. In feeding position, feed-leg pressure is adjusted by a roll-type valve on drill handle.

INTEGRAL FEED LEG WITH ADJUSTABLE TENSION & BALANCE

STOPER-TYPE FRONTHEAD CONSTRUCTION

Only one air hose connection needed — air from drill casing passes to the leg through built-in connection. Tension on knee joint and balance of drill on leg both adjustable to suit operator's preference.

Fronthead fits into deep counterbore in cylinder, providing extra strength and rigidity that means longer trouble-free performance in feed-leg drilling.

TELESCOPIC FEED LEG Telescoping leg extends from 55" to 127"—provides greater feeding pressure on high back holes without auxiliary extensions.

SPOOL TYPE DOUBLE KICKER PORT VALVE

RETRACTABLE AIR FEED

New valve design, using famous I-R double kicker port principle, has larger direct air ports to both sides of piston — increases drilling efliciency 20% or more!

Retracts feed leg quickly by air pressure, saving time in moving from completed hole to new position.

For driiter dependability in a light-weight feed-leg drill, try the new JR-38C. Ask your I-R distributor or engineer for complete information.

Anti-Smog Devices Stimulate Vanadium Pentoxide Output

R . G . Sullivan, president of M i n erals Engineering C o . of G r a n d Junction, Colo. , said a five year contract signed by his f irm for the fu l l byproduct vanadium production of the M i n e r a l Products Division of Food Machinery and Chemical Corp . of N e w Y o r k Ci ty follows the recent vote of the CaHfornia legislature requiring anti-smog devices on cars and trucks.

In citing the Cal i fornia action, Sullivan said the catalyst "vanadium pentoxide" for Cahfornia's 7,000,000 vehicles alone would amount to approximately 80,000,000 p o u n d s , which is more than six times the nation's current output. Minerals E n g i neering wi l l produce vanadium pentoxide from the by-product vanadium.

" A rapidly increasing demand for vanadium is assured as vanadium pentoxide is the least expensive as a main constituent, as a catalyst, for vehicle smog control units," Sullivan said.

Vanadium pentoxide is now being used at the annual rate of 12,000,000 pounds in the United States, according to the U . S. Bureau of Mines .

Sullivan said that up to now major uses were for alloy steel, as a catalyst, and atomic energy uses as a pure metal.

N e w facilities w i l l be set up hy Minerals Engineering to handle the by-product vanadium that w i l l be shipped from the Pocatello, Idaho plant of F . M . C . ' s M i n e r a l Products Division, Sullivan said.

T h e Minerals Engineering Co . president said that his company wi l l construct a new refinery in Salt Lake City , adjacent to the company's exist

ing tungsten refinery, to produce^'fcorn-

mercial grades of vanadium pentoxide.

U n d e r the terms of the new .contract,

Sullivan said, initial shipments wi l l be

made by Food Machinery'and Chemi

cal Corp . in early July.^He estimated

that his company wi l l 'begin produc

tion at the new Salt "Lake Ci ty facil

ities within 60 days of receipt of the

first shipment.

Minerals Engineering C o . is a lead

ing producer of tungsten and a pio

neer in mining and treatment of vana-.

dium-uranium ores. T h e company's

operations are carried out in three

states—Montana, U t a h , and Colo

rado. T h e f irm also operates in M e x

Third Semi-Annual Report Released by OME

T h e Office of Minerals Exploration received 12 applications for minerals exploration assistance, entered into five new contracts with mine operators for exploration assistance, and certified discoveries on 12 projects during the last half of 1959, according to its third semi-annual report.

T h e report was prepared for transmittal to Congress pursuant to Public L a w 701, 85th Congress. T h e report says that public interest in the- exploration assistance program is somewhat less than that shown in previous periods.

T h e Office of Minerals Exploration succeeded the Defense Minerals E x ploration Administration as a permanent agency of the Department of the Interior and participates with private industry in exploration for critical and strategic minerals.

D u r i n g eight years of operation, the financial assistance granted by the Defense Minerals Exploration A d ministration resulted in the discovery of mineral reserves having a net recoverable value of $800,000,000.

7000 degrees . . . an inferno approaching that of the sun's surface

has been created by the scientists of Union Carbide. The energy comes from

the intensely hot carbon arc. Through the use of mirrors, the heat is reflected

to form a single burning image of the electric arc at a convenient point.

CaUed the arc-image fiu-nace, it extends the hmits of high-temperature

research on new materials for the space age.

For years, mammoth carbon and graphite electrodes have fired

blazing electric furnaces to capture many of today's metals from their ores

and to produce the finest steels. But, in addition to extreme heat, the carbon

arc produces a dazzling light that rivals the sun. In motion picture projectors,

its brilliant beam floods panoramic movie screens vi'ith every vivid detail

from a fihn no larger than a postage stamp.

The carbon arc is only one of many useful things made from

the basic element, carbon. The people of Union Carbide wiU carry on their

research to develop even better ways for carbon to serve everyone.

Atomic Product May Help To Provide Cleaner Air

T h e possibility of using uranium to combat urban air pollution was one of several topics discussed by government scientists during a meeting A p r i l 12-13 at Reno, Nev. Researchers from the Bureau of Mines joined representatives of the Atomic Energj' Commission and certain A E C contractors at the Bureau's Reno M e t a l lurgy Research Center to review progress in intensive studies through which the Bureau hopes to develop industrial applications for depleted uranium which is available in the form of uranium hexafluoride.

T h i s material is called "depicted uranium" because most of the fissionable component, U-235, has been removed in producing enriched atomic fuel. It has potential uses in several fields, the Bureau said.

T h e proposed use of this mildly radioactive material as a smog inhibitor envisions a depleted-uranium cat-alj'st that could be installed in an automobile-exhaust sj'stem to convert gases into harmless substances. Preliminary studies by the Bureau indicate the technical feasibility of such an application for uranium.

Other uses on which the Bureau has been conducting research would employ derivatives of depleted uranium in high-strength steels, in alloys for bearings, as a heavy medium for separating minerals from their ores, as a catalyst in processing oil from oil shale and in making high-octane gasoline, and to guard underground pipelines, ship hulls, and other structures from corrosion.

Pilot Plant Being Built To Process Semi-Taconite

Construction of a pilot plant on the Mesabi Range to process semi-taconite was announced by R . J . M o r t o n , Manager of Research for U . S. Steel's Ol iver Iron M i n i n g D i -

. vision. Ol iver wi l l locate the new facility near Coleraine at its present T r o u t Lake ore concentrator.

W o r k on the new plant is under way and at present consists of preparing concrete machinery foundations and modifying existing equipment. It is expected that the new plant wi l l be completed early next summer.

T h i s plant wi l l use a magnetizing roasting process and the basic piece of equipment in which the roasting is to be carried out w i l l be a rotary kiln. T h i s is a brick lined steei tube,

4^2 eet in diameter and 50 feet long. Successful magnetizing roasting requires the exclusion of air from the kiln and special equipment for sealing the ends of the kiln has been developed for this purpose. O r e fed into thc ki ln is heated to temperatures ranging from 950 to 1225 degrees Fahrenheit. By carefully controlling conditions within the kiln, chemical reactions change the nonmagnetic semi-taconites to a highly magnetic product. T h e capacity of this experimental kiln is up to five tons of ore per hour.

Af t er converting the nonmagnetic semi-taconite into magnetic material by processing it through the kiln, Ol iver explained, it is necessary to grind, concentrate and then agglomerate the kiln product before it can be used in a blast furnace. T h e latter operations are similar to those presently employed in magnetic taconite plants on the Eastern Mesabi .

Semi-taconite exists in substantial quantities on the Western Mesabi and other Minnesota Ranges. Ol iver believes its pilot plant operation at T r o u t Lake wi l l provide engineering data necessary to evaluate the commercial possibilities of semi-taconites.

Submarine Manganese Deposits Will Be Photographed

Rich submarine manganese deposits off west coast of Central America are to be photographed in an effort to determine their northern boundary. T h e U . S . N a v y Electronics Laboratory, San Diego, Cal i f . , w i l l have on board the survey ship, "Explorer," a deep-sea camera for photographing ocean bottom in an area where Russian oceanographic ship, "Vityaz ," reported 80 to 100 per cent of the bottom covered with nodules of manganese. Nodules were also high in nickel and cobalt content.

T h e second of two stainless steel "doughnuts" in which University of Cal i fornia scientists w i l l conduct atomic fusion research is being fabricated by Consolidated Western Steel Division in L o s Angeles. T h e first one was delivered earlier in 1959.

Each hollow steel doughnut, known to scientists as a torus, is designed as a primary containment vessel for a nuclear fusion research instrument at L o s Alamos Scientific Laboratory in N e w Mexico that has been named a "Perhapsatron," because of odds to be encountered in the research.

prepared text, yet several points were so pertinent that they should be repeated here, at least in outline form.

" T h e mining industry," he said, "is the last to pay attention to population increase." B y 1975, Battelle estimates that there wi l l be 245 million people in the U . S., although the Bureau of the Census estimates only 226 million. In the former figure, there wi l l be 65 million individuals of age 15 years or younger. Eighty million people, or one third of the total population, w i l l be below voting age.

Transportation has heen faced least squarely by the Eastern Railroads who do not care for passengers. Y e t the railroads dare not abdicate their responsibility to move people. A t present, they are interested in bulk shipments, hut the coal pipe line of H a n n a C o . is moving coal cheaper and faster than it has ever moved before. T h e days of rail shipment of bulk commodities may be passing. T h e canals are coming back, and the Ohio River is becoming a much more important highwa)' than the railroads that fringe its banks. Power is being shipped by power line at new ultrahigh voltages of 300,000 to 450,000 volts.

T h e one priceless possession which the railroads control is their right of

way. Unobstructed, it leads into the heart of every major city and offers access that cannot be gained bj' any other means.

T h e Ohio T u r n p i k e is just five years old. Y e t traffic has so far exceeded estimates that there is a water shortage at each of the service plazas, although the supply was considered adequate for 15 years when it was completed. Super highway construction wi l l not keep up with requirements and auto traffic faces eventual strangulation.

Continuing, M r . Anderson touched on other problems, such as energy. H e said that A d m i r a l Rickover was convinced that the nation would have to' depend on nuclear power hut not from plants as we now know them. A t the new reactor at Shippingport, Pa, , power costs are 65 mills which is certainlj'^ not economic. T h e cost must be brought down in 7 mills to compete. T h i s wi l l be possible in new thermo-electric bi-metallic units which wi l l operate with a stream of ionized gas, eliminating the boiler and its steam cj^cle.

T h e present surplus of food w i l l not last, and yet we are doing little to develop other sources. O f the 5,000 edible plants known, only 20 are being used for food here. T h e best farmland is being consumed by the ruthless urban expansion.

Recreation facilities wi l l require great expansion, for thej^ are in sad shape now. If improvements are not made, the tourists wi l l go to Europe, Mexico and elsewhere instead of visiting the National Parks and

mountains of the West , M r . Anderson believes that this demand wi l l be overwhelming and that the Wes t is not making an effort to meet this need if it expects to keep tourists coming out here.

Industrial competition wi l l increase as the European economy continues its remarkable advances. M r . Anderson said: "In my several trips to E u rope I never found the average E u r o pean. I found Italians in Italy, Frenchmen in France, and Germans in Germany, It is only here in the United States that you can f ind an average European. It is only here that you can have Chinese food in an Italian restaurant in an Irish neighborhood."

T h e European small cars were developed because the European could not afford a big car. H i g h gasoline taxes, narrow roads, and heavy taxation forced the development of the small car. Imported here, they were welcomed for the same reasons-—they were cheap and they required little gasoline. H e said, "It is possible to drive one of these small cars and park it in the city. Costs of getting there are not exorbitant, and the little fellow travels from traffic -light to traffic light with the same lightning speed as the big American car. In fact, if the trend to longer and lower cars had continued unabated, by 1975 the hig American auto would have been 107 feet long, with 7-inch wheels, and with the eyes of the driver level with the pavement."

T h e auto industry turned to the compacts, and now although Chrysler

is producing more cars than ever before, they are using less steel. A compact car takes 1000' pounds less steel than the usual small car. M o r e cars and less steel seems to be the picture.

F r o m this, M r . Anderson said, we should draw a parallel and learn a lesson. In the horse and bugg}^ days, there were only two makers of buggy whips. T h e y had no labor problem, no competition, plenty of raw materials and a fine product. "Yet they were dead when the buggy went out of business."

C u t your business plans to fit changing conditions and do not simply extrapolate figures to prove that if " X " pounds of " Y " product are used per capita, that a mere increase in numbers wi l l certainly increase the consumption of product * ' Y . " "Remember the buggy whip business," M r . Anderson concluded, "it went from capacity to oblivion with changing times, while population continued its spiraling climb."

T h e third speaker on the program was D r . L . M . Currie , vice president, Babcock and W i l c o x C o . , N e w Y o r k ,

Dr. L. M. Currie Babcock & Wilcox

H i s subject was "Nuclear Fuels and the Energy G a p . " T h i s address was too long and too pertinent to be briefed here. It w i l l be printed in fu l l in a later issue. In closing he said, " N o w the Russian military experts may have their doubts, but M r , Khrushchev says they wi l l bury us in economic warfare. H e may be right •—but I doubt it. I think, though, that regardless of what approach the 'big black bear' may make, we in the Free W o r l d must continue our upward progress. Advancement in development of nuclear power would be one way."

It was a profitable lunch for those who attended. T h e talks were timely, and the food was excellent.

Joint Luncheon Friday H e r m a n F e u c h t , vice-president,

American National Bank, as co-chairman for the A p r i l 22 luncheon program, introduced D r . Pau l F . Genachte, director. Atomic Energy Division, Chase Manhattan Bank, who spoke on the subject, " T h e Economic Future of Atomic Energy."

D r . Genachte has not been stampeded by the clamour that atomic power has failed to live up to expectations but has preserved his belief in

the potential of atomic power to help the U . S. and the world bridge any energy gap that may occur in the near or distant future. H e recognized the problems that remain to he solved, but is confident that there wi l l be a solution found. H i s article is given in fu l l in this issue of T H E M I N E S M A G A Z I N E .

Robert Henderson, manager Western Operations, Cl imax Molybdenum C o . , Golden, Colo. , as co-chairman of this joint luncheon, introduced Oscar L , Al tman, advisor. Research and Statistics Department, International Monetary F u n d , Washington. D r , A l t m a n presented his views on "'Fhe Role of G o l d in International Liquidity ." H e stated that the views presented were his own and did not necessarily reflect the official position of the International M o n e tary F u n d . A f t e r discussing the de-

velopment of gold standard in the latter part of the 19th century, he passed on to consider the structure of international reserves and the use of the world's supply of monetary gold. Nearly all monetary gold has now been gathered into official holdings. Economic developments since W o r l d W a r II have changed greatly the structure, ownership and distribution of these gold reserves. Whether they are adequate or not is a question that elicits many answers, from completely inadequate to more than adequate. "However, no amount of reserves wi l l be adequate," M r . Al tman said, "if the most important countries cannot learn to live within their means."

Frequent proposals to increase the price of gold, thus increasing substantially the amount of gold reserves, would devaluate the dollar, penalize countries and individuals who have kept their assets in dollars, and eventually give an upward push to prices. T h e effect on the Russian gold reserves would be substantial, "It is a matter of considerable surprise to me," he said, "to think that people who would instantly reject the idea of lending the U . S . S . R . $3 to $5 billion would seriously consider doubling thc price of gold, which would virtually present the Soviets with the same amount as a gift."

In closing, M r . A l t m a n said, " O u r international financial machinery has developed a great deal since the war, and it w i l l continue to develop. A realistic appraisal of present conditions, and of the foreseeable future, shows us prohlems but not crises; it suggests that we should be concerned but not fearful; and it counsels us to perfect the international financial structure we already have, rather than embark on far-reaching measures for which wc are not ready,"


T H E M I N E S M A G A Z I N E has requested permission from M r . A l t -man to publish his address in fu l l in a later issue of the Magazine. Sold and Silver Banquet

Speaking to more than 1,000 persons at the G o l d and Silver Banquet, Lyndon B . Johnson, Senate M a j o r i t y leader and unannounced Democratic presidential candidate, urged the organization of a joint executive-legislative-industry commission on minerals to provide a sane, progressive national minerals policy. Such a commission, he said, could press for action where action is so badly needed.

"Further," Senator Johnson said, "as your fine governor, Steve M c Nichols, has proposed, let us make an inventory of our mineral resources— a thorough job of mapping and exploration so the nation may know what it has today, and what resources it can depend on in the future."

H e told the group that development of our mineral strength was vital to the nation's security, and he warned that "if we neglect them now, America cannot remain in first place in the world ."

It is important, Johnson said, that American industry thrive, not just survive. " T h e whole country," he declared, "must be brought to understand that your problems are not yours alone—but that they are in a very real sense the problems of all the people."

Another speaker, Sen. Gordon A l -lott ( R ) of Colorado, told delegates he had suggested the treasury department raise its price for silver to $1 an ounce. T h e suggestion, he said, was one of several included in a letter

he wrote recently to Treasury Secretary Robert B . Anderson.

Other policy changes suggested by Al lott included:

T h a t the treasury cease drawing upon free stocks for its coinage requirements. Other treasury holdings can provide this, he said.

' I'hat in the future the treasurv use free stocks for the purpose of establishing conditions that wi l l insure no market dislocation when free stocks are exhausted.

" A reasonable projection of U . S. industrial and coinage requirements for silver indicates that under present

treasury rules free stocks wi l l be exhausted in three to five years," A l lott said.

W h e n that happens, he warned, silver wi l l suffer a shortage-induced jump in prices, consequent overproduction and then price breaks.

" W o u l d it not be better," he asked, "to amend treasury sales policy in anticipation of the future course of the market; to revise sales policy so as to promote stability in the silver market, rather than to promote instability?"

Commemorative plaques were presented at the banquet to two men and three mining companies for achievements within the industry. T h e awards were made by George O . A r g a l l , J r . , editor of M I N I N G W O R L D , to Johnson Crawford , (" M a n of American M i n i n g for 1959") assistant manager of mines for N e w Jersey Z i n c Co. , whose eastern Tennessee property is the largest zinc mine in the nation; to Pima M i n i n g Co , of Tucson, A r i z .

the mining industry should not expect too much in the form of new-markets if the nation mobilizes for an emergencj'.

" T h e national stockpile of 75 strategic materials can now meet emergency mobilization requirements,'' Price said. "I don't foresee any immediate findings which would justi fy major changes in the stockpile."

Stockpile objectives, Price stressed, are governed only by national security.

" M y office has an obligation," he said, "to resist all efforts to use the stockpile as a means of influencing prices or otherwise interfering with normal operations of the nation's economy, but this does not mean indifference to the problems of any industry or to the general health and vigor of the country."

Price pointed out that O C B M maintains a constant lookout for trends toward the defense use of newer metals and cited current research in developments in beryllium, molybdenum, tellurium and tantalum.

In a speech also given at the world famous Sowbelly Dinner, former Sen. George W . M a l o n e of Nevada called for Congress to "retain its constitutional responsibility to regulate foreign trade and the national economy." T h a t responsibility, he said, has been abrogated by the executive branch in the last 20 years, generally to the detriment of American interests.

M a l o n e saw the nation's capital as the root of most of the mining industry's woes. H e said: " O n l y W a s h ington, D . C , could make ghost towns out of the prosperous mining camps of America. O n l y Washington, D . C , could shake the foundations of the business structure of America through imports of cheap labor goods, shutting down many industries and endangering the A m e r i can jobs and investments in productive enterprises, from mining to machine tools, and from cattle to tex-tiles . . .

Malone called for renewal of the Monroe Doctrine by re-declaring America's intention to repulse foreign intervention in matters of the Americas and for implementation of a lesser-known clause of the Monroe Doctrine—that the United States also maintain a hands-off attitude over the affairs of the rest of the world.

Palmer Sees Brighter Future Robert S. Palmer, executive vice

president of the Colorado M i n i n g Assn., said the mining industry picture had been brightened by the conference and that he looked "for an upsurge in the mining industry." B u t he warned that domestic miners wi l l have to fight hard with governments and conservationists if they intend to remain active and prosperous. H e said:

"It is up to the mining associations of the Wes t to fight and fight hard for proper recognition for the domestic mining industry . . . T h e federal government must do everything possible to keep the mines active and this includes the small mines as well as the large mines . . . Policies should be adopted which encourage production rather than discourage it." ( H i s address is given in fu l l in this issue of T H E M I N E S M A G A Z I N E . )

Resolutions Summarized Resolutions adopted at the con

vention called for:

(1) Encouragement of the mining industry through legislation so that the United States wi l l not continue to lose its skilled miners, mining scientists, engineers and geologists.

(2) Discontinuance hy the secretary of treasury of sale of silver from the treasury to consumers at a price below the world price, allowing the world price to seek its own level.

(3) Recognition by the Uni ted States that gold should seek its own price level. If international commitments would embarrass U . S. international agreements, then domestic-

allj'-mined gold should be provided with an incentive payment, similar to that paid in Canada and Australia.

(4) Extending uranium purchasing contracts beyond 1962 in the Uravan uranium belt, which includes southwestern Colorado.

(5) Consolidating federal and state inspection departments dealing with radiation to avoid duplication or conflict in establishing radiation standards.

(6) Maintaining lead and zinc quotas set by the president until an adjustable duty of 4 cents a pound on each metal can be imposed.

(7) Extending the manganese car-lot purchasing program another year to permit investors to realize a return on their investments.

(8) Enactment of legislation for small mines to permit tungsten production of up to 1,000 units a year per mine and establishing a unit price of $63.

(9) Retaining the system of mining location and opposing passage of any legislation, such as the W i l d e r ness B i l l , that would deprive the miner of his right to locate claims on the public domain.

South Africa Offers Diamonds For Mohole Driliing Project

A n offer from the Afr ican diamond industry has moved the "Mohole Project" another step toward realization. T h e "Mohole Project" is an attempt by a group of American scientists to dri l l through the Mohoro vicic discontinuity which bounds the interior of the earth.

I n d u s t r i a l Distributors (1946) L t d . , a South A f r i c a n company which markets the industrial diamond output from the A f r i c a n mines, has offered to provide the diamond dri l l stones required for the exploratory phase of the drilling, W i l l a r d Bascom, technical director of the A M S O C committee of the National Academy of Sciences, announced recently.

In a speech before the N e w Y o r k chapter of the American Society of Mechanical Engineers, M r . Bascom said the "Mohole Project" has received generous offers of support from many areas of American business. T h e South Afr ican company is the first foreign business to offer assistance.

T h e exact amount of diamonds required for the exploratory phase of the dril l ing project has not been determined, M r . Bascom said. Accord

ing to E . T . S. Brown, managing director of the South Afr ican company which offered the dri l l material, estimates have run as high as 50,000 carats.

Christensen Diamond Products Co . of Salt Lake Ci ty has offered to cooperate by producing dri l l bits with the diamonds supplied from South Afr i ca . A new type of diamond dri l l stone, designated as " D r i l l N o . 6," wi l l be tested in some of the dri l l bits.

T h e purpose of the "Mohole Proj ect" is to obtain continuous samples or cores of the rock layers beneath the deep ocean for scientific purposes. T h e plan is to dri l l a series of holes from a ship. 1'hese wi l l culminate in a hole which penetrates the M o h o and samples the material of the mantle, as the interior of the earth is called.

T h e exploration operation wi l l test techniques for holding a ship in position and for dril l ing in deep water. T h e first holes wi l l be shallow ones but they wi l l be beneath 12,000 feet of ocean. T h e engineering studies are well advanced and the A M S O C committee hopes to complete thc tests within the next year.

'Fhe information obtained can then be used to design a deep-drilling ship, capable of reaching to the M o h o , which is at least 30,000 feet below the sea surface. Under land it is at

least three times that deep. Since the deepest hole yet drilled on land is 25,340 feet, it is clear that with the present state of technology the hole must be drilled beneath the ocean.

T h e end product of this grand-scale experiment wi l l be advanced engineering knowledge about how to do deep dril l ing at sea, and scientific knowledge about the history and structure of the earth.

(Editor s Note: More details about "Operation Mohole" by WHlard Bascom. x-il, were published on pages 15-19, February 1960 issue of The Mines Magazine.)

Columbium Will Be Theme Of AIME Symposium

Columbium, the lustrous, steel-gray element of many important uses, including nuclear reactors, jet engines, and other high temperature applications, w i l l be the theme of a symposium sponsored by the Hudson-M o h a w k Section of the American Institute of M i n i n g , Metal lurgical , and Petroleum Engineers, at the Hote l Sagamore, B o l t o n L a n d i n g , Lake George, N .

Forward with the

Mining Industry By ROBERT S. PALMER

Executive Vice President, Colorado Mining Association

ROBERT S. PALMER

Colorado is a mecca of raw materials of ever-iacreasiiig variety. Tlic expanding use of raw mate-trials and thc economic progress of mankind go band 'in hand. In our striving to improve the lot of mankind, we have drawn more and more on mineral resources, for the advancement of our envied standard of l iving.

A t times, supplies of raw materials—-particnlarly the minerals—have been inadequate to meet current needs. "With increasing world population, it is recognized that mineral deposits are irreplaceable and considerable concern has been evidenced that they may not be sufficient to meet the needs of the future. These anxieties are supplemented by the dependence of mil i tary security on adequate minertd resources, essential i n emergencies which arise f rom time to time where they are indispensable in modern warfare.

Premium Price Plan Recalled Many remember the days of the Premium Price

Plan, wiieu the Federal Government was doing everything possible to encourage the production of lead and zinc i n the United States. Bonuses were paid on low grade production. Some remember the excessive prices that the United States Government was forced to pa,y for foreign production during periods of shortages i n the United States.

The exhaustible nature of mineral deposits creates problems of depiction, which are not present i n products f rom animal and vegetable sources. Substitutions have been resorted to by some industries i n times of shortages, but in the main the basic materials are as essential to man's welfare today and wi l l be tomorrow.

Passing Through Period of Plenty AVc are passing through a period of plenty. Heavy

un];>orts have ruined the markets for many of the producers i n America but this need not be a normal condition, for time wi l l prove that as standards of l iv ing increase in far-away lands, more and more products of mines wi l l be nsed by those people, and our own country wi l l have more need of the products of domestic mines.

The heavy stoclqjile of minerals was largely supplied f rom producers abroad. Minerals account for

24

over 80 per cent of the investment the United States has made i n its stocltpiles of strategic materials. Onr reserves of minerals i n Colorado are plentiful . Perhaps there arc more Iniown reserves of the essential minerals in the state today than there have been at any other time in our history''. The West has grown i n economic importance i n the production of minerals, but economic factors have forced many close-downs. Thc facts are that quantity economically recoverable at any given time depends on price, cost of production and perhaps the current status of technology.

Ever-Changing Use-Patterns

Surveys of the mineral industry disclose that there are ever-changing use-patterns i n raw materials. In the 70's, for example, approximately 35 minerals were adequate to support the economy of the United States. A recent survey indicates that the list now exceeds a hundred and that the new minerals are indispensible in. modern industry. It is anticipated that the list wi l l ever increase as we expand into the atomic age, \\'ith its accompanying intercontinental ballistics, missiles and space ships.

Beryll ium, zirconium, uranium, titanium, boron, hafnium, rhenium and the rare earths metals, \\'hich arc becoming more important in today's advance use of metals, were perhaps unknown as useful metals a hundred years ago. Some of the metals arc not sharing prominence i n this advance forward, bnt this does not mean that tomorrow's technology wi l l not advance them ito places of leadership.

The demand for iron has increased tenfold; for zinc, twenty-two; copper, thirty-four. Such metals as aluminum have increased i n consumption over six thousand times. A t our annual Convention speakers have pointed out from, time to time that America, with 7 per cent of the world's population, consumes better than 40 per cent of the world's mineral supply. The per capita consumption of minerals varies greatly among the nations. The world citizen outside the United States consumed only 1.5 kilograms of copper i n 1955, while M r . American consumed an average of 8.5 kilograms. M r . European consumed 4.7, while the Russian consumed only 2.2.

THE MINES MAGAZINE • MAY, I960

Use of Metal Reflects Living Standard

The remarkable thing about those figures is that they disclose the different standards of l iving enjoyed by the different peoples i n different countries. The greater users of metals—the higher the standard of l iving. The average Russian uses only one-fourth as much energy or metal as his American counterpart. It might be explained, of course, that Russian consumers arc being neglected to a certain extent to permit heavy concentration on mili tary production, but whatever the facts are—-it is clear that metals are highly essential to a highly productive community.

No satis i'action can be realized hy us when we know of the low standards of l iving i n many parts of the world. Bu t the point is, that as these countries advance, people therein wdl demand the use of more metal. More metal w i l l he used as the standards of l iving advance. I t is equally true that as mili tary requirements grow i n foreign countries, the governments themselves wi l l place heavier demands upon mineral production.

Exploitable Resources Inadequate

I f world averages should move up to those presentl y enjoyed by the United States, or even those of Free Europe, exploitable resources as we know them would shrink alarmingly. This assertion does not take into consideration the additional factor of increased world population. The inescapable conclusion, however, is that as we march forward, world exploitable resources m i l become grossly inadequate.

Some interesting studies on this subject have been compiled by the U . S. Bureau of Mines and various agencies from time to time. A n illustration is given with respect to copper. The exploitable reserves arc estimated at a hmidrcd million metric tons. This is only equivalent to 29 years' supply at the 1956 rate of consumption. Similar impressive figures could be given for the other metals. These figures are undoubtedly unimpressive to today's producer, struggling to survive i n a period of depressed prices and overproduction. However, it shoidd encourage those who seek to hold onto their mining claims for the long pul l .

Mineral Scarcity inevitable

The United States cannot long survive without an active, healthy, going mining industry. The outlook for the long time futin-e is undoubtedly mineral scarcity, particularly with the common non-ferrous metals.

The present reserves of lead are equivalent, according to these studies, to only 19 years' supply at the 1956 rate of production and those of zinc at 23 years.

In a country which has a vital need for metals, the cost factor w i l l eveutu.ally become secondary. No one wi l l contend that today's prices of lead and zinc are realistic, when one takes into account the cost factors involved i n the production of tliese metals. The same could be said of fluoi-spar and many other- nonmetals, as well as the precious metals.

The uranium industi'y proved that once a market is created with price incentives, remarkable results are obtained in discovery and development hy the prospectors, the engineci's and the geologists.

As Blmev Pehrson pointed out in his remarkably fine paper a few years ago, columbium was designed out of many high-temperature alloys because of scarcity. It now appears that the commercial reserve, including those recently found i n Colorado, is far

greater than previously envisioned and columbium wi l l soon play a greater part i n the high-temperature field.

New Discoveries Predicted Therefore, anyone who attempts to appraise the

world's reserves of different metals is walldng upon thin ground. Many new discoveries w i l l be found and I predict that many new discoveries w i l l be made of tremendous importance within the state of Colorado, provided of course that the tax laws are kept in bounds and that conservationists do not get the upper hand in making the public domain unavailable for the use of the mining industry.

Technical men in the mining industry have done a great job in bringing into the realm of commercial utilization lower and lower grade ores and undoubtedly there w i l l be additional advances i n this field of activity.

.Lower and lower grade materials w i l l he used with the advancement of civilization. It would, however, be unrealistic to assume that this progress can be accomplished without increases i n price and as prices rise, the competitive situation with respect to other raw materials naturally wi l l increase.

Wider Commercial Use of Minerals The long pul l outlook for wider commercial use of

al l of the minerals is favorable. It is equally true that experience has taught us during the last century that discovery of rich deposits has not kept pace with expanding needs.

I t is said that a greater part of the world's metal supply is now derived f rom resources whichj at the turn of thc century, were uneconomic. Revolutionary new methods of scientific ore finding have been defused. Research i n this field is going forward rapidly.

Energy Resources Inexhaustible .Energy resources may be regarded as inexhausti

ble. Coal reserves exceed a thousand years' supply at current rates of use. O i l and gas are less abundant. Estimates here have been that the total recoverable natural oil and gas in the earth are approximately equivalent to a two hundred year supply at current rates of use, but of course consumption is advancing rapidly.

The Rocky Mountain Oi l and Gas Association has pointed out that reserves of crude oil i n the United States are equal to only a 13 yea,r supply at current production rates and those of natural gas at 22 years. Our oil shales wdl undoubtedly come into play and •\ve wi l l hear much about the potential of oil shale at this Convention.

Atomic energy is very much on the horizon and i f it develops that this is not sufficient to meet man's needs, then of course there arc other ideas advanced, including the utilization of solar and outer space energy sources.

World Nationalism Growing No one can deny that throughout the world na

tionalism is growing. "With the growth of nationalism, many political factors are introduced that infiueuce the availability of raw materials for the utilization of mankind. This is particularly true of industrial nations which depend on baclnvard areas for supplies of some materials.

It has been an economic safety factor for the

United States to have a backlog of domestic produc

Resol uti ons

Committee Report

Coloracio IVIining Association

The efforts of the Western Senators, Congressmen, and Governors, in their support uf the mining and milling activities of their constituents are warmly commended. Our thanks also go to our many supporters in Congress of the South and East who, against entrenched opposition, have recognized and urged the vitaS need for a bold, sound and constructive mineral program. Additionally, we are grateful for the united cooperation of other mining organizations aliied with us in fighting for the betterment, and indeed the very life, of the mining industry.^ In presenting this declaration to the nation, we are confident of the continued support of all of these friends and allies, and others everywhere, who understand that this great country can only prosper from a healthy and active mining industry.

This industry is proud of its continued scientific achievements in metals and minerals. It recognizes its obligation to carry these achievements still farther, to increase the output of metals and minerals, and to conduct more and more research into means whereby metals and minerals will aid the technological advance of the United States. Through these efforts our national defense can be strengthened and our high standard of living continued.

We declare that mining will prosper only in a good environment and under a favorable economic policy. The industry has always borne it share, or more, of the tax burden. Any greater load imposed on the industry, at any level of government, would he a costly and shortsighted expedient.

Taxation depletes mine reserves faster than exploitation, and results in bad conservation. When the miner raises his cut oif in value of ones mined, he can never go back and resort to the marginal grade which is in effect abandoned. . That mineral policy is best which en

courages all developers and users of our national resources. The prospector, miner, mill operator, and manufacturer, all should receive equal treatment and be allowed to share the same economic advantage.

We advocate a greater recognition of the risks involved in mining. No industry incurs more. Any tax system which discourages risk capital from entering mining cannot help but cripple the industry and thereby harm the nation. The zeal of

26

private endeavor in developing a strong domestic mining industry should not be dulled by governmental policy, particularly as the same may be affected by importation policies.

We urge a greater awareness on the part of the nation that miners must be encouraged to replace exhausted deposits. Otherwise, there will be inadequate domestic reserves upon which we can unqualifiedly depend to meet the mounting and urgent necessities of future defense and industrial needs. This encouragement must come in the shape of fair taxation, an understanding government policy, and a united effort on the part of all those associated with mining and its products.

It is in the light of these general declarations that we submit our resolutions.

Administrative Proceedings Reform

Elementary justice requires a single agency to administer the laws of the Public Domain.

Interference by and between various bureaus or departments of government in the administration of the public lands should be eliminated,

Distinct from administration of the laws is the present system conferring quasi-judicial authority on the very department that is contesting a citizen's right to locate, settle, lease or enter. To have one party to a controversy act as judge and jury is unfair to the point of absurdity. Such a system is obnoxious to simple fair play and the separation of powers.

Procedures should be promptly reformed, as is now being urged by the American Bar Association, whereby the Administrative Procedure Act will provide independent hearing examiners,

Mining Locations are Private Property

The Department of Agriculture, the Forest Service and Bureau of Land Management should exercise moderation in making things tough for the small miner. Under recent practice, it is being attempted to cancel out mining locations by publication in local newspapers. We remind all miners and all federal officials that the vested rights of a miner in a location, duly kept alive by annual labor, cannot be taken away by notices in any publication. Rights under a valid loca

tion are property. They can only be divested by doe process of law. Due process means actual service of notice on the individual owner and not a mere constructive notice which in all probability he will never see.

Single Purpose Withdrawals Recognizing that a withdrawal of the

public domain for one purpose is inconsistent with multiple use, we continue to advocate free enterprise uses of public land. This has been the Americans' right and privilege since 1781. It has prevented "landlordism" by a central government on the Socialist model of other nations.

We oppose the single-purpose withdrawal of public domain advocated in the proposed National Wilderness Act, and we commend both Senators O'Mahoney and Allott for their constructive efforts in our behalf.

Public Lands and the 1872 Act The time-tested system, established by

the General Mining Law, for locating and patenting mining claims, has proved best. It encourages enterprise and regulates naturally the development of the Public Domain.

We denounce any delegation of power or responsibility for law-making to any government board, bureau or department. Their plans or recommendations should never become law, without express enactment by Congress.

Silver and Gold New uses are developing rapidly for

silver in the new arts, in nuclear energy and electronics, and large quantities go into use as a catalyst.

Last year the government used 40 million ounces for coinage. The national Treasury has the largest stockpile of silver in the world, and over 1 billion ounces are in circulation as coins. Outside of this, tbe Treasury has stocks of 2.1 billion ounces, of a value something under 2 biUion dollars. World silver production was 205 miiiion ounces, while world consumption was 259 million; and the authorities estimate that_ world consumption will exceed 300 million ounces in 1960, aside from large hoarding in many parts of the world.

THE MiNES MAGAZiNE • MAY, 1960

As for goid, 11.7 billions of dollars in reserve are necessary to back outstanding American currency, plus deposits in the twelve banks of the Federal Reserve System. This leave 7.9 billions of dollars seemingly free, but the Secretary of the Treasury recently testified that foreigners have short-term balances here, convertible into gold, totaling 17.6 billions. From this it is apparent that, after domestic and foreign operations are balanced off, we really own no gold at all.

Therefore we advocate that the Treasury stop the sale of the people's silver and devote it to monetary uses only, to supply the increasing demand for that purpose. We ask that silver be allowed to seek its own level in the market.

If gold is not to be allowed to seek its own price-level, then a government incentive for domestically mined goid should be provided, to permit domestic gold-mining at a profit, as,is being done by Canada and elsewhere in the British Commonwealth.

Uranium The Atomic Energy Commission is com

mended for its recognition of the need for a stable domestic uranium procurement program and for not extending its foreign commitments, but rather for "stretching out" such contract commitments over a longer period of time.

The A E C should be advised of the necessity of continued diligence in contract negotiations over the various areas of domestic uranium program in the United States. Specific attention should be directed to the fact that the Uravan Mineral Belt does not yet have contracts for the production of uranium concentrates extending beyond 1962, Al l mine operators need information with respect to contract extensions in order to plan mine development. It is anticipated that if A E C does not make such information available in the reasonable future on the Commission's anticipated rate of production on the Uravan Mineral Belt, certain mines will have to be closed which could result in their abandonment. This could involve a loss of the remaining ore reserves of such mines, and a loss to the entire nation as well as to the mine operators.

The various inspection departments of the federal and state governments dealing with radiation should be consolidated and work in a unified way to avoid duplication of efforts and inconsistent standards in radiation problems.

The domestic uranium industry has the ability to police itself in radiation problems. The lack of definite standards and the lack of dissemination of consistent information makes such self-policing impossible; therefore, the A E C , the United States Department of Labor, the United States Bureau of Public Health and various other state and federal agencies involved in the establishment of safety standards with respect to radiation should speedily work towards definite and certain standards.

Lead and Zinc The Mining Conference expresses its

appreciation for the courage shown by the present administration in invoking quotas on lead and zinc. It Is recognized that while the benefits are meager in many instances, nevertheless the program is important to the industry and should be maintained until legislation may be enacted to provide more permanent protection.

We urge a four-cent duty on lead and zinc, as advocated by the National Emergency Lead and Zinc Committee. We further advocate enactment of legislation designed particularly to aid and assist the small miner, whose production of lead and zinc combined, does not exceed five thousand tons of metal a year.

Manganese We favor a continuation of the Man

ganese Car-lot Purchasing Program for another year so that domestic producers, recently and unexpectedly cut off, maj' realize on their investment, and we further favor any program to encourage installation of treatment plants for the recovery of domestic manganese where economically feasible.

Tungsten That the tungsten producing industrj'

throughout the nation be maintained bj' an incentive payment of the difference between the available market price, and the 19S1-S6 price of $63.00 per unit; such payment to apply oniy to the first 1000 units annually offered or sold by each producer.

The effect of such payment will be to maintain several hundred tungsten mines in condition to produce ore when needed; will serve to retain the experience of mine operators and workers at the point of need; and will keep alive the knowledge of the location and sources of tungsten ore.

The cost of such a plan will be remarkably low. It has been calculated that the nation-wide cost of this program would be less than $5,000,000, annually, or a cost comparable to a single military aeroplane.

Loss of Miners and Scientists The closing of the mines has reduced

our national force of skilled miners and has seriously threatened our supplj' of scientists, engineers and geologists. Incentive is diminished. These specialists cannot be replaced at will. Only a healthy raining Industry can maintain capable personnel in adequate numbers. America may find itself with a critical shortage of mining know-how in the years to come.

Oppressive Venue Requirements We urge passage of H.R. 10089 now

pending in the House of Representatives of the 86th Congress, 2nd Session, which provides that a civil suit to review any action by a federal agency in which the defendant is an officer of the United States, or a person acting under him, or an agency of the United States, may in future be brought in the judicial district where the plaintiff in the action resides.

That is not now the case. With very few exceptions, the official

residence of those superior officers and agencies is the District of Columbia; and under present law our miners and others must bring their suits in far-off Washington, This creates a great and usually prohibitive expense for persons residing in the West; It compels them to betake themselves and their witnesses to Washington, to try their cases there, and it causes many just suits and claims to be abandoned. It deprives our miners of judicial remedy.

Tbe present state of the law is reminiscent of the days before our National Independence, when American colonists often had to undertake a voyage to Lon

don to present their causes before the Royal Ministers or other British officials.

We earnestly petition Congress to remedy this present evil.

Duplication as to Mine Safety Duplication of agencies dealing with

mine safety is burdensome and needless. State officials of Colorado are doing excellent work. A duplicating federal agency is not needed. Federal government agencies should stop seeking new waj's to spend taxpayers' money and should search instead for new methods to reduce expenditures.

Free Trade 'Tree trade" is the most costly and

ruinous measure that can be inflicted on the American workmen and people. Standards of living in foreign countries will not be raised by forcing American labor and industry to lower their wages and prices to match the labor-costs of exploited workers of other continents. Fair competition cannot exist, nor can a good standard of living be maintained, without tariff protection. No import should ever be admitted duty-free or at a tariff rate that will cause American mines to close or depress the wages of American workmen.

Our mines throughout the land are in distress, persons engaged in mineral production are being forced out of employment, communities where mines have operated are fading into ghost towns. Al l new wealth comes from the ground, but little is now coming from the mining regions of America,

Revive the Constitution We petition Congress to take back its

constitutional duty to regulate foreign commerce, adjust duties, excises and imports. The agency for this is the U. S. Tariff Commission. The ignominious Trade Agreement Act of 1934 and ali measures like it should be relegated. We urge a re-examination of the International Monetary Fund and the Bretton-Woods Monetary Agreement. We do not believe that thej' benefit this country.

Taxation of Non-Producing Mines The present gross inequity and absurd

ity in ' appraising non-producing mines in most Coiorado counties have reached the height of injustice. In some of them it is as high as $50.00 per acre for all claims regardless of value, when the market value is practically nothing.

Recent examples are: San Juan County $50.00 per acre; Summit County ,$40,00 per acre; Ouray County $36,00 per acre;

In Lake County, some non-producing claims are assessed per acre at $68.00, $50.00, $49.00 and $30.00, respectively.

These are only a few examples. The Colorado Tax Commission should

bring about a uniform, fair and reasonable evaluation per acre of non-producing claims throughout the state.

Our Executive Vice President We continue to be grateful for the

capable work of the Association's Vice President Mr, Robert S. Palmer, and for his tireless efforts for the Mining Industry in Colorado and America. Mr. Palmer has devotedly furthered the interests of the Mining Industry for many years, and we express our sincere thanks to him.

The Economic

Future off

Atomic Energy

By Dr. PAUL F. GENACHTE

DR. PAUL F. GENACHTE

Last yeai" i n reviewing with you the f ield of atomic energy as a new source of energy, we discussed its relationship to the mining industry i n which quite a few of you are basically interested. Although the essential conclusions we reached a year ago are still va l id today, a few new and important factors pei'mit us to make an estimate of the situation with a greater degree of knowledge.

I would, f i rs t of all, like to mention that i n the f ie ld of controlled fusion or thermonuclear energy, good progress continues to be made in the study and understanding of the behavior of hot plasma. The current stress is on learning about the behavior of superheated electrically charged gas—thc "fourth state of matter"^—-which constitutes the i^lasma referred to i n thermonuclear research. Thc achievement of a controlled thermonuclear reaction wi l l , f rom all present indications, require many more years of intensive basic study aud hard work before success becomes a reality. The "taming of the hydrogen bomb" was subjected to a searching re-evaluation following the Geneva Conference on the Peaceful Uses of Atomic Energj ' i n 1958. A more basic approach to the problem has heen decided upon.

l-iast year, i t was decided to delay thc construction of very lai'gc mechanical devices for conducting research on thermonuclear reactions, and the opei'at-ing costs of the AEC-f inaneed program for the fiscal year 1960 are being held at about the same level as for the fiscal year 1959, i.e., approximately $36 million.

Cooperation With Other Nations

"With the Bri t ish, we now have a joint research program in the f ie ld of controlled thermonuclear reactions permitting an exchange of iuformation free f rom the barriers of classification. Some cooperation exists in this f ie ld even with Russia. We certainly need not fear competition f rom this source of energy now or in the near future when we discuss the outlook for atomic energy i n fission reactors.

Neither should we be concerned by the development of thermoelectric and thermo-ionic devices i n which heat energy is converted directly into electricity. These devices w i l l f i n d applications i n space ve-

THE AUTHOR Dr. Paul F. Genachte, vice president and chief

marketing officer of the International Department and director of the Atomic Energy Division of The Chase Manhattan Bank, joined the hank in 1934 after 20 years m public utilities ivorh in Belgium and Mexico. His broad engineeiing background also includes experience as power consxdtant in Ceylon for the World Bank.

A U.S. citizen, Dr. Genachte tvas boi^n in Brussels, Belgixim, July 9, 1909. He graduated from Brussels University (B.S. in '32), obtained Ms M.S. in electii-cal engineenng from Massachusetts Institute of Technology in '33, and his Ph.D. from California Institute of Technology in '35.

In 1956, Dr. Genachte represented the Interna-tional Chamber of Commerce at the organizational meêtings of the International Atomic Energy Agency held at the United Nations headquarters in New York and aho at the general conferences held in Vienna in 1957 and 1958. Also, as a delegate of the ICC, he attended the UN Conferences on the Peaceful Uses of Atomic Energy in Geneva in September 1955 and again in 1958.

Dr. Genachte is a member of the American Nuclear Society, Atomic Industrial Eorum, Association of Applied Solar Energy, American Institute of Electrical Engineers, mid American Institute of Chemical Engineers. He is a direotor of Firth Sterling, Inc., Nuclear Science & Engineering Corp., and Homestake Mining Co.; chairman of Nuclear Industry Committee of the Investment Banker.'^ As.m.; vice chairman of the Nuclear Energy Committee of the National Association of Manufacturers; vice chairman of the International Affairs Committee of the Atomic Industrial Forum.

hides and i n small portable plants in remote areas. Their output w i l l be measured only in kilowatts, but certainly not in the thousands and millions of Idlo-watts which our country and the rest of the world need for continued economic growth.

A E C Budget for I960 The present Atomic Energy Commission budget

for the fiscal year 1960 calls for expenditures of ap-


proximately $2.7 billion. This is about the same amount that was expended in thc fiscal year 1959. This amount includes—and this is important to you —close to $740 million for raw materials, i.e., mainly purchases of uranium oxide (UsOs) f rom U . S. mills and those i n Canada and other nations.

The known uranium ore reserves i n the United States as of Dec. 31, 1959 amounted to appz'oximately 86 mill ion tons containing .28% UsOg, or a total of 240,000 tons of uranium oxide. The proven reserves in Canada amount to 377 miiiion tons of ore with 380,000 tons of uranium oxide. The South A f r i c a n uranium-bearing gold reefs hold 1.1 bil l ion tons of ore containing 370,000 tons of uranium oxide.

Uranium Oxide Production

Uranium oxide production i n the U . S. last year amounted to slightly more than 15,000 tons. Pur-ciiascs abroad totalled 18,100 tons, with 13,700 tons coming from Canada and the remainder f rom South Af r i ca , Australia, the Belgian Congo and Portugal. The U . S. is the largest single producer of UaOg.

Our mil l ing capacity in the U . S. could be increased by a few more mills i n southeast Texas, Nevada and North and South Dakota, but this would not result in any substantial increase over the present mill ing capacity of 22,000 tons of ore per d a y -equivalent to some 20,000 tons of uranium oxide por year. I n fact, it is likely that the output f rom onr domestic mills unt i l the end of 1966 w i l l uot exceed 18 to 19,000 tons of uranium oxide per year.

A E C Agreement with Canada

A s you know, the bulk of the Canadian output is delivered to the U.S. and the present level of mi l l ing in Canada, as I indicated, is about 14,000 tons per year. The A B C could have exercised options before March 31, 1961 to extend the present contracts through 1966 at the same price of $8 per lb. of uranium oxide, to be paid to onr domestic mills. On Nov. 6, 1959, the A E C announced that i t would not exercise its options, bnt i t did agree, to a stretch-out arrangement with Canada to purchase uranium concentrates i n the post '62 period through Dec. 31, 1966.

The new plan provides for a single contract between the Commission and Eldorado Min ing and Eef in ing instead of the several contracts which had existed heretofore, each covering an individual operator i n Canada. The total pounds to be delivered and the prices to be paid under existing contracts remain unchanged. In order to help the Canadian companies meet their financial obligations on their bonds, debentures and loans, advance payments of $2.50 w i l l be effected for each pound deferred at approximately^ the same time as deliverj^ would have been made had there been no deferment.

Similarly the United Kingdom, which receives about 10 per cent of the current Canadian uranium shipments, has offered to make an additional advance payment of $1.50 per lb. on any portion up to 16 million lbs. of the amount covei'ed by their contracts, which can be deferred into the period Jan. 1, 1965 through Nov. 30, 1966. This solution, which was not altogether welcomed in Canada, wi l l , nevertheless, I am sure, turn ont to be mutually advantageous. It certainly is a rational solution to the temporary gap between production and demand of uranium about which I w i l l comment later.

Canadian Companies Consolidating

A s had been anticipated, the stronger companies i n Canada are buying contracts f rom the less successf u l operators mid thus they are assuring themselves of continued operations. I am sure that you know that four important uranium oxide producers i n Canada—Algom, Mil l iken Lake, Northspan and Pronto —^will merge into a new company, to be known as Rio Algom Mines, L td . The conversion of existing shares of the amalgamated companies into shares of the new company may leave some stockholders unhappy, yet there is no doubt that it is the only logical solution i n view of the present circumstances.

Another Canadian producer is Consolidated Deni-son which is purchasing Can-Met Explorations, L t d . through an exchange of shares. Other mergers and acquisitions w i l l certainly take place this year in Canada. It seems to me only logical that most Canadian mills, on a reorganized basis, w i l l wish to stretch out their operations and, therefore, we should expect a gradual reduction i n the output f rom Canada over the period unti l 1966.

South African Contracts

A s you know, the South A f r i c a n mil l ing contracts were signed on a ten-year basis with some expiring i n 1964 and others i n '65. This circumstance should also point to reduced purchases of uranium oxide f rom that source in the future.

F r o m a total Free Wor ld production today of some 33,000 tons of uranium oxide, we should expect this figure to gradually come down to a figure of perhaps 25,000 tons in 1966. Our domestic mills in 1966 wiU probably still account for some 18,000 tons.

Nuclear Capacity by 1970

How does this revised and reduced program of uranium oxide purchases cope with anticipated de-maud? Last year, I indicated that the total installed nuclear capacity in electric plants in the Free Wor ld would probably he 20 million kilowatts in 1970. This st i l l looks today like a plausible goal. Even this quite sizeable amount of nuclear power wi l l be small i n comparison with the installed capacit}^ in electrical plants i n the Free Wor ld which wiH then total at least 500 million kilowatts. In addition to the Shippingport plant, several large nuclear power stations being built by ut i l i ty companies w i l l become operational this year, next year and i n 1962. Y o u know them and I wi l l not review them here. Pacif ic Gas & Electric and Southern California Edison are presently considering adding even larger nuclear plants of a size of 300,000 kilowatts each to their systems.

A very encouraging new development is that sucli large manufacturers as Westinghouse and General Electric are now wil l ing to guarantee the capital cost, the plant capability, aud thc fuel burn-up of new plants. This is extremely encouraging since it w i l l permit the ut i l i ty comi)auies to Imow with a much greater degree of certainty what the unclear power costs are going to be. These plants are expected to be f u l l y competitive over their lifetime, as unproved cores w i l l be insei'ted in the reactors over the years.

Reactor Program in U.S.

Each new unclear j)0wcr plant brings us close to the threshold of competitive atomic energy. W i t h the operating experience gained f rom our excellent nuclear power program here in the U . S., i t is pos-


sible that quite a few reactor concepts w i l l become competitive i n the high cost energy areas of the United States by 1965. The present budget of the A E C for the fiscal year 1960 allots more than $400 mill ion for the reactor program. This total includes $90 mill ion for thc government reactor program i n a number of reactor prototypes, some $20 mil l ion to penult the A E C to assist i n the civilian power construction program under cooperative arrangements with private and jjublic utilities, and the remainder of the appropriation goes to the naval propulsion reactors, the army power reactors, the aircraft and the missile i^ropulsion reactors.

W i t h such au intensive overall program, our country still definitely retains the lead i n its diversif ied reactor program, as we have the greatest number of prototype reactors i n operation or under development. Such a vast program of joint government and private effort augurs well for the achievement of competitive nuclear power in a few short years.

Studies on homogeneous reactors, i u which the fissionable material is either i n a solution or i n the form of a slurry^, have shown that the technical problems are greater than anticipated. A s a result, developmental work on this family of reactors has been slowed down considerably and further effort is placed on the heterogeneoiis reactors i n which the fissionable materials are i n the form of solid fuel elements. I t is l ikely that research work on an extensive scale on homogeneous reactors w i l l only be resumed after some reactors using solid fue l elements have begun to deliver economic power.

Organic-Moderated Reactor In 1959, the technological emphasis shifted to

wards the development of the organic-moderated reactor and the closed cycle gas-cooled concept to be built by Atomics International, a division of North American Aviation, and Ceneral Atomic, a division of General Dynamics, respectively. In August of last year, the A E C signed contracts with the rhi ladelphia Electric Co. and 54 associated utilities and General Dynamics Corp., authorizing the construction of an advanced high-temperature gas-cooled plant. This plant, which -\vill have a capacity of 40,000 kilowatts, is expected to be completed by the end of 1963.

In 1959 also, the A E C initiated a long range program to evolve effective thermal breeder reactors which would make f u l l use of the latent energ;^' of thorium. A s you are aware, thorium, unlike uranium, does not have a naturally fissionable isotope but, when bombarded with slow or thermal neutrons, thorium is transmuted into U-233 which is a fissionable mater ia l just as valuable as U-235. I hasten to add that such a program offers no competitive threat whatsoever to uranium for the foreseeable future, because i t w i l l take many years before U-233 is produced to fuel new reactor capacity on an important scale. Consolidated Edison's reactor at Indian Point near Peekskill, New York , to be completed i n 1961, w i l l make use of this principle, although it w i l l not be a breeder, i n that i t w i l l produce less U-233 than U-235 is consumed.

Uranium Transmuted into Plutonium On the subject of breeding, the Detroit reactor of

the Power Reactor Development Co., to be completed i n 1961, w i l l malce use of this principle. In such a reactor, the non-fissionable portion of natural uranium, i.e., U-238,^ w i l l be transmuted with fast neu-

30

Irons into plutonimn which is also a valuable fissioii-able material like U-235 or like U-233.

Although the true long-term future of atomic energy lies i n breeding, we should not imagine that breeder reactors of cither tyjm wiU compete with U-235 for many, many years to come. St i l l , the abundance of uranium for thc next decade should not preclude this nation f rom investigating the problems of breeding plutonium and U-233 as two additional fuels for the more distant future.

Superheated Steam Lowers Cost One way to lower the cost of electricity made from,

the atom is to use superheated steam, and particular emphasis is now being placed on this process. Reactors have been operated at rather conservative temperatures because of the danger of a hot spot in a reactor which might cause a meltdo'wn of one of the fue l elements and thus release radioactive fission products i n the cooling system. This has resulted in a thermodynamic efficiency of only about 25 per cent. Of course, this does not compare with the efficiency of 40 per cent (8,000 B T U ' s per kilowatthour) obtained in some of the most modern conventional plants using supercritical i^ressurcs and elevated temperatures.

A l l the principal companies are presently engaged i n the study of nuclear superheat. A n y increase iu the overall thermodynamic efficiency, and this is extremely important, wiU automatically result i n a proportional lengthening of the lifetime of the fuel elements i n terms of useful energy produced, while also i-educiug capital costs per kilowatt of installed capacity. General Dynamics promises efficiencies of at least 32 x>er cent i n their closed-cycle gas-cooled reactor concept now being developed. Undoubtedly, competitive atomic energy w i l l not be achieved without much higher efficiencies than we have at present.

Euratom Program Announced In thc international f ield, the six nations of the

European Atomic Energy Community (Euratom).—• Prance, West Germany, Italy, Belgium, the Netherlands aud Luxumbourg—had announced i n May 1957 an ambitious program calling for the constimction of a large amount—15 million kilowatts—of nuclear capacity by 1967. A more modest program was later decided upon calling for one mill ion kilowatts of nuclear capacity by 1962-3, employing reactor types developed in the U . S.

A deadline had been set for Oct. 20, 1959 for the submission of f i r m bids to construct atomic plants. It had been hoped that at least six projects would be presented, aud i t was a great disappointment to all that only two proposals were received, one for Italy and the other fo r Germany. To make matters even worse, the Italian project had actually been decided upon a year earlier and as fa r as the German reactor is concerned, that one is not yet a sure thing today. This state of affairs i n Europe results f rom the temporary coal surplus and the promise of oil f rom A l geria and Libya .

Energy Picture Comparable The energy picture in Europe is becoming com

parable to that of this country, and the earlier expectations that atomic energy would be competitive in Europe sooner than i n America are no longer valid. It looks now as though atomic energy wi l l become competitive i u Europe at just about the same time as it w i l l i n the U . S. The present Euratom program


is being reviewed and providing f lexibi l i ty is injected i n the timetable, it is probable that other utilities within the Euratom group wi l l probably decide on reactor construction.

The International Atomic Energy Agency, a specialized agency of the United Nations, was created in the f a l l of 1957 i n Vienna, Austria. It is now f u l l y operational and is doing excellent work i n counselling the underdeveloped nations i n preparing for the day when atomic energy wi l l become practical for them. Its primary role is to assist, guide and coordinate. Bilateral Agreements Signed

The United States has signed more than 40 bilateral agreements with other nations to assist i n their atomic research programs. Of course, this activity must precede the actual construction and operation of power reactors. I t is hoped that i n time these bilateral agreements w i l l be transferred to the International Atomic Energy Agency so that it w i l l become the ultimate depository for such agreements. Certainly it was the iutention of President Eisenhower through his "Atoms for Peace Program," which in turn led to thc creation of the Agency, to work through the Agency with the other nations of the world. Evidence of this is also found in the fact that this country has agreed to make available 5,000 kilograms of U-235 to the Agency at the A E C ' s price for domestic sales and to match the sum total of a l l amounts made available to the Agency by al l other nations up to Ju ly 1, 1960.

Encouragingly, thc United States and Russia recently pledged themselves to a closer cooperation within the Agency. Competitive Nuclear Power

Prom this vast deployment of engineering effort going into the reactor program, we are gradually inching towards the achievement of competitive nuclear power. I have indicated that by 1970 the Pree Wor ld should have some 20 mill ion kilowatts i n nuclear power stations. It could as well be 15 or 25 million. The exact figTire is uot too important. The important thing is to look forward to the day when atomic plants w i l l become competitive, at f i rs t in the high fuel cost areas in the technically advanced nations of the world. Should this occur.—as seems quite likely—-by 1965, i t w i l l s t i l l take a few more years before a substantial proportion of yearly additions to the installed capacity becomes nuclear.

FORWARD WITH MINING INDUSTRY

(Continued ff-om page 25)

tion to equalize market conditions which otherwise might get out of hand. There are those who arc urging the depletion of our B'ederal stockpile of minerals. Their calculations are based upon the theory that if wc get into an emergency it w i l l he of short l ife. The original five year estimates have been cut to three years and programs of procurement, such as manganese and tungsten, have been discontinued, much to the detriment of domestic producers.

Immediate Future Not Bright The overall prediction for thc mineral industry

for the immediate future is not bright. Anyone reading the recent issue of the 'Engineering and Mining Journal and studying carefully the analysis made of the different market conditions for the different min-

I do foresee, however, that the bum-up needs fo r the nuclear capacity i n operation by 1970 for electrici ty and the many other peaceful uses outside of electricity, plus the inventory needs of new capacity and the "pipeline" requirements leading to and f rom the reactors, ^vill absorb the f u l l output of the mills at the presently contemplated levels i n this country.

In the meantime, I believe thc conclusion is inescapable that there is going to be a temporary gap between supply aud demand of uranium iu this decade, even after taking into account the stretch-out of the Canadian program and the application of atomic energy other than for electricity.

Market Assured Through 1966 Thc principal thing to bear i n mind is that the

American mining and mil l ing industry is assured of a market unti l the end of 1966. That means almost seven years to go. While I am sure that no one is i u a position to gTiarantee what w i l l happen to uranium, or to any other metal for that matter by 1966, I am personally confident that we wi l l then be f a i r ly close to the point where a Pree Wor ld market for uranium w i l l exist. I am also convinced that although exploration for new ore is not exactly encouraged at the present time, thc uranium miners w i l l f i n d it advantageous to resume exploration on a much more intensive scale before 1966.

General Conclusions What conclusion may we draw f rom all tliis? The domestic uranium industry is in sound condi

tion and it is assured of a market for the next seven years. While no one can guarantee exactly when atomic energy m i l become competitive, it appears that i n the technically advanced nations i t may begin to be i n some areas by 1965 and i n many more by 1970. Between now and 1966 and perhaps for a few more years, some stockpiling of uranium may be necessary. This is perhaps uot so bad after all because, when atomic energy does become competitive, there probably w i l l be a marked snowballing effect, and since ore exploration and new m i l l construction may take some time, the existence of a moderate stockpile in the early years may be a good thing. May I therefore suggest that yon relax and be patient i n this twilight period. Certainly you have played your part well and there is nothing more you can do untd other actors on the atomic scene play their part—and believe me, they are doing their very best.

erals cannot conclude otherwise. However, what I am proposing here is a clear-cut look at the long-time mineral supply and demand picture. It is my honest judgment that the United States Government should do everything possible to keep the mines active and this includes the small mines as well as the large mines.

Policies Should Encourage Production Policies should be adopted which encourage pro

duction rather than discourage prodxiction. Mining know-how should not be lost to our economy. Migration of miners f rom our mines is a dangerous precedent. It is up to tho Mining Associations of the West to fight and to fight hard for proper recognition for the domestic mining industry.

I t is my prediction that with the help of mining people everywhere, eventually the domestic mining industry wi l l again take its proper place i n the economy of the nation.


Radioisotopes In the

Mineral Industry^

By FRED L SMITH

FRED L. SMITH

E-adioisotopes }iave a good potential i n the mineral industry as tools to be nsed in, cutting costs, improv-uig product, and permitting the mining engineer aud metallurgist to do things i n their work that would be diliiicult or impossible to do hy other means. Eadio-isotopes also have definite characteristics, problems and hazards of their own and are by no means a cure-all for every problem.

This paper w i l l point ont some of the uses to which radioisotopes have been put, some of the uses which they w i l l have i n the future. It w i l l also discuss some of the things that must be done before the radioisotopes can be put to as widespread use as their ultimate potential justifies.

A s a more or less formal definition, isotopes are atoms of one element that d i f fe r as to the munber of neutrons i n the nucleus and thus i u the atomic weight hut have all the other chemical characteristics of the element. One way to visualize a radioisotope is to consider it as an atom of an element that behaves chemically just like ordinary atoms of the element except that i t is radioactive and decaj'-s and emits a particular k ind of radiation that is in effect a specific label for that atom; shows where it is and what it is doing.

THE AUTHOR Fred L. Smith joined the Colorado School of Mines

Research Foundation in 1950 and has served as manager of its Mining Division since 1955.

Mr. Smith obtained a B.S. degree in -physics from the California Institute of Technology in 1938. Since his graduation he has had experience in geophysical surveys, undergrotmd and open pit mine operations, tunnel driving and concreting, cost evaluations and feasibility studies ivith. such companies as Ibex Mining Corp., Union Carbide Corp., U. S. Smelting, Eefining mid Mining Co., Newmont Mining Co., Brown-Root Construction Co., and Parker and Vmiderwilt, Consulting Geologists.

He is a member of the AmeHcan Institute of Mining, Metallurgical and Petroleum Engineers, American Association for the Advancement of Science, Na-tiorud Society of Professional Engineers, A.mencmi Mining Congress, and Colorado Scientific Society.

Eadioisotopes for use in industry may be made available f rom a f ixed source, a movable source, or as tracers placed in the material to be measured. The various uses to which the different sources are most readily applicable are shown in Fig. 1.

A l l uses of radioisotopes stem from one of the three ways in which the isotopes and their assoeiated radiation behave.

First—-'R&dmtAow affects materials. :Seco?itZ—Materials affect radiation. Third—Eadiation traces and labels materials. Examples of the first application, i.e., the effect

of radiation, on matter, are the elimination of static charge on a belt di-ive, or âilcanizing rubber without use of sulfur, aud improving the strength of metals by modifying the crystal structure.

Thc second, or "materials affecting radiation" moves more into the f ie ld of mineral iadustry applications. Instrumentation, such as gamma density gages, thickness gages, hquid level gages, and other applications are instances where the isotope and its associated counting equipment acts as a measuring instrument resulting from absorption and scattering of radiation.

The third use, "radiation traces and labels materials," is seen where isotopes are used for determining residence times in digestors, thickeners, .furnaces; in


determining the efficiency of mixing, measuruig the gas flow through sinter beds and monitoring tailings or discharge of other wastes.

In the laboratory, radioisotopes can be used to test the suitability of analytical methods to determine vapor pressures, to make quantitative deteiminations and to follow chemical reactions.

The Canadian Department of Mines has used radioantimony to tag dynamite so that missed holes and unexploded powder can be located. Eadioisotopes have been used to keep track of underground mine fires and to deteiniiiie the flow patterns of underground water.

Probing d r i l l holes with Geiger and scintillation counters is an example of use i n practical geologic exploration and neutron logging to show water or oil content of strata. Isotopes have been used to measure belt speeds, rope speed in hoisting and to prevent overwind. The following series of slides show how some of these applications work:

which convert the natural atoms into radioisotopes. Each individual isotope gives off a gamma or beta particle that has a characteristic energy. It is possible to identify the elements and determine their concentrations "by gamma ray spectrometry. This means that a mixture of radioisotopes can be analyzed i n much the same manner as a mixture of ordinarj'-elements can be identified by an optical or x-ray fluorescence spectrograph.

In the not too distant future it w i l l be possible to continually analyze material i u the m i l l circuit and control the operating variables so that they are always at an optimum condition for thc material i n a pai'ticular stage of the process. Two things should be done to make continual neutron activation possible. The f i rs t is developing a good, cheap, reliable neutron source that gives a sufficient number of neutrons per second to bombard the materials. The second thing that must be done is to develop large volume counters that can determine the k ind and amount of radioisotopes present as a result of the neutron activation. This -wiU enable counting to be made on very low radiation levels and with very short half-l ife materials so that by the time the finished product is shipped to the consumer, no radioactivity w i l l be left in it. Both of these requirements are under intensive research and development and should be available i n a few years.

A Landmark The Denver IVIiHiing Club

Survivor of the ups and downs of the mining industry for over half a century.

GUY L V. EMERSON

Back i n the nineties when gold mining was the j^rincipal industry in Colorado, a group of pioneer giants tu industry, comprising the (ôlorado Min ing Stock Exchange, purchased thc ground then described as "Lots 1, 2, 3 & 4, East Denver" for $160,000, On this groruid, now at 15th and Arapahoe Streets, was erected i n 1890 and 1891, the Mining Exchange Bu i ld ing, on top of which stands the statue of the old prospector, pick in one hand and gold brick i n the other, master of all he surveys. He has stood guard over the surrounding area for all these 70 years, a forgotten man, representing an almost forgotten industry—gold urining—in the state of Colorado. This sj^lendid old building is now the home of the Mining Record, one of the oldest mining weeklies i u this country.

Subscribers to the f u n d for the cost of the building were such men as John Evans, first governor of Colorado; C, B , Kountze, i^rominent banker and founder of the present Colorado National Bank; Henry C. Brown, who built the Brown Palace Hotel, and "W". N . B y ers, ovuier and publisher of the Eocky Mountain News. Other prominent and successful citizens of those early days who particij>ated in the activities were David H . Moffat, banker and builder of the Moffat Railroad; J . A¥. Nessmith, president, Colorado Iron Works; Walter S. Cheesman, c a p i t a l i s t ; Dennis Sheedy, president, Denver D r y Goods Co.; II. A . W . Tabor; John Harvey of Leadville, and D, R. C. Brown of Aspen. W i t h the cooperation of this group, the Min ing Exchange Bui ld ing was financed, erected, and opened with much publicity at 10 a.m. Wednesday, Nov. 18, 1891.

AVhen completed, thc Central Savings Bank, now Central Bank and Trust Co., occupied the corner ground floor, while the Colorado Min ing Stock E x change used the entire second floor. Beaut i ful paneled walls framed a scene of feverish activity as the exchange handled sales for clients and speculators, both local and throughout the United States. Many important individuals aud corporations had offices in the building, including such active mine owners and operators as J . 0. A . Carper, George CoUins, Shrive Chase, John T. Barnctt, Charles Chase, Benjamin Briscoe, Buckley Wells, Ered Carstaphen, Governors Jesse McDonald, Wi l l i am E . Sweet, and Oliver H . Shoup; E z r a Dickemian, Stephen lonides, Henry Sanderson, Charles N . Bel l , Ralph McFann, Charles Nc\iuneyer, and Charles W . Henderson of the U . S. Bureau of Mines.

These men gathered for lunch to discuss thc mining events of the day at different old-time restaurants like Hurlburt 's Dairj'" Lunch, The Home Dairy, Tor-

toni's aud thc Manhattan. Out of these informal gatherings grew thc Demmer Mining Clnb. E a r l y in its history luncheons were held at the Daniels aud Fisher Tearoom, thc Edelweiss and the Denver Chamber of Commerce restaurant. About 20 years ago, the Club moved to the Denver D r y Goods Tea Room for its luncheons held there every Wednesday, Average attendance is about 50 members and guests.

Before mining went into a decline, thc main subjects for discussion at these luucheon-meetings were mining aud mining news from different areas of the state—reports by prospectors and mining men on new discoveries and activities in mining. A t present these luncheon-meetiugs are enlivened by good tallcs on miniug and mil l ing and also other subjects of general interest. A recent sj>eaker at one of these luncheons—• Dr, Jolm W Vanderwilt, president of the Colorado School of Mines-—drew a record number of members.

Strictly a luncheon club, the Denver Minmg Club welcomes anyone remotely connected or indirectly associated with the mining Industry. There has never been any membership fee or dues. Membei's merely pay their own luncheon checks and those of their guests.

A f t e r hearing the story of the proposed "Rush to the Rockies" celebration which was scheduled for 1959, the members agreed to rent the old stock exchange room i n the Mining Echange Bui ld ing and put in a display of ores, concentrates, mining machinery, antiques, maps, pictures and books. Accordingly "The H a l l of Min ing Progress" was opened to the public i n January 1959. A fine display of moi'e than 300 items was accumulated through the efforts and cooperation of mining and machinery companies and their representatives. A n " O l d Timer," A . Roy Wicker, supervised the display, and members, on a voluntary basis, kept the display open throughout the Centennial celebration. More than 10,000 visitors saw this fine display i u eight months. This was made possible hy voluntary contributions f rom members of the Mining Club, for no support was given by the state, county or city.

The Denver Muring Clnb maintains an office in Room 202, Midland Savings Bui lding. Current officers of the club are: President, Guy L . V . Emerson, president, Treasure Mountain Gold Mining Co.; Vice-President, Kenneth Herrmau, Union Supply Co., Denver; Secretary, Ar thur E . Mayhem, newspaperman and miue owner; Treasm-er, Wi l l i am B . Cramer, former associate professor of metallurgy, Colorado School of Mines, and now a considting metallurgist iu Denver.


Underground Blasting Experiments

Using A m m o n i u m Nitrate In Small Diameter Holes^

By J . 0 . MILMOE and T. R. YOUNG, '52

Introduction

During the past year the Colorado School of Mines R e s e a r c h Foundation has been investigating the use of N - I V aminonium nitrate as au underground blasting agent.

The purpose of this investigation was to determine the feasibili ty of ammonium nitrate fue l oil mixtures fo r underground blasting. A t the start of these tests, little information was available on the use of ammonium nitrate iu small diameter, 1% to 2 inch, blast holes underground. The principal aim was to determine whether ammonium nitrate fuel oil mixtures, properly boostered, could he nsed i n place of explosives now being used for hard rock mining.

The data, given in this paper, were obtainecl i n au 8 by 8 foot dr i f t at the Colorado School of mines experimental miue i n Idaho Springs, Colo. The dr i f t was driven at a right angle to the main tunnel, about 800 feet f rom the portal. The rock was a hard, granite gneiss of the Idaho Springs formation; little variation i n the rock was noted during the test work. The dr i f t was approximately parallel to the structure. The only water pi'csent came from dri l l ing the round aud wetting-down the muck pile. The conditions were ideal for the use of ammonium nitrate.

Test Procedure

The a m m o n i u m nitrate was mixed with six per cent, by weight, of No. 2 fuel oil i u a small cement

mixer, and then hand loaded into either plain paper tamping bags 114-inch diameter, or li/4-iiicli-diameter 1.5-mil-thick polyethylene bags. F o r other than test scale work, a cheaper and quicker method of loading the bags would have to be found. There was no noticeable difference between the paper and polyethylene bags i n loading, tamping or f i r i ng the holes. The age of the mixture when used varied f rom five to forty days, with no noticeable effect due to this factor. A pneumatic placement device is available for loading the dr i l l holes, but was uot used during this work.

A five hole btirn cut was drilled for rounds less than five feet depth (see Figure 1) and an extra unloaded center hole was drilled for deeper rounds. The number of holes per round varied f rom 24 to 29, depending on the depth of tbe round and the hole diameter. The f i rs t rounds were drilled with, 2 /4 inch bits. Hole diameter was later successfully reduced to 1% inch. Both steel and tungsten carbide bits were used for dri l l ing.

Since ammonium nitrate fue l oil mixtures are not cap sensitive, thc mixture must be detonated with a cap sensitive explosive, referred to as the booster. I n all the rounds shot except one, the booster was either a half or a f u l l stick of DuPont Gelex 2, 45 per cent bulk strength with a No. 6 electric blasting cap. Both rcgrdar aud mi l l i second delay caps were used. The booster was placed at either the bottom or the collar of the hole. The bottom of the hole boosteriug

proved to be the more successful method for the 8 by 8 foot dr i f t .

Test Results

In considering the results of the test rounds, a l l references to the explosive mixture wi l l be made by using the term "mixture" rather than the cumbersome f u l l name of anunonnnn nitrate fuel oil mixture. Results of thc test rounds are recorded separately by number.

Test Round No. I The f i rs t round shot was five

feet deep with 2^4 inch holes. The holes were boostered with a half stick of Gclex 2, placed at the bottom of thc hole wuth a regular delay cap. The round was loaded with 92 pounds of the mixture; the combined weight of the mixture and Gelex was slightly over 100 pounds. This round pulled to the bottom of the d r i l l holes with uo bootlegs.

higher than the average for the rounds f i red i n the test program.

Test Round No. 2

Another f i v e - h o l e burn, f ive feet deep with 2^4 inch holes, was boostered with 175 grain plastic-covered Ensign Bickford Primacord. Thc prunacord was stretched the length of the hole with a large knot at the bottom. The paper bags of m i x t u r e were f i rmly tamped into each hole; approximately 70 pounds of the mixture were used for the round. Regular delay caps were attached to the prunacord at the collar of the holes, since it is not safe to tamp the ammonium nitrate on top of an unprotected cap.

"When this round was shot, ten holes misfired. The primacortl was severed between the cap and the mixture because of a rock slip 12 to 18 inches behind the original face. Because of this diff icul ty , primacord was not used to booster any other rounds. Perhaps this failure could be eliminated i f the cap could be placed at the bottom of the hole.

holes. Thc paper bags of mixture were f i n u l y tamped into the holes with a booster slit and tamped at the collar. A total of 60 pounds of the mixture, or 0.186 pounds per cubic foot of broken rock, was used for this round. Including the dynamite booster the powder factor is 0.21 pounds iier cubic foot or 13.4 pounds per foot of advance. Pour t r im holes misfired because the booster was blown out by the blast f rom the adjacent hole. Good fi'ag-mentation was obtained, even with the misfired holes. Test Round No. 4

Another round was collar-boost-ered with a f u l l stick of Gelex 2, f i red with millisecond delay caps. The round was a six-hole burn, six and one-half feet deep, drilled with 1^2 inch tungsten carbide bits. Several cut and t r im holes failed to detonate completely, causing the round to bootleg three feet. It seemed certain that all the boosters detonated i n place, as the faces of the undetouated plastic bags were blackened. Thc reason for this faihire is uot known.

F r o m the results obtained with collar boosteriug, it appears that this method is not satisfactory for a d r i f t of this size. F o r larger openings, where the distance between holes is great enough to prevent the primer from, being shot out by adjacent holes, satisfactory results may be obtained. Var iations in density of the explosive column i n these hand-loaded holes may also have contributed to the problem. International Mineral's Carlsbad potash operation has been using collar boostered 1% inch holes successfully; however, the holes are farther apart, the ore is less hard, and pneumatic placement of the mixture provides an uninterrupted column of unifonn density.

In the 8 by 8 foot dr if t , bottom hole boosteriug yielded more encouraging results. In addition to the f i rs t round mentioned, several other rounds were shot using the booster i n thc bottom of the hole.

The last round f i red in these tests was seven feet deep; drilled with 1 ^ inch tungsten carbide bits using a six hole burn to cut with the two middle holes not loaded. Slightly less than four pounds of the mixture was loaded and tamped in each hole after placing the booster, a f u l l stick of Gelex 2 and mil l i second cap, at the bottom of the hole. The ninety-two pounds of mixture used i n thc round was bagged i n 1% inch diameter polyethylene bags. This round prdled six feet, three inches of its seven foot depth with very good fragmentation.

Fume production under the conditions at the experimental miue appeared to present no se r ious problem; and good air was encountered in thc dr i f t a short time after blasting, the dr i f t being reentered i n as little as 15 minutes. No special provisions were made to ventilate the d r i f t because of the short distance from the main tunnel , which is also the main air course.

However, since little is known about the fumes of ammonium nitrate, an investigation of tho fume characteristics of this explosive is now underway. A t the present time there is no infonnation available for publication. U n t i l the iuformation on the fume production is published, ex t reme c a u t i o n should be exercised when using this explosive.

There has been no noticeable difference between the full-stick and the half-stick boosters. The f u l l -stick was used because of the length of thc delay caps. The short half-stick for bottom hole boosteriug c o n s t i t u t e d a safety hazard.

The performance of thc ammonium nitrate explosive mixture iu this investigation definitely indicates the practicability of the explosive for use i n most underground hard rock blasting operations. Wi th proper mixing, packaging, loading, and boosteriug, the mixture can be shot in inch diameter holes with excellent fragmentation. The properly packaged mixture can be handled with greater safety than conventional explosives due to its relative insensitivity.

There are three problems which must be solved before anmionium nitrate w i l l be freely accepted as a general underground exp los ive . The first is fume production which has been discussed. The second problem occurs i f excessive moisture is present with its consequent reduction of the explosive's effectiveness. Since most underground operations are humid, the aimno-uium nitrate eamiot be stored un-dei'gi'ound for any length of time.

• Figure 7B, After. Evenly distributed muck pile typicai of millisecond delay cap timing.

The third problem involves thc diff icul ty of loading a vertical up-hole as thc loose prillecl 'ammonium n i trate fuel oil mixture w i l l f a l l out before it can be stemmed i n place in a homogeneous column.

Even before these problems are solved, there are applications i n imderground hard-rock operations where thc mixture may be used readily. Due to its relatively low-cost, a saving may be realized wherever this ammonium nitrate fuel oil explosive mixture is properly employed.

Tltanmni and titanium alloys have been the object of much study in recent years. Part icularly in aircraft applications, the strength-to-weight ratio of titanium alloys and their high resistance to chemical attack are desirable properties which encouraged the titanium industry. Subsequent research indicated that most titanium alloys did not measure up to earl^ expectations with regard to high temperatui-e coi-rosion. In particular titanium alloys have a strong' tendency to absorb interstitial unpurities at high temperatures. Nitrogen, oxygen and hydrogen are among these interstitials which greatly change the mechanical properties of titanium. Hydrogen em-brittlement is a problem which has received much attention.

A brief review of the metallurgy of titanium is required i n order to understand the nature of the current investigation on the titanium-oxygeu-liydro-gen system. Pure titanium exists in two allotropic crystalline forms—a hexagonal-close packed ( H C P ) structure: «:-titanium; and a body-centered cubic modification ( B C C ) ^-titanium. The cc form is stable up to 882.2°C and the /? form up to the melting point. Upon heating, a specimen of pure titanium undergoes expansion which is a continuous function of temperature—but at 882.2°C a sudden expansion occurs i u going f rom cc to 8 forms since the body-centered cubic structure is not as dense as the hexagonal close packed. Thc increase i n volume is approximately 5.5 per cent. This iuci'ease in volume affords a direct means of stud^dng phase changes i n this system. However, other properties w i l l also undergo a discontinuity, e.g. resistivity, lattice parameter.

Another means of effecting a change from one crystal structure to another is by the introduction o:l: alloying agents. The constitution diagram of the titanium-hydrogen is given i n Figure 1. I f a specimen of pure titanium is heated to 800°C i n an evacuated vessel, the stable crystalline form is the cc - H C P form. I f small quantities of hydrogen are introduced, it is found that the hydrogen molecule wiU dissociate and dissolve monatomically in thc interstices of the H C P structure.

' Tills article is a. prelim in ary reyiort on Coloracio School oi limes Foun-(liitioii Project No. 5910.


There are two different kinds of interstices possible for solution of small atoms within the a -titanium lattice. One set is termed tetrahcdral i n that each interstitial atom is surrounded by four nearest neighboring titanium atoms. The second type is called octahedral i u the sites being surrounded by eight nearest neighbors. Hydrogen prefers the tetrahcdral site. A s more hydrogen is added the structure may expand slightly to accommodate the additional atoms (or i f the interatomic forces are highly attractive the lattice may even shrink), Long before saturation or complete f i l l i n g of the available tetrahedral interstices, the energy of the crystal modification suddenly luses above that of the fS modification and some j8-titanium starts to appear with increasing hydrogen addition. Prom the constitution diagram this point corresponds to a hydrogen content of about 3 atomic per cent at 800°C.

The bodj'-centered lattice of /3-titanium has one type of interstice—^the tetrahedral. Interstitial atoms of hydrogen diffuse to these locations. Increasing the hydrogen content only increases the relative proportion of ^ to oc: i n the two phase mixture. The overall density of the alloy undergoes a sudden increase with the appearance of the p phase, corresponding to discontinuity in slope of a density-composition plot.

F ina l ly when the over-all composition reaches 7 atomic per cent' hydrogen, the cc phase has transformed completed to the ^ by redistribution of atoms by a diffusion mechanism. The B C C lattice may now expand or shrink with further hydrogen additions.

A schematic plot of lattice parameter, density or dilation is given i u Figure 2 corresponding to the above thought experiment. The hydrogen absorption is completely reversible in that evacuation wi l l remove the hydrogen i f thc temperature is sufficiently high to allow for an appreciable diffusion rate. A t temperatures above 400°C the following reaction is reversible

system- is presented i n Figure 3. Note the large solubi l i ty of oxygen i n cc -titanium, up to 33 atomic per cent. A comparison of the two constitution diagrams (Figure 1 and Figure 3) shows that the additions of oxygen tend to stabilize cc -titanium, whereas additions of hydrogen tend to stabilize ^-titanium.

Oxygen also dissolves monatomically i n titanium but occupies the octahedral interstices of the o: phase.

The absorption of oxygen is not reversible since the equilibrium pressure of oxygen i n titanium for a given composition and temperature is always very low. The di f fus ivi ty of oxygen is several orders of magnitude lower than the dif fus ivi ty of hydrogen.

A recent investigation of the titanium-rich corner of the T i - O - H system at 800°C has led to a tentative isothermal section which appears schematically in Figure 4. The procedure for determination of this phase diagram was to plot square root of hydrogen pressure against mole fraction hydrogen for various titanium-oxygen alloys at constant temperature. The

hydrogen pressure underwent discontuinities i n slope with hydrogen content when a phase appeared or disappeared. These plots were sufficient to delineate the cc to cc - j - /5 phase honndary clearly, but some d i f f icu l ty was e n c o u n t e r e d in determining thc «: -|- /3 to /? boundary. The present investigation was proposed as a means of studjung the cc + /3 to /5 transformation i n more detail.

The current study is outlined as follows: A titanium specimen is introduced into a compartment of a differential dilatometer. This instrument measures change i n length of a specimen relative to a standard. Currently a Chevenard optical dilatometer is being nsed. This instrument can magnify expansion by a factor of about 400 to one. The specimen compartment is surrounded by a quartz envelope which can be evacuated by a diffusion pump circuit.

42

Around the envelope is a fnraiace and temperature controller. Thermocouples adjacent to the specimen enable its temperature to be measured accurately.

The vacuum system is connected to a modified Sievert's apparatus, Figure 5. This system enables measured quantities of hydrogen to be introduced into the specimen compartment. The apparatus is used to study the following parameters:

(1) specimen temperature (predetermined and controlled);

(2) specimen hydrogen content (predetermined and controlled);

(3) hydrogen pressure (a dependent variable); (4) specimen expansion (a dependent variable). The over-all object of an experimental run is to

determine the location of the boundaries of the a: -|- /S f ie ld i u the titanium-oxygen-hydrogen system.

T H E MINES MAGAZiNE MAY, 1960

A typical experiment is described as follows: A weighed speciment of high puritj^ titanium is arc melted with a measured quantity of titanium dioxide po^^'der to form a homogeneous alloy of a given oxygen-to-titanium molal ratio. The specimen is introduced into the dilatometer compai'tmeut which is then evacuated to a pressure of about 10"^ mm. of m.ercur\'. The specimen is heated u.uder vacuum to a given temperature T i and annealed. Let T j be below the cc to /3 transformation for this alloy so that the crystal form is H C P .

"With temperature maintained at T i , and molal ratio of oxj'gen to titanium maintained constant, a small measured quantity of hydrogen is added to the specimen, and the increase or decrease in length of the sx)ecimen is observed as a function of time. Eventually when no change is observed with time, the value of increase in length and equilibrium pressure is recorded. This period is of the order of only a few minutes in a single phase alloy where the rate controlling step is the diffusion of hydrogen.

A second quantity of hydrogen is admitted and a second reading of length and pressure is recorded. (The reversibility of the hydrogen absorption can be checked by removing hydrogen to reestablish the f i rs t point). A series of hydrogen additions is made unt i l a discontinuity appears ui slope of a plot of differential Icugth vs. atom per cent hydrogen and concurrently a discontinuity i n slope in a plot of equilibrium pressure hydrogen vs. atom per cent hydro

gen. These plots are analogous to Figure 2 for the T i - H binary. The introduction of oxygen into the specimen causes some increasing complications.

A s the experiment continues, it is found that as hydrogen is added to the two phase mixture of cc - ] - j3 time lapse before equilibrium becomes progressively longer. The reason for this is the necessity for oxygen to redistribute itself between the two phases over a diffusion path which is a function of the grain size. The rate of diffusion of oxygen is much slower than that of hydrogen. A s hydrogen additions continue! the cc phase disappears f inal ly and the alloy is again singie phase now in the ^ form. The compositions corresponding to the two discontinuities i n slope, mark the limits of the two phase region for the particular temperature and tlie particular oxygen to titanium molal ratio. The results of a given run are then reported on a ternary isothermal section.

The unique feature of these sets of experiments w i l l be the isothermal study of expansion as a function of continuously varying composition, which is possible by virtue of the ease in which hydrogen content may be varied. Eventually i t is anticipated that concurrent high temperature x-ray lattice parameter measurements may be made. The major d i f f i culty which w i l l be encountered is the tendency of the slope of the expansion vs. composition curves to round off because of the sluggish redistribution of oxygen. No comment can he made at this time on this phenomenon ruitil further data are collected.

CSM Experimental Mine

Used for Instrucfion In Explosives

By ROBERT DYMENT

Practical experience in drilling and blasting procedures provided for Colorado Schooi cf Mines Students.

THE AUTHOR

Robert G. Dyment, a graduate of Rochester Institute of Technology, was a former associate editor for three iveekly ncivspapers published in Neiv Yorlc state.

For the past .six years he has been a field-editor and p 1-0fessional ivriter for many of the country's leading business, technical mid industrial magazines, specializing in construction and engineering articles.

• Blasting technique; Students utilize equipnnent in drilling and blasting a raise.

* This article appears here with the permission of TlIK EXPLOSIVES ENGINEER in which it was first publislied in the January-February 1060 issue.

Colorado's history is bright with mineral wealth and tales of prospectors who climbed and clawed their way among the rocky crags and valleys to find the elusive mineral riches or spend themselves in a lifetime of fadure. Todaj^, in Colorado, great mines are producing, ut i l izing the finest mining methods Imown. Their output has made "Colorado" another name for "mineral" among mining engineers the world over.

Except for the foresight of the Colorado School of Mines, the Edgar Mine at Idaho Springs might be a ghost mine, stripped of a half mil l ion dollars in ore. Bu t as a training laboratory for future engineers, the Edgar Mine is still a producer, st i l l contributing wealth, not i n ore, but i n rich and valuable experience for the men being trained there to exploit the mineral deposits of the world.

The Edgar Mine has been leased for 99 yeai's by the Colorado School of Mines for undergraduate work in miuing which cannot be taught in the classrooms. Work carried on there includes mine surveying, mineral land surveying, stoping, drif t ing, blasting, and the general mechanical engineering of mines. Another important purpose of the mine is to provide a place for mine research and experiments, covering all types of mining studies for further development and increased efficiency.

Mine Leased for Surveying

Dr . James TJnderhill, who came to the school i n 1919, is primari ly responsible for the acquisition of the Edgar Mine. A t that time, mine smweyiug was bemg conducted at the Stanley Mine at Idaho Springs. Its shutdown precipitated the need for another property, and the Edgar was ideal for a l l intended purposes. The Colorado State Legislature appropriated $20,000 for buildings and the repair of workings, and a long-term lease was obtained f rom the North American Mining Company of Denver. A l l of the upper workings were leased by the Colorado School of Mmes, and provision also was made for thc lower portions of the miue and of the B i g Five tunnel that extends under aud beyond thc mine for a distance of 8,000 ft . Development by the North American Min ing Company below the B i g Five tunnel went on during the 1930's.


• Machinery: A jumbo carriage is one of the machines mining students study during mining engineering practices.

• Surveying: One of the vital portions of the mining engineering laboratory courses taught at the Edgar Mine Is mine surveying.

• Cores: Students extract core samples from the drill steei of a Joy machine.


Mine surveying was conducted there exclusively by thc school f rom 1921 to 1932. In 1927, the Edgar shaft was cleaned down to the surface. The year 1935 saw the advent of actual mining operations by the school when the first compressor was purchased. That year was a banner year, as i t initiated an expansion of the facilities available. Over the past 32 years the Colorado School of Mines has expended an estunated $100,000 on labor, supplies, and ecpiipment.

The school's experimental mine has been available for industrial research since its opening. Gardner-Denver, which cooperated i n the installation of the first compressor, has been using the mine continuously since 1935 for its d r i l l testing. Three Claims Purchased

Laud at the base of the h i l l road leading to thc mine was acquired i n 1921, when it was purchased as lots within thc city limits of Idaho Springs. In 1949, under the administration of President Ben Parker, the school purchased three claims f rom thc North American Min ing Company. These three—the Goodyear, the Sunnyside, and the Newton—^were obtained for the sum of $5,000; the present machine shop, change house, and portal aro on this land.

The Colorado School of Mines follows manufacturers' recommended procedures for use of explosives and training of students i n explosives safety. Both experimental and regular dr i l l ing patterns are used.

The vein-type material i n the experimental mine contains gold, silver, lead, copper, and zinc. The wall-rock is granite. Blasting is performed on both crosscuts and veins.

Dr i l l s used are Gardner-Denver, Cleveland, Joy, and Ingersoll-Kand. The types of dril ls arc drifter, jack-leg, stoper, and jackhammer. Jumbo carriages also are used. D r i l l steel varies i n size f rom % to 1% in., including 1 and 1%-in, sizes. Detachable bits of tungsten carbide, Cleveland throw-away bits, and standard jack bits also are used. Sectional d r i l l steel i n lengths of 2, 4, 6 ft., and 8 f t . 4 in. is used for long holes.

There are two air compressors used i n the experimental mine. Both are G ardner-Denvers, one 600 c.f .m. and the other 900 c.f.m.

Diameter, depth, aud spacings of d r i l l holes vary i n some cases, but, predominantly, are 1^/^-in. holes, 6 to 8 ft . in depth, with spacing of approximately 18 in.

Hercules dynamites as well as other explosives are used. Common size is 1% by 8 in. iu 45% strength. Ordinarily, 3 lbs. of powder is used per yard of material in the solid. Stemming or tamping is not used except i n experimental rounds, predominantly i n advanced graduate courses.

Detonators utilized here are Hercules, i n addition to others, both short-period delay and regular delay types. The detonators are hooked electrically i n series or in series-parallel. They are fired with the existing 220-volt power supply. Pr imary blasts have proved very successful i n the experimental mine and secondary blasting is not used.

Blasted material is loaded with mucking machines, either Gardner-Denver or Eimco makes. The mater ia l is transported i n 37-cu. f t . Granby side-dump cars, pulled by a 5-ton Pl;s'mouth diesel locomotive. The blasted material is not processed, but disposed of on nearby muck piles.

Thc school teaches the use of explosives, dril l ing, and safety practices i n the proper classrooms—^before the students enter the mine.

Mine Laboratory Course Required Every student enrolled i n mining engineering

(there are now 153 undergraduate students and 15 graduate students) is required to take the mining engineering laboratory course. This course teaches the fundamental operations of underground mining, including dri l l ing, blasting, mechanical loading, haulage, and support practices as applied to drif t ing, raising, and winzing. Managerial aspects and the integration of unit operations also arc studied. The course is taught on 15 Saturdays and holidays during one semester, eight hours a day. P o r this amount of work, the student receives two semester hours of academic credit.

The classes average 35 men each semester, and either a mining instructor or a trained shift boss supervises each group of six students. Maynard Ayler , insti'uctor i n mining engineeiing, is in charge of the mine.

The experimental mine also is used for other purposes. Gardner-Denver and other mining machinery manufacturers use the mine to experiment with new machinery developments. The Colorado School of Mines Research Foundation uses the experimental mine as a laboratory for mining engineering research projects. Dur ing the summer months a certain portion of thc mine is open to tourists. Dur ing the summer of 1959, nearly 11,000 tourists made guided tours of the mine. These free tours are guided by several miuing students who staff the mine during the summer months.

Thus, the Colorado School of Mines ahd its experimental mine are playing an important part in supplying trained engineers and executives for the niining industry.

• Tourists: Visitors in the summer may tour the Edgar Mine guided by an instructor in mining engineering.

INCO Opens Highly Automated Mill In Sudbury Area of Canada

• View of operations of International Nickel Co. of Canada, Ltd., at the Levack Mill, in the Sudbury District of Ontario. Shown is the new mill and sand plant built at the mine shafts. Concentrates are shipped to Copper Chff and Coniston smeiters.

A new, highly automated ore mill ing plant has been opened by The International Nickel Co. of Canada, Ltd . , i n the Sudbury area of Ontario i n the latest step i n a continuing program to counter rising costs with increased production efficiency through technological advances.

The modern mil l , located at Inco's Levack Mine near Copper C l i f f , Out., and built at a cost of $12,-000,000, makes extensive use of instrumentation to permit centralized, and in some cases automatic, control of the crushing, grinding, flotation, and dewafering processes involved i n the production of concentrates f rom ore. A l l operations are controlled from centrally located instrument panels. Many recently developed techniques, such as the use of radioactive isotopes for making density measurements, have been incorporated into the new plant.

Additions and improvements Carried Out The mi l l is among additions and improvements

the Company is carrying out at its properties m the Sudbury area which, with the new nickel miniug project being developed at Thompson, Manitoba, w i l l raise Inco's nickel production capacity to 385,000,000 pounds per year by 1961. The Levack installation brings to three the number of ore mill ing plants operated by Inco at its nickel mines i n thc Sudbury area, thc free world's greatest source of nickel.

The Levack mi l l has a capacity of 6,000 tons of ore per day. Crushed ore f rom the Levack mine No. 2 Shaft is conveyed directly into a concrete silo-type bin with a live capacity of 3,000 tons. Two parallel conveyors feed the coarse ore to two 7-foot cone crushers which reduce it to minus three-quarters of au inch in size. The crushed ore is then conveyed to three


larg-e circular concrete bins with a total live capacity of 16,000 tons. A special screening process removes the wood chips en route. Automation is used to assist in this crushing operation.

Control from Central Instrument Pane! The crushers, crusher oi l pumps, screens, variable-

speed ore feeders aud conveyers are all operated and con trolled _ f rom a central instrument panel where lights indicate what equipment is i n service. The occurrence of trouble i n operation equipment sounds an alann on the control panel and gives a visual indication of the trouble. A u indicating and recording weightometer on the panel shows the tonnage of ore being crushed.

The two grinding units each consist of a 15-foot rod mil l , a 14-foot ball mi l l , and two cone classifiers. A central instrument panel controls the entire grinding operation. Weightometers automatically control and record thc rate at which ore is fed into the grinding units. Water addition to the rod mills is adjusted from the panel. In the cone classifiers the density of the overflow to flotation is measured and automatically controlled by radioactive isotope instruments which regulate the water addition to the classifiers.

Selective Flotation Process

The selective flotation process used produces a nickel concentrate, a copper concentrate aud a rock tailing. Flotation process variables such as pulp density, temperature aud alkalinity, are automaticaJly controlled by instruments located on a central panel.

The flotation concentrates are dewatercd in thickeners followed by vacuum filters. The operation of the thickeners and fhters is automatically continlled through instruments on a central panel on the fi l ter floor. The thickener underflow pumps and filtrate pumps are remotely operated f rom this panel. More than 30 railway cars of nickel and copper concentrates are shipped each day to thc Inco smelters at Copper C l i f f aud at nearby Coniston,

The flotation tailings are pumped 1,500 feet to the sand plant where approximately 85 per cent of the tailings are recovered as sand f i l l for use i n the mine. This f i l l material is sent by pipeline di-rectly into the mine.

• These five Dorr vacuum filters—four on nickel and one on copper —complete the job of dewafering the concentrates. The nickel filters are larger and can handle approximately 800 tons in a 24-hour period. Density and level of pulp feed in the filter are automatically controlled.

• Shown here is a portion of the flotation section of the new Levack Mill. The flotation section produces a nickel concentrate and a copper concentrate. There are 50 Denver and 50 Fagergren cells in the rougher-scavenger circuit and 40 Denver cells as separators, cleaners, and recleaners.

• Shown above is one of the three 60-foot Dorr tray thickeners in which the nickel concentrate is dewatered after flotation. A rotating rake slowly moves the thickened material to a discharge in the center of the tray, at which point it is 16 feet deep. The copper concentrate is also thickened.

An Analysis of the Proidlem

Mineral Engineering Education for the Future

By COL. WENDELL W. FERTIG, '51

Last month, we discussed a new approach to this problem offered by Charles Brinckerhoff, president of The Anaconda Co, Now, as a different facet of the same problem, we wi l l consider the welcoming address delivered by L>r. John W Vanderwilt, president, Colorado School of Mines, at the annual meeting of the American Institute of Mining, Metallurgical and PetTOleum Engineers, held i n New York City Feb. 12, 1960. There he spoke on thc subject: "The Real Problem—Mineral Engineering Manpower."

Jn considering this, the end product of Mineral Engineering Education, he said: " A s reported in a number of newspapers and magazine articles in recent months, there is no future for the mineral industries or for mining, metallurgy and petroleum engineering as a profession for young men entering college. These articles call attention to decreasing enrollments iu these fields and to jobless graduates as a basis for their dim view of the future.

"1 cannot agree with the picture that these stories present and fortunately not ail prospective students can accept them either."

Dr . Vauderwilt then went on to say that it is well to consider f i rs t those conditions that tend to obscure the hright and emphasize the dark side of the picture. From early 1957 and extending through most of 1959 our economy passed through a iêriod of adjustment. A s a result of many factors, some experienced engineers were unemployed and jobs were relatively scarce. The new engineering graduates iu 1958 and 1959 did not all have the choice of three to eight job offers as i n previous 3êars; i n fact a few had no job offers at all . Most employers regarded this as a return to normal conditions and were able to exercise a selective choice iu hiring. Even i n this more normal situation, all of the graduates who did not cuter thc mili tary service or continue i n graduate work were placed, lutei-views and inquiries f rom Irrespective employers indicate that the outlook for the graduate of 1960 w i l l be as good, i f not better, thai! for 1959.

The cause for concern is not that a few graduates had d i f f icu l ty i n f inding jobs, but that the total undergraduate enrollment i n mineral engineering in the United States has dropped for the second consecutive year. The cause for this decrease is not def

initely known, but many believe that it is due to the depressed state of thc mineral industries. A l l engineering fields have experienced similar decreases but to a lesser degree. This has been i n the face of steady increases in the number of students enrolled in all non-technical fields of higher education. F rom this it is concluded that the decreases in mineral enrollment are related (1) to the general economic readjustments that have been taking place, and (2) to competition coming from, new demands for engineering talent in the rapidly developing fields of nuclear energy, oceanography, electronics and instrumentation, space propulsion, aud others.

Now that is the darker side of the picture, .said Dr . Vanderwilt, and here is the brighter side. I n its December 1959 report on "Demand for Engineers," thc Engineering Manpower Commission of the E n gineers Joint Council reports projected increases in the demand for new engineering graduates as follows:

1959 1960 1963 1966 Min iug Engineers 8.9% 10.6% 14.9% 20.7%

Thc study did not include projected demands for graduates i n the fields of metallurgy, geology or geophysics. Although statistics of this k ind represent a sampling whose reliability may be questioned, yet 19 industrial areas were represented and all agreed that the demand would continue to increase. Other evidence that supports the increases i n demand are the growing population and expanding economy that wil l require greater quantities of mineral raw material of all kinds. Although one segment of the economy may be operating in a slow period, the others are operating in, a more favorable climate. The net result, based on past experience, is that tliei'c w i l l be increases in the consumption of metals and minerals, aud a demand for an even greater variety of materials than ever before.

To meet these growing requirements there must be more and more exploration and development of thc mineral resources of the world. More research wi l l he required to improve recovery methods, and to improve refining operations. Men with au engineering background and a talent for administration wi l l be needed to solve increasingly complicated management problems. Thus in three major spheres: namely oper-


ation, research and management, the ontlook favors a growing demand for competent engineers.

This very diversity of career opportunities serves to enhance thc favorable ontlook for young men interested iu the mineral engineering profession. This imposes a problem for the colleges iu designing curricula tliat w i n be best for thc new graduates aud still serve his professioual needs 10, 20, or 30 years after gradaatiou. Dr . Vanderwilt said: "Spokesmen f rom higher echelons iu industry make urgent appeals for broader education with a greater stress on the fundamentals of the physical ''sciences. The interviewers who do the hiring more commonly emphasize competence for special needs. Some advocate emphasis on theory to the exclusion of application. It is suggested that liberal arts pre-cngineering requirements are desirable. A five-year undergraduate course has been a common subject of discussion for many '-ears. Despite these differences, there is unanimous agreement on the need to keep engineering education standards high and to strive for continuing improvement.

"Engineering education is sensitive to change i u industrial needs and t e c h n o l o g i c a l development. Marked changes in curricula have occurred. A general trend has been for greater emphasis on fundamentals of physical sciences and mathematics. Training in routine skills has become relatively scarce. More non-technical courses, especially in the hmnan-istic areas have been added. Advance study is recommended for an increasing number who wish to specialize i n a particular subject or f ie ld ."

Cei'tainly a shortage i n the supply of new mineral engineering graduates is indicated, particularly i n 1962 and 1963. A f t e r 1963 the shortage w i l l con-tinue^ as long as engineering freshman enrollments remain low. Therefore i t becomes important to consider what can be done to encourage more young men to enter mineral engineering. This is pr imari ly the responsibility of industry, for in other fields, notably electrical, chemical and aviation, corporations have recognized this need by organizing programs on a national scale to attract bright students to their respective engineering fields.

The downward trend in freshman eurolhnent must be reversed i f the indicated shortage is to be overcome. The responsibility for this task must be shared by the educational institution, professional societies, aud industry. Colleges and engineering departments are dedicated to the cause of quality in engineering education, and they have neither the time nor resources to present the cause of the mineral industries to parents, liigh school counselors, and the students necessary to attract those young men of high school age "who possess thc necessary aptitudes and training.

Dr . Vanderwilt concluded that "the ultimate distribution of engineering manpower w i l l favor those industries which are most successful i n making knovra what their respective fields have to offer i n salaries, job advancement opportunities and satisfying life careers.

"The mineral industries, which indeed offer a wide variety of career opportunities, have a good story to tell i n competition for additional mineral engineering manpower resources. They must tell it more often and more emphatically in the future i f they are to meet the needs that lie ahead."

In comparing the differ ing positions taken bv M r . Brinckerhoff and Dr . Vanderwilt, it would appear that the f ina l solution of the problem of mineral engineering education must lie somewhere between these two positions.

M r . Brinckerhoff closed his address with the statement, "Student enrollment i n our engineering schools w i l l increase when those teaching mining engineering offer programs tadored to the needs of the modern world. This means a broad engineering course i u the ini t ial stage and specialization as the f ina l stage."

On the other hand, Dr . Vaudei-wilt said, "The ultimate distribution of engineering manpower wi l l favor those industries which are most successful in maldng Imown what their respective fields have to offer i n salaries, job advancement oppoi^tunities and satisfying l i fe careers."

There we have it—the fault of neither the educator nor the mineral industries, but perhaps it may have been their mutual failure to recognize the problem before it became acute. Mineral industries have not initiated a program to recruit promising students as have the electrical, chemical, and aviation industries. Perhaps the mining colleges fe l l into a trap, feeling that since industry was satisfied with their product, why worry about a lot of changes that no one wanted.

Concurrent with this complacency, mining entered the doldriuns, and i n some metals panic ensued. A cry went up for government controls, uot recognizing that down that road lay the same disaster that has overtaken the farmer—the solution is more appalling than the problem. Now to worsen thc situation, petroleum has added its platut—over-production and proration. We cannot dismiss these problems, nor can wc solve them with a single panacea. The future may not be blight, but is not bleak.

Min ing is a flourishing industry, although like a l l business i t has passed f rom the day of the individual small operator into the realm of the giant corporation. Yet the industry as a whoie is prospering, jobs are available, and increased consumption of metals point to the fact that as the tenor of ore decreases in value, great and abundant engineering talent w i l l be needed to extract it at a profit .

B u t what has happened to cause a decrease in student interest i n mineral education? Frankly I think the repetitious cry of hard-tunes has scared the prospective student, and you can't blame him. The reports emanating f rom the national mining and petroleum conventions speak of approaching disaster. These young men are smart beyond their years. W h y spend four, f ive or six years to gain an education in a f ie ld that holds little or no future?

Let's stop misleading the younger generation, stand on our feet and say: "Of eourse, we are having some difficulties at times, but the general trend of our business is upward. I f you graduate f rom a qualified school of mineral industries, there wi l l be a job waiting for you, a good, well-paying, satisfying job."

(EDITOR'S NOTE: This is the second in a. series of articles on the subject of "Mineral Engineering Education for the Future." The discussion will he continued next month ivith emphasis on ivhat Mines is doing about the problem.)

50 THE MiNES MAGAZINE • MAY, 1960

FROM THE EXECUTIVE MANAGER'S DESK

COL. WENDELL W. FERTIG

M a g a z i n e preparation is a peculiar business for here I am writ ing for the the May issue just as the A p r i l issue is being received from the printer. Under those circumstances there is no possibility of using any suggestions that -you might make to improve the May Magazine.

In A p r i l , we nsed a new cover (the gold color is not exactly the right shade yet), introduced new typefaces, restyled thc Table of Contents page, blackened

up the titles, and added additional material that should be of interest to the alumni. Let us know whether or not you like it.

Future plans for the Magazine show the June issue as the traditional Commencement number, a tribute to the greatest School of Mines. Ju ly wiU spotlight mineral developments and production i n the neighboring state of Wyoming. October w i l l be the Golden Anniversary number of The M I N E S Magazine which wi l l complete 50 years of publication that month.

Other issues are being planned to broaden the coverage of the magazine but they w i l l require additional money. We w i l l need your help i n obtaining the advertising that w i l l help us carry out these plans in a manner in which you wi l l be proud.

Office News Your association w i h move into its new offices

sometime i n May. The two old math rooms i n the northwest corner of the second fioor of Guggenheim are being rehabilitated. The Association has gone second class long enough, putting up with inadequate and unattractive quarters. Now at least we wi l l have a pleasant place to greet you when you come to call.

Members of the office staff are loyal and overworked. Certainly it is not the mediocre salaries that we pay (fringe benefits arc unknown) that keep them with us. There must be a loyalty that develops with the feeling that we are working for a fine gronp of altunni. W i t h your support, aud I mean the support of each of you, the office staff w i l l operate an association that is unsurpassed and w i l l tui-n ont a Magazine that you can claim with pride.

Financial Problems Annual dues—If we could collect all dues with, a

single mailing, two things would be accomplished:


(1) money would be saved, for each individual mailing costs at least 23 cents, which multiplied by foru-times, if we have to mail that often, is about one dollar or 20 per cent of the individual dues collected; (2) your personal mail would uot be cluttered up with frequent requests that dues be paid. A s soon as we receive your check, your card is tabbed, and no additional requests are sent. Of course being human, we do make mistakes, but I believe they are rather rare.

Advertising revenue—The May issue contains less advertising than did the Special Mining issue of 1959. Yet we have gone ahead with a special cover, added extra pages, and expect to turn out a Magazine of excellent appearance. Now i f each of you wi l l caU this to thc attention of the advertising manager of your own company, the trend w i l l be reversed and advertising revenue wi l l increase again.

Membership—The head of each degree granting department has joined iu our effort to obtain every 1960 graduate as a member before he leaves the campus. I f this campaign is successful, we will, have the name of each graduate i n our records and this is the key to keeping it there. According to our experience, every 1960 graduate wi l l move at least once during his first two years after graduation and some wi l l move as many as four times. I f the graduate "will write us, we w i l l keep his records up-to-date regardless of how many times he may move.

Turning to active membership among the graduates of older classes, we find that the percentage of active members varies widely. Por some reason the Denver area has the poorest record, while a few sections, both local and foreign, have 100 per cent of all g];aduates i n their area as active members of the Association.

Annual Banquet This w i l l be held at the University Clnb at 6 :30

p.m. Thursday, May 26th. A l l members of the class of 1960 w i l l be our guests. We should have enough members present that night to make our guests proud to wear the title of M I N E S M E N .

(See A lumni News for the menu served at the Fi rs t Annual Banquet of the C S M Alnmni Association at the Windsor Hotel, June 7, 1895.)

To The Mines Graduate Won't you come out and see , what we arc doing?

Our invitation is extended to al l graduates. Distance is no bar, come from Denver, Arvada, Englewood, or Timbuktu, hut come. Y o u wiU find that we are trying to do a job for you. Whether or not it succeeds may weU be your decision, for the Association is only as strong as the support given by the individual alumnus.

ALUMNI BUSINESS Executive Committee Postpones April Meeting

Executive Committee meeting was held at Stearns-Roger Building, 660 Bannock St., Denver, on March 17. However, the Apr i l meeting was postponed until early May in order to pass on plans for the annual banquet. Thus the minutes of the March meeting have not been approved and consequently wi l l not be published until they are approved.

I'he Publication Committee, as announced hy Robert Bolmer, chairman, has agreed to use the general theme of "Secondary Recovery" for the 25th, Silver Anniversary, of the Special Petroleum issue. It wi l l be published in November i960. Additional announcements wi l l be made later.

_ "The M I N E S Magazine is definitely interested in articles covering all phases of secondary recovery," M r . Bolmer said, "and we invite you to submit them to the editorial staff. It w i l l take a great deal of work to make this issue a success and I hope that we may have the help of everyone of you who are in the petroleum industry."

Iranian Graduate Student Inquires About Alumni Assn.

Mahamad Assadi, who received a degree in mining engineering from the University of Iran and who is now doing graduate work in petroleum geology at the Colorado School of Mines, was a recent visitor to the Alumni Office.

M r . Assadi was interested in learning ahout the Alumni Association— what it is and what it does. After a brief explanation of our aims and services for Mines alumni, he completed an application for junior membership.

Although M r . Assadi already has a position in Iran when he completes his studies, he said he was impressed by the Placement Service, the Mines Magazine, and the Directory. He hopes to complete his studies and get his M.Sc. in 1961 after which he wi l l return to his homeland, where his address is Shemiran Rd., Teheran, Iran.

Public Relations Committee Members Are Appointed

The Public Relations Committee vpill consist of the following members;

Warren C. Prosser, x-'07, chairman; 41+ Cooper Bldg., A L 5-9827.

CSM and Alumni Assn. Sponsor Display Booth

I ,2

Colorado School of Mines and the Alumni Association were co-sponsors of a small display booth in the Exhibitors' section at the National Western Mining and Energy Conference. The booth was manned by a member of the Alumni office staff and student volunteers from the C S M Student Chapter, A I M E . Many visiting alumni, as well as friends of Mines stopped by to chat and look at the display of pictures and copies of T H E M I N E S M A G A Z I N E . This provided an opportunity to point out the good points of our Magazine and to solicit subscriptions.

The booth and display proved so successful that plans are underway to enlarge it for the 1961 National Western Mining and Energy Conference and to consider its use at other mining and petroleum conventions. Local sections are encouraged to write for information and assistance in using this display at mineral industry meetings held in their own respective cities.

Publications Committee Meets The Publications Committee met in the

Alumni Office on March 29 to discuss plans for future issues. Kirk Forcade agreed to prepare a rough p!an of action for use in promoting the annual petroleum issue of T H E MINES M A G A Z I N E , which will be published in November I960 with the theme of "Secondary Recovery." This will be the 25th and silver anniversary of the petroleum issue.

Present at the meeting were Kobert L, Bolmer, '44, chairman; Maynard F. Ayler, '45; Kivk C. Forcade, '36, and Francis E . Smiley, '40.

Elmer J. Garbella, '30, has been named a member of the Publications Committee.

George Roll Assembles Alumni Assn. Records _ Although M r . George Roll re

signed as executive manager at the end, of January 1960, he has continued to devote a portion of his time to segregating and filing in appropriate folders important records of the Alumni Association. Over the years these records of meetings, financial reports, and general business activities have been accumulated in various packets, whose contents were only vaguely known. Now by collecting, sorting and refilling, these records are readily available for use and wi l l be preserved for historical purposes.

From the monetary point of view, this effort would have cost us several hundred dollars. Only some one with M r . Roll's intimate knowledge of the association and its operation could have identified these documents read-ily.

M r . Roll , we of the office staff thank you for your help in arranging these records in an orderly and accessible fashion.

Committee Members Appointed Ben Essig, '15, has accepted the

chairmanship of the Endowment Committee and has named C. D , Deringer, '24, as a member of the committee.

Ken Nickerson, '48, chairman of the Membership Committee, reports that Dr . Leshe LeRoy, '33, Niles Grosvenor, '50, Fran Smiley, '40, and George Welch, '59, are members of the committee.

strock, '22, Succeeded By Parker, '49, at Butte

GEORGE PARKER

Hale M . Strock, '22, assistant general superintendent of Butte mines, retired at the end of Apr i l and was succeeded by George Parker, '49, former superintendent of the Berkeley Pit. The announcement was made by E . I. Renouard, vice president of Anaconda Co.'s western operations.

A native of M t . Morris, III, M r . Strock enrolled in the Colorado School of Mines in 1917. He had a period of Army service in 1918 but after the end of Wor ld W a r I resumed his studies, receiving an E . M . degree from the Colorado School of Mines in 1922. A noted athlete in college, Hale won the Colorado amateur and intercollegiate welterweight titles. He served a 5'ear as boxing coach at Mines.

After graduation from Mines M r . Strock came to Butte and started as a miner at the Pennsylvania mine. The next j'ear he was a shift boss and then a sampler. He left Butte in 1924 to work at Cripple Creek, Colo., hut returned to the Anaconda Co. in 1928 as a sampler at the Tramway. He became assistant foreman of the Leonard fire f i l l in 1929 and foreman of that unit in 1934. In 1937 he was made chief assistant foreman of the Leonard mine and superintendent of the Leonard in 1939, the position he held until promotion in 1947 to assistant general superintendent.

M r . Parker, a 1949 mining engineering graduate from the Colorado School of Mines, has been superintendent of the Berkeley Pit since 1956. His college studies were interrupted by more than five years of military service during and after Wor ld War II.

Entering the Army Corps of Engineers in 1942 as a second lieutenant, he was discharged in 1947 as a lieutenant colonel. He had three years of service in the Pacific and commanded the Engineer Squadron of

the First Cavalry Division. He was decorated for bravery in the Philippines campaign.

Before coming to Butte, M r . Parker worked for Chile Exploration Co., an Anaconda subsidiary in South America. He started as a junior engineer in 1949, became shift foreman in 1951, assistant foreman in 1952, and general mine foreman in 1955.

R. H. Volk, '26, on Committee Studying Oil Industry Problems

Visitors to the Alumni Office

L U I S H . A G U I R R E , '51, together with his wife paid us a call during his state-side vacation. Luis is mining engineer, Neptune Gold Mining Co., Bonanza, Nicaragua. W e were happy to see Luis for our records still showed him at his former address in Antofagasta, Chile.

B E N J A M I N A R K I N , '27, stopped here long enough to pick up a list of addresses of M I N E S M E N that he may be able to see on his extended trip through Mexico and later up the West Coast as far as San Francisco. The Arkins should be back in Denver in about two months.

J O H N A . B O W S H E R , '34, 900 W . Quartz St., Butte, Mont., is now doing consulting work, mostly in the Montana area. John was in Denver for the National Western Mining Convention.

J A M E S H . B R I G H T , '52, who is still with Carbide Nuclear and living at 1340 Oxford Ave., Sparks, Nev., was in Denver due to sickness in the family. M r . and Mrs . Bright were able to stay long enough for us to mine out a couple of asbestos deposits before they had to leave.

H A R R Y A . E L L S , '54, called to talk over alumni problems so that he could report back to the Tulsa Section. Harry is studying law at the University of Oklahoma. He finds that his engineering education comes in handy for he is teaching some courses in the Engineering School of the University while attending law school. I expect Harry to head back for the Denver area as soon as he graduates from law school.

P H I L O D . G R O M M O N , '07, was in Golden for the afternoon, W e have had a pleasant correspondence the last few weeks, so he called to talk about some old friends. Philo is living in Berthoud, Colo.

A R T H U R J , J E R S I N , '49, director of the Colorado O i l and Gas Conservation Committee, came to see us in order to obtain some biographical material on one of our old-timers. No use mentioning any names for I do not know what Arthur wi l l use the information for, and I might be giving away secrets.

S I D N E Y A . J O H N S T O N , '55, is visiting his parents, M r . and Mrs, Dave Johnston here in Golden.

A L B E R T M . K E E N A N , '35, came out to the office so that we could furnish him addressed envelopes for the members of the class of 1935. A l Keenan is chairman of the committee in charge of the Silver Anniversary celebration of that class. Hope they have a fine representation, for it is a long time until their next formal reunion in 1985.

G E O R G E J . K I R N , '57, is a geologist with Pan American, and whose mailing address is Box 1437, Bismarck, N . Dak, George was just in town for a couple of days but came out to the Alumni office and to see Dean Burger.

M I C H E L J . L O E B , '48, came back to Golden for the first time in more than 11 years. It was good to talk about Brazil and their prospects with one who knows the picture intimately, Mike was much interested in plans of the Alumni Assn. He carried our best wishes back to the Moraes family and others of our alumni in Sao Paulo.

R I C H A R D K . O ' N E I L , '57, production engineer. Continental O i l Co., Riverton, Wj'o., told us the problems of living in the wilds of Wyoming, I could sympathize for I spent parts of two winters in Gas Hills , It's a rough country—climatically at least.

T H O M A S E . P H I P P S , '49, combined the job of setting up the exhibit, prepared for his company, Western Machinery Co., for Engineers' Day by coming to see us. It was a good exhibit and proved interesting to the students.

LETTERS TO THE EDITOR G E N E K A E F E R , '53, writes, "It is the

job of the alumni that are in the association to sell the wayward ones who have not yet joined. They must be made to realize that only thru a strong alumni association can our alma mater progress. It is also by a strong alumni magazine such as onr MINES M A G A Z I N E that we can progress. This magazine is extremely important to us, and we must stand behind it and help it progress,

"In answer to your questions on Page 27 of the April issue, I have this to add: I believe, basically, the magazine is fairly well rounded. I believe it should be directed more and more to the various industries that it is serving so that there will be an increase in the desire of people in industry to subscribe to this magazine. This will make people more familiar with our school and will also be an incentive to manufacturers to use the magazine as an advertising medium,

"Here is wishing you all the success in the world. Call on me if I can be of assistance to you,"

(Editor's Note: Gene is product manager, Hydromatic Brakes & HYDRO-TARDERS, Parkersburg Rig and Reel Co., P.O. Box 573 Coffeyville, Kans. Thawks for those kind tvords. We IDUI do our hest here, and njith the support ivhic/i you expressed, there is no doubt of our success.)

R O B E R T S. S T O C K T O N , '95, writes: "The class of '95 was responsible for the organization of the Alumni Association, and our committee under Joe Kennedy designed the alumni pin still in use . . . I was secretary for the first 8 years and arranged the annual meetings at thc Windsor and later at the Albany Hotel. When I left Mines, I was president for two years—moved to Canada and gradually lost contact except through T H E MINES M A G A Z I N E .

"The mention of T i n Cup reminds me that as a boy I read a story in the St. Nicolas Magazine called the Tink Boarding House.' In 1888 or 1889, I took a trip with the Nichols family and Johnny Adams from Silvercliff to Aspen with a four-mule freight team. Johnny went to get work hauling ore, and the Nichols family and household goods were the load, Mr, Nichols was an assayer and had opened an assay office in Tourtelletts Park near Aspen. We drove up the A r kansas to Buena Vista and then up Chalk Creek and over two ranges and passed through the village of T i n Cup, and I thought it so remarkable to have seen the location of the story."

(Editors Note: To those around Denver, you see that Pete Smythe's Tin Cup did actually exist until he insisted on moving it to "East Tin Cup" hy "stimulated remote control.")

R O N A L D P. F I T Z G E R A L D , '10, writes, "When a man graduates with a degree from C S M he is thereafter a MINES man for the rest of his life (whether he likes it or not, or whether he shows signs of cooperating with the Alumni Association or not). He may in fact, be quite an individualist, and out mainly to accumulate money and reputation for himself alone, without remembering the Alma Mater from whom he got his original training."

DR. W I L L V. N O R M S , '21, writes: "At the present moment I am in fair health, in fact considerably better than a few years ago. However, I have decided to retire from active teaching at the end of the present academic year, having quit all administrative duties a year ago. I was assistant to the President; chairman of the Division of Science, and consulting engineer on campus planning (Portland State College) for many years. We are not sure what we will do after September, maybe move to southern California where the weather is better.

"I hope to visit Golden sometime in the near future."

that after working for the Bunker Hiil Co, at its Bunker Hill Mine, Kellogg, Ida., for the last six months he has accepted a position with Sunshine Mining Co. of Kellogg as a mining engineer. He writes: "The Sunshine Mine, in Big Creek Canyon east of Kellogg, is the largest single lode producer of silver in the worid with an average annual production in excess of 6 million ounces. The ore, which is mainly tetrahedrite assaying about 30 ounces per ton, is hoisted 4000 feet through the Jewell shaft at the rate of 950 tons per day."

« * * C H A R L E S E . S T O T T , '25, writes:

"With regard to my doing a short article for T H E MINES M A G A Z I N E , I have been giving it some thought and will do so providing you are not in a hurry. The 'Tsumeb Story' by M . D. Banghard appeared in publications of The Mining and Metallurgical Society of America some years ago, which as I recall, briefed the historic background and events leading up to the acquisition of the mine by the corporation and bringing the property into production; also a description of mining and milling methods. There have been many developments since that date, both in the successful exploration of the ore body to a depth of 4,350 feet and improvements in the metallurgy and enlargement of plant with increased production of our six products, copper, lead, zinc, silver, cadmium and germanium.

"For the next two years I will be pretty well tied up in pushing the construction of copper smelter, germanium recovery plant at Tsumeb, and the exploration development and equipping of our nearby copper-lead mine at a place called Kom-bat, some 40 miles distant. However, I shall try my best to get out a brief article on general lines for T H E MINES M A G A Z I N E .

"We find the climate about the same as Rhodesia but, nevertheless, somewhat enervating. Fortunately malaria has been eradicated in our mining area and we are not plagued with any other tropical diseases. Recreational facilities are unlimited here if you like the outdoors. The main thing is to iind time to enjoy them. Big game hunting is possible but it takes time. However, I keep up my rifle practice on the local rifle range, and in spite of my white hair and 'new eyes,' have managed to cart away several prizes."

(Editor's Note: Tsumeb, South West Africa, property has a fascinating history and a prosperous future seems assured. }V.W.F.)

Leo A. Scherrer

Leo A . Scherrer — a raan who throughout his life extended a helping hand to others less fortunate than himself—died Feb. 29 at his home in Seattle, Wash. Services were held at St. Alphonsus Church on March 2 with the remains being placed in Washelli Mausoleum.

During 24 years of happy married life, M r . and Mrs. Scherrer adopted three children, six other children lived in their home from nine to 20 years, and a number of other young people were put through college. During the war, the Scherrers had over 4,000 boys in their home overnight and served more than 20,000 meals to servicemen. M r , Scherrer's generosity knew no limitations and he left thousands of friends of all colors and creeds in all walks of life.

Born in East St. Louis, Mo . , on November 12, 1901, he moved to Pueblo, Colo., as a child and was educated in the Pueblo public schools. Wi th thc thought of eventually selling mining engineering equipment, M r . Scherrer enrolled at the Colorado School of Mines and graduated in 1924 with an E . M . degree. He was about to accept a position with Youngstown Steel & Tube Co. when his grandfather's health failed, so instead he went to Los Angeles to look after his grandfather's affairs—as representative of several toy manufacturers. He liked the work so well that it became his life's vocation.

For the next 10 j'ears he traveled 11 western states. In 1934 he moved to Seattle and on Nov, 7, 1935 he married Miss Bernice Wise. His company, the Leo A . Scherrer Co., represents some of the top toy manufacturers in the United States.

Organizations to which he belonged were the American Institute of M i n ing and Metallurgical Engineers, Far Western Toy Club, Colorado School of Mines Alurani Association, Eta Oraega Delta, Seattle Tennis Club, and Washington Athletic Club.

Survivors include his wife, Mrs . Bernice Wise Scherrer, and three adopted children: Leo A . , Jr., Edwin C , and Nancy Ann.

Daniel Harrington

Nationally recognized for promotion of mine safety, M r , Harrington was chief of the Health and Safety Division, U.S. Bureau of Mines, Washington, D . C , when he retired in Apri l 1948. During his career he wrote more than 250 articles about probiems involving health, ventilation, dust and safety in the coal and metal mines of this country. He was a 1948 recipient of the Colorado School of Mines' D i s t i ngu i shed Achievement Award for his contributions to mining safety.

Born Apr i l 26, 1878 in Denver, M r . Harrington graduated in 1896 from West High School and received his E . M , degree from Mines four years later.

His first professional job was that of mine surveyor at Utah Fuel Co.'s Sunnyside Mine. During his seven years at Sunnyside, Utah, he became successively construction superintendent and chief engineer.

In 1907 he was construction engineer at the Eureka, Utah metal mine operations of U.S. Mining Co. He

engaged in consulting work from 1908 through 1909, and in 1910 he became general superintendent of the coal operations of the Big Horn Col-leries at Crosby, Wj 'o .

In 1914 he was appointed mining and supervising engineer in charge of investigation work in mining west of the Mississippi River for the U.S. Bureau of Mines, a position he held until 1924 when he returned to private consulting work in Salt Lake City for two years,

M r , Harrington was recalled in 1926 to the U.S. Bureau of Mines as chief engineer of the Safety Division, and in 1933 he was named chief of Health and Safety Division,

Survivors include three daughters, Mrs . Mary Lord and Miss Florence Harrington, both of Arlington, and Mrs. Cecile Foster, Chevy Chase, M d . ; a brother, Thomas S. Harrington, Denver; two sisters.

Lima Section

Newly elected officers for 1960 are:

Richard N. Spencer, '34, president Martin Obradovic, '53, vice-president Norman R. Zehr, '52, secretary-treas

urer

W e are especially glad to have Martin Obradovic as one of the officers as he represents the "Sierra Group" of our membership, which is a large part of our organization.

On Apri l 1, the first Friday of the month, we had our first regular luncheon meeting of the 1960 season. It was held, as usual, at the Hotel Crillon. Present were Robert Couch, '36; Martin Obradovic, '53; Richard Spencer, '34, and Norm Zehr, '52. W e were again able to take advantage of the wonderful "senoritas" which are available at the Hotel, To clarify such a remark, I should add that a "senorita" can also be a small shell fish, much like a scallop, which when properly prepared by broiling in the shell with Parmesan cheese, is a real delicacy. (We did feel that an explanation was in order,)

Business discussed Included the possible enrollment of two Peruvian engineers in the Graduate School and the possible enrollment of a third Peruvian now in the U.S, We also talked about our plan to have a cocktail party before the annual A I M E dinner-dance, which is usually held in June. It was agreed that a large number of our members would be in Lima for that affair.

The next luncheon meeting wi l l be held on the 6th of May at 12:30 in the Hotel Crillon, We hope that some visiting Miners wi l l be able to attend, and aslc that they contact Norm Zehr at IngersoU-Rand Co, in Lima.

CAMPUS HEADLINES

CSM Department off IVIining, I960

By MAYNARD F. AYLER, '45

During a recent conversation, the point was made that many graduates of any school do not return after their graduation. For them school stands still—it is always the same as they knew it. The faculty, courses, and facilities are thought of as unchanging except possibly an occasional chance comment such as, "1 wonder what happened to old Dr . so and so?"

Throughout the years many things have changed at Mines, and the M i n ing Department is no exception. The faculty has changed, continued alterations have changed the interior of the old Mining Building. But first you should meet the faculty, starting with those who are senior -in length of service.

L U T E J . P A R K I N S O N , Mines '23, has been professor and head of the department since September 1952. Upon graduation. Professor Parkinson went to Africa and spent the next 20 years there. During this period he was head of the Department of Planning and Study for Dagga-fontein Mines Limited, and later served as general manager for three different companies at various stages of his career: Companhia de Dia-mantes' de Angola, the Consolidated Diamond Mines of South West A f rica, and the parent DeBeers Co.

The following eight years were spent in mine examination work in Brazil and as a mining consultant in Chile.


At "Mines," in addition to administrative duties, he regularly teaches a course entitled Mine Examination and V a l u a t i o n . During summer school, or when necessary, he teaches any of the several other courses normally taught by the department staff. For variety he heads up a group of visiting lecturers at Guanajuato University in Mexico and has lectured at other schools of mines in America, Europe, and South Africa,

N I L E S E. G R O S V E N O R also joined the department faculty in September of 1952. During Wor ld War II, he spent five years with the U . S. A i r Force. He was graduated from "Mines" with an E . M . Degree in 1950 and received his M . S . Degree from the same department in 1952. He taught in the department until 1957 when he took a year's leave to attend Columbia University. As soon as his thesis is completed, he wi l l receive a Ph.D. in the field of rock mechanics, from Columbia. In addition to this formal training, he is a Certified Coal Mine Foreman in Colorado.

During summer periods, he has been in charge of ice tunnel excavation for the U . S. Army Corps of Engineers in Greenland and has worked for Kermac Nuclear Fuels, Kerr-McGee O i l Co., and San Miguel Power Co.

Courses taught by Professor Grosvenor include Mining Methods,

Rock Mechanics, Coal Analysis, and Mine Surveying,

C H A R L E S O. F R U S H joined the staff as associate professor in 1956. He was graduated as a M i n ing Engineer from Iowa State College in 1941. After graduation, he joined the engineering staff of the Chile Exploration Co. at Chuquicamata Chile. In 1944, he joined the U . S. Smelting, Refining, and M i n ing Exploration Co. at Eureka, Nev. A year later he returned to Iowa to assist in the organization, development, and operation of a new coal mine.

In 1945 he joined the Mining Department staff at Iowa State University, did graduate work, and was on the staff of the Iowa Engineering Experiment Station doing research on the utilization of coal mine wastes.

Courses taught by Professor Frush include Mine Surveying, Mining Law, Surface Mining, Mine Plant, Tunnehng, Mineral Economics, Coal Preparation, and Mine Safety.

In September 1957, J O H N M O S S J O N E S joined the department staff as an instructor. He was graduated in 1955 with a First Class Honors Degree in Mining from the University of Wales. He spent five j'ears with the National Coal Board in the United Kingdom during which time he received a Mine Managers Cer-

63

tificate. In 1957 he received a Master's Degree in Mineral iLconomics from Pennsylvania State University. For the last two years he has been ventilation consultant at the Climax mine of American Metal Climax Co. He is currently worlcing toward a Ph.D. in mining.

Courses taught by M r . Jones include Introduction to Mining, Mine Industrial Engineering, S ta t i s t i ca l Analysis, Penetration and Fragmentation, Mine Administration, Mine Ventilation and A i r Conditioning, and Advanced A i r Conditioning.

In February of 1958, M A Y N A R D F. A Y L E R , a 1945 graduate of the Mining Depar tment of "Mines," joined the department staff as an instructor. During the intervening 12 years he worked for 18 months as an engineering geologist for the U . S. Bureau of Reclamation; served for one year with the U . S. Army; worked as a petroleum geologist in several parts of the U . S. during a five year stay with the California Co.; and spent the remaining years as a mining consultant specializing in mine examination, valuation, and exploration. He currently is working toward an M . S . Degree in Mining.

Courses taught include An Introduction to Mining, Mine Exploration, Mine Development, a Mining Problem (where each student prepares a complete report on a mining property), and Mining Laboratory.

D R . J O H N S. R I N E H A R T is the most recent addition to the department staff, having joined the faculty as a professor in September 1958. In 1934 he received a B.S. Degree in Education and the following year received an A . B . Degree in Physics from the Northeast Missouri State I'eachers College. In 1937 he received an M . S . Degree in Physics from the California Institute of Technology and a Ph.D. Degree in Physics from the State University of Iowa in 1940. Dr . Rinehart has taught at Fort Hays Kansas State College, State University of Iowa, Wayne University, New Mexico School of Mines, University of California, Harvard University, and has lectured at Cambridge University in England.

He has worked on several government research projects, including one concerned with problems of fracture and deformation of materials when subjected to impact loads and exploding charges. In 1955 he became assistant director of the Smithsonian Astrophysical Observatory and research associate at Harvard University, the post he left to join our department staff.

Dr . Rinehart's function in the department has been to direct and extend graduate studies. A plan was adopted to establish a center for graduate study and research in the general areas of fragmentation, impact, and explosion dynamics as applied to the mineral industry. In addition to his research and graduate school duties. Dr . Rinehart teaches Impulsive Loading Phenomena I and 11.

It should be noted that the entire staff has joined the Mining Department since 1952. They have brought wide experience in practice and in education to the problem of changing and modernizing the curriculum as a whole. In some cases, course names remain the same, but content has changed so that it remains current or even ahead of the rapid developments of the day. T o do this it is necessary to drop or eliminate some courses to make room for others that more important. appear

In the past ten years, Mine Rescue and First Aid , Fire Assaying, and Accounting have been dropped from the required list. Mining Methods, Mine Examination and Valuation, Mine Ventilation and Mine Surveying have all been reduced in scope. It is now suggested that Mining Methods be included with Mine Development to make room for a course in Quality Control.

Courses in Mine Industrial Engineering, Rock Mechanics, Statistical Analysis, and Soil Mechanics (an elective at present) have been added. In all cases, more stress is placed on the analytical approach, with due attention to h i s to r i ca l background. "Why" is now more important than "how." More stress is placed on current articles in technical publications and less on texts that grow obsolete in the light of present rapid progress.

The facilities within the department are continually being improved and are quite modern. This leads to better teaching and enables the student to enter industry "abreast of the times" rather than being burdened with knowledge that is already passe. Thus he has the knowledge necessary to be of immediate use to his employer.

The Mining Department wishes to extend an invitation to each of you to come and visit the department. If you cannot gain first hand information by a visit, write and ask for any information that you may need.

(Editor's Note: Additional information on curriculum and pictures of facilities will be given from time to time. See ihe ai'ticle, "Experimental Mine" in this issue.)

26th Annual Engineers' Day, April 1-2

Engineering school graduates are in a more favorable position today than ever before to enter the management field and achieve outstanding success, declared Cris Dobbins, keynote speaker at the Colorado School of Mines 26th Annual Engineers' Day program, Apr i l 1-2. Dobbins, president of Denver-based Ideal Cement Co., said his company employs 14 Mines graduates and that eight of them are in management positions.

Dobbins stated the major obstacle in the engineers' path to management was the barrier of seeing everything in the framework of engineering. "But," he added, "the engineer is superbly equipped to apply the logic analysis to business data. He has all the tools—-the problem is that he too often tends to exclude the illogical and intangible from his thinking. When his eyes are open to the fact that business embraces a whole range of problems that cannot he solved by the technical approach, he has an edge over his non-technical colleagues that they find hard to equal,

"Engineering is an honorable profession and an end in itself," Dobbins said, "and a good engineer can stand on his own feet in any company without regard to management ability or management responsibility . , . The rapid introduction of electronics and automation in industry should give engineers an advantage in getting into the management field . . . Our own experience is graphic proof of the fact that there is a place in management for the engineer."

The two-day event also included presentation of honors and awards, exhibits, technical sessions and discussions, engineering contests, a sports car exhibit, a raft regatta in Clear Creek, tours of the campus and of the School's Experimental Mine at Idaho Springs, and a dance at the Brown Palace West Hotel. Euclid P. Worden, a mining engineering senior, was chairman of CSM's 26th Engineers' Day, which has evolved over a 34-ycar period from a simple tour of the campus by a few engineers to an annual spectacle with hundreds of participants.

Following M r , Dobbins' address, the following awards were presented :

Full four-year scholarships to Mines to High School Seniors Wayne E . Stief-vater of Denver, Robert O. Schueike, Jr., of Lakewood, and Douglas F. Farris of Goiden.

A silver medal by the Colorado Engineering Society to John J. Selters, as Outstanding Senior Class member.

A gift certificate by the School's senior class to Marvin Kay, as Outstanding Junior Class member.

A certificate by Sigma Gamma Epsilon to Thomas C. Tisone, as Outstanding Sophomore Class member.

A certificate by Tau Beta Pi to Donald D, Snyder, as Outstanding Freshman Ciass member.

Fifty dollars and a certificate from the Denver Geophysical Society to Kenneth L. Earner, for being top geophysics student.

A certificate and a magazine award by the American Society of Mechanical Engineers to John R. Smith, for his excellence in the field of machine design.

Honored title of "Mr. Engineer" b3' vote of assembled Mines students to James R- Heavener, geophysical engineering senior.

Prizes for the best student exhibits in Steinhauer Fieidhouse were awarded on the basis of originahty, completeness and neatness. Exhibits were prepared by the students themselves to illustrate the particular option or field of endeavor. A l l departments were represented, and judges' decision was close. Judges were M r . Dobbins, C S M President John W Vanderwilt, Dean Wil l iam Burger, Prof. Ivan Hebel, and Col. Wendell W . Fertig of the Alumni Assn,

FIRST PRIZE. Mining Dept. Classroom, laboratory and field (practice mine) problems were illustrated. Realism was provided by the lingering odor of burning fuse. Exhibit was difficult to photograph since it was built in a simulated mine tunnel.

SECOND PRIZE. Metallurgy Dept. Exhibit traced the metallurgical treatment from raw zinc ore through the flotation process or leaching and then electrolitic recovery of the metallic zinc. Metallic zinc alloyed with a small percentage of aluminum to improve casting of small slugs which were given as souvenirs.

T H I R D PRIZE. Tie between Petroieum Refining and Civil Engineering exhibits.

Petroleum Refining exhibit illustrated the treatment of oil shaie on a laboratory scale and recovery of final end products of gasoline, diesel oil, and heavy tars by

15 ROTC Students Tour Waterways Experiment Station

Fifteen Advanced Course R O T C students flew to Vicksburg, Miss., for a tour of the Army Corps of Engineers Waterways Experiment Station during spring vacation. The students, members of the Mines post of the Society of American Military Engineers, left Lowry A i r Force Base Apri l 13 and flew to Jackson, Miss., then went by bus to Vicksburg. They returned to Mines on the afternoon of Apri l 16.

A t the Waterways station the cadets saw elaborate operating models of the New York Harbor, Niagara Falls and parts of the Mississippi-Missouri-Ohio River system. This latter model covers over 200 acres and reproduces 41 per cent of the land area of the United States. These models are used to study the effects of channel improvements and control structures on normal river flow.

In addition to hydraulic models, the cadets also saw testing laboratories for concrete, flexible pavements, soils, and other materials affecting Corps of Engineers structures or Army mobility. The cadets were surprised to discover that the Corps of Engineers is the world's largest single user of concrete.

One afternoon of the two-day visit was spent on the Civi l War battlefield at Vicksburg National Military Park, Here the cadets reviewed their military history while going over the trenches and rifle pits of one of the key battles of the war between the States.

The trip and accommodations, with the exception of meals, were paid for bv the Omaha District, Corps of Engineers,

Dr. Dodge Addresses Earth Sciences Fraternity

Purification of saline and brackish water was the topic discussed by Dr . Barnett F . Dodge at a recent meeting of the Mines chapter of Sigma X i , national earth sciences fraternity. Dr, Dodge is chairman of the chemistry department at Yale University and is national Sigma X i lecturer.

"Oceans are an inexhaust ible source of water," Dr . Dodge stated, "but the salt must be removed for raost uses. Even then the purified water wil l be unavailable to locations removed more than a few hundred miles from the sea coast."

He maintained that the total rainfall on earth is adequate for all foreseeable needs, but that distribution is very unequal and serious water shortages exist in many areas.

"All told, the pre-election campaigning was not performed by boys who take life easy. It was one which showed the terrific competitive spirit which is always present at Mines.

"And so the election went through the day, with the Seniors of '60 yelling at everyone that passed by the administration building; this was all in good faith, it is just that they didn't realize that janitors couldn't vote. But as a result of the labors of many individuals, the election turned out to be the 'best' Mines has ever had. And now the most important part of this informative article, the results.

"When the votes were finally compiled, it was found that Bruce Henry was next year's Student Body President. Bruce hails from Dallas, Texas, and is presently a Junior in the Metallurgj' option. He is in just about every organization that the campus affords."

And that started the excitement on thc campus.

"The supporters of Don Henderson, who was barely eliminated in the primaries, decided that he was still the best man for the job. And so on the day before the election, loudspeakers boomed, posters were put up, and the sidewalks were gaily painted. This began as a surprise to everybody, even Don, but it was taken in stride as Bruce Henry and Kim deRubertis increased their campaigns.

Ohio Oil Confirms Reserves. Acquires Aurora Gasoline

Outstanding developments in Ohio O i l Co's. 1959 activities were confirmation of a large reserve of oil and gas in Libya and acquisition of the stock of Aurora Gasoline Co. (which brought refining and marketing volumes into balance with crude oil production).

The greatest interest in the company's Libyan operations in 1959 was in the Dahra area of Concession 32 following a discovery there the previous year. Further drilling has proved a field of apparently substantial proportions. Eight Dahra wells were completed during the year; four of these were oil wells, three contain gas, and one was dry. T w o productive zones of wide areal extent are present in the Dahra held. Tests of three wells in the upper zone have indicated productive capacities ranging from 1200 to 8000 barrels per day. In the deeper zone, three wells have shown potentials of 400 to 1000 barrels per day.

Since the first of the j'ear, promising discoveries have been made on two other widely separated concessions in Libya in which, as in Concession 32, Ohio O i l holds one-third interest.

Continuous Vacuum Filter

The Straight Line Filter is a new horizontal, continuous vacuum filter which uses an entirely new type of vacuum seal with no movable valves and a corrosion resistant, sectionalized dra inage belt which permits close separation of filtrates.

It features extremely high capacity, low operating and maintenance costs, and takes less headroom and floor space than filters of equal capacity. The entire filtration cycle from feed to filter cake discharge is visible at all times assuring maximum operating efficiency.

Among the suggested uses for the new filter are: in chemical processing, sewage treatment, concentration of ores, filtering slurries, food processing, and in the pulp and paper industry. Maintenance costs are reduced because all parts are visible and accessible and no complicated valves and special assemblies are needed, Down time is reduced because the filter media can be removed and replaced in 30 minutes. No filter or slurry agitators are used.

The filter cake is formed by a combination of vacuum and gravity drainage and is discharged by gravity. Counter current washing or leaching can be used.

The company maintains testing facilities to test the efficiency of its filter on specific materials. Write to Straight Line Filters, Inc., Box 291, Wilmington 99, Del., for complete details about the new filter.

Manhole Cover for Mills A quick-opening manhole cover has

been designed by Allis-Chalmers engineers which permits dumping a grinding-mill load for speedy and efficient maintenance servicing.

Converting a grinding mill's regular cover to the quick-opening manhole cover is simple. First, the mill is stopped with the regular cover in top position by means


of the manhole positioning control selector switch. Upon removal of the regular cover and liner, the quick-opening manhole cover is attached to a hinge on the mill shell with a pin; the release latch is locked and secured, and the mill brought up to operating speed.

The mill is then stopped with the manhole in the bottom position. A chain or cable lanyard at least SO ft. in length is attached to the release latch, the latch locking bolt removed, and the latch pulled to release the cover and discharge the grinding media.

After maintenance servicing, the quick-opening manhole cover is removed and the regular cover replaced and secured with manhole crabs.

New Roof Bolt Mat

Development and satisfactory test of a mine roof bolt mat for use in mining and construction industries has been announced by Commercial Shearing and Stamping Co., Youngstown, Ohio.

Application of the new roof bolt mat graphically illustrates flexibility and firm support. Examples of overlapping can be seen at extreme left and in the foreground.

Used in conjunction with roof bolts, the new mat is employed specifically for prevention of rock sp ailing conditions. Light, easy to handle and install, the mat was designed to make mining and excavating safer and to reduce the number of roof bolts formerly required and provide support between roof bolts.

A key strength and cost reduction feature results from overlapping the mat either to continue a run or to bring a support line out from the center of another mat. This not only demonstrates the flexibility of use, but reduces the number of roof bolts required.

Thirteen inches wide and 108 inches long, the roof bolt mat has corrugated edges to provide proper rigidity for ease of installation and substantial support. At the same time, the mat is flexible enough to conform to the roughest contours of the mine or excavating.

The products are divided into four groups: glycerol esters, other poly-hydric alcohol esters, polyglycol esters, and poiyoxyethylene alkyl aryl ethers. The new bulletin suggests the considerable variety of chemicals that are available within each of the groups.

Hodag Nonionics find wide application in manufacturing and food processing, and in the pulp and paper, pharmaceutical, cosmetic, paint, adhesive, and agricultural chemical industries. Hodag's technical services laboratory is prepared to assist users in the application of nonionics, and the company is equipped to tailor-make products for specific uses. Copies of the new bulletin are available from Hodag Chemical Corp.

R E F R A C T O R Y C L A Y . The Refractories Division of Gladding, McBean & Co. has published a 4-page brochure entitled "The lone Story" which tells about its unique technique for processing refractory clay at lone, Calif.

The story of the new process is told by use of four-color photographs and minutely detailed captions. The brochure also fully describes the geological history of the development of the lone clay deposits. The' new process eliminates the impurities found in natural refractory clays. This results in pure, remarkably uniform refractories which provide longer product life and superior service. Prior to the development of this process, California reserves of super-duty fireclay had been 90 per cent depleted. Now, however, reserves will fulfill the requirements of Western industry for hundreds of years.

A copy of the new brochure can be obtained by writing to Refractories Division, Gladding, McBean & Co., 2901 Los Feliz Boulevard, Los Angeles 39, Calif.

T U B I N G STEELS, The varied requirements of industry have resulted in a bewildering assortment of alloy tubing steels, each with its particular characteristics. Selection of the correct grade of alloy steel for each tubing application, and stocking of adequate quantities of each, pose major problems to design and production engineers. Such probiems can be substantially reduced by standardizing.

A folder recently released by the Tubu-lar Products division of The Babcock & Wilcox Co. discusses two genera! purpose steels which lend themselves very well to such standardization: No. 4340, a through hardening steel, and No. 4620, a case hardening steel. Both are available in tube form in a complete range of sizes. Genera! characteristics and technical data covering these two grades are discussed at some length in the folder.

Kootenai-FIatheod Mineral Resources Survey

Geological mapping for the Kootenai-Flathead mineral resources survey being sponsored jointly by Pacific Power & Light, the Great Northern Railway and the Montana Bureau of Mines and Geology will be extended into additional quadrangles during 1960. Geologists assigned to the project are scheduled to complete the work in the Yaak River quadrangle and also extend their surveying into the Ural and Thompson Falis quadrangles of the Troy-Libby area, according to E , G. Koch, director of the Montana Bureau,

Koch reported a preliminary geological map of the area surveyed in the past year is in preparation and will be published by the bureau along with progress reports covering the area. The map will note all the old mines and mineral prospects of record and establish many geological features not previously mapped, Koch said. It also will show the faults and general geological structure as well as the mineralization of the various sectors.

"Prospectors should find the new geological base maps useful for their detailed field investigations," Koch explained, "because the map will be published on a scale useable for that purpose."

Koch said the first maps issued in 1959 were of the areas surveyed by the project during 1958.

During the past two summers the survey parties from the bureau's field office in Kalispell have mapped all of the Thompson Lakes quadrangel east of Libby and portions of the Yaak River quadrangle north of Libby. In the winters following the field work, the geological information has been correlated with existing data for use in the maps and reports.

Ultimately, the sponsors expect to complete a geological reconnaissance of some 6,800 square miles of Lincoln, Flathead and Lake counties. The work was announced as a five year project when it was started in the summer of 1958.

AEC Buys $2V2 Billon Of Uranium Concentrates

The Atomic Energy Commission purchased some two and a half hillion dollars worth of uranium concentrates from private sources in the 12 years prior to July 1959, and purchases of U.iOs, made hy the A E C ' s Division of Raw Materials, amounted to 114,-400 tons, Wil l iam L . Lennemann revealed in a paper describing sampling of uranium materials and presented at the' 42nd National Meeting of the American Institute of Chemical Engineers, Feb. 23, in Atlanta, Ga.

'Tor the next several years," M r . Lennemann said, "the purchase of U.,Os wi l l be in excess of $500,000,-000 annually." M r . Lennemann is on the staff of the Division of Raw M a terials.

In a general review of the minerals industry, the nation's chemical engineers emphasized the interdependence of the mineral industry and the chemical industry. The non-ferrous mineral processing plants in 11 western states use 1.9 billion pounds of chemicals annuall)'; aluminum from bauxite consumes 1,3 billion pounds of chemicals valued at $20,000,000 ; more than

250 different flotation chemicals totaling 750,000,000 pounds are used annually, and more than 10 million pounds of heavy chemicals, such as sulphuric acid and lime arc consumed yearly. On the other hand, the chemical industry in 1957 p u r c h a s e d $1,175,000,000 of minerals as raw materials, not including fuel. Domestic Uranium Production Statistics for Last Half 1959

The Atomic Energy Commission has announced monthly and total statistics on domestic uranium production for the last six months of calendar 1959. Included are figures on uranium concentrates, ore production, rate of processing, ore fed to process, ore stockpiling, ore reserves, and initial production bonus payments.

Domestic ore reserves were estimated to total 86,100,000 tons on Dec. 31, 1959. In addition, ore stockpiles totaled 1,449,069 dry tons as of Dec. 31, 1959. Ore receipts at all private plants and Government purchase depots in July-December, 1959, totaled 3,614,000 dry short tons; and ore fed to process totaled 3,623,-000 tons, with an average grade of 0.24 per cent UgOs. Uranium concentrates received at the Grand Junction depot totaled 7,899 tons of

UsOs in the six months period. As of Jan, 1, 1960, there were 25

uranium processing mills operating in the western United States, including the Cotter Corp. mill at Canon City, Colo,, which was being enlarged from a pilot plant to a 200-ton-a-day mill. One Wyoming mill (Globe Mining Co.) had started up, but the first concentrate was not delivered to the A E C until early February, 1960. The only government-owned mill, at Monticello, Utah, was closed at the end of calendar 1959. The combined rated daily capacity of the 25 mills was 22,100 tons of ore per day, and their total., estimated capital investment was about $142,-000,000.

Uranium concentrates received at the Commission's depot in Grand Junction, Colo., totaled 7,899 tons of UsOs- The average price paid by the government for the concentrates was $8.79 per pound, or approximately $139,000,000, A n additional 90 tons were produced as a by-product in the chemical processing of phosphate rock in Florida and I l l i nois; and from treatment of Idaho euxenite at the St. Louis plant of Mallinckrodt Chemical Co. Total U . S. production in the six-months period was 7,989 tons.

Zinc-Columbium Coating Solves Oxidation Problem

A civilian metallurgical engineer at the U . S. Naval Research Lahoratory has revealed in the Apr i l issue of Journal of Metals that highly encouraging results have been obtained in experiments seeking to overcome co-lumbium's poor oxidation resistance. Columbium, a lustrous, steel-gray element, has come into increasingly important use for applications in nuclear reactors, jet engines and other high-temperature situations.

The article is by G . Sandoz, Journal of Metals is the magazine of The Metallurgical Society of the American Institute of Mining, Metallurgical, and Petroleum Engineers. During the "Navy Day" program of the Society, Feb. 15, at the A I M E national convention in New York, a Navy spokesman intimated that a major step of highly important potential impact had heen achieved in the efforts now reported by the Sandoz article.

Metallurgists have been frustrated by columbium's poor oxidation resistance and have devoted extensive research to provide this metal with a self-healing coating. Writ ing on the results, M r . Sandoz says:

"Columbium has all the essentials for a good base metal for the development of superior high-temperature al-loj's except for its poor oxidation resistance. Alloy additions confer some oxidation resistance but only at the expense of high-temperature strength or of fabricability of both. It appears that unless and until some oxidation-resistant alloj's are proved out, a parallel effort must be made to develop coatings for those alloys which are strong and fabricable.

"In addition to providing protection against oxidation, a useful coating must also have the quality of repairing (over the temperature range to be experienced by the coated object) any cracks or flaws initially present in the coating or which might be expected to form because of mechanical or thermal strain in service. The U . S. Naval Research Laboratory has developed a tj pe coating to meet these two requirements.

"In its simplest form, this new coating consists of layers of inter-metallic zinc-columbium compounds on the surface of the columbium. The intermetallics may be formed by applying zinc in any of several ways, the simplest of which is perhaps by dipping the columbium in molten zinc. Subsequently, the zinc is reacted

with the columbium substrate in a diffusion-anneal in air in the general range of 1600 degrees F., a treatment which also causes layers of zinc oxide and zinc-columbium oxide to form on the surface.

"As with most intermetaUic compounds, the zinc-columbium intermediate phases are hard and brittle, and they are readily cracked either by mechanical strain or by thermal shock, but they are securely anchored to the columbium substrate and do not tend to spall, and in fact can be dislodged only with great difficulty.

"Such a coating produced from unalloyed zinc and unalloyed columbium protects against influx of oxygen (as judged by microhardness traverses and bend-ductility) for several hundred hours at 1800 degrees F . and for a few days to a few hours in the range 2000 degrees to 2200 degrees F, in still air.

"Preliminary evaluation in hydrocarbon combustion products moving at 500 feet per second and with metal temperature of 2000 d e g r e e s F . showed no indication of oxygen adsorption or other embrittlement in tests of five-hour duration. (Uncoated control specimens are completely converted to oxide in about three hours at these temperatures). The coating thus meets the first requirement-protection against oxidation.

"Perhaps the most strikingly successful aspect of the zinc-type coating is its self-healing abihty. A n opening in the coating to bare columbium is rapidly covered by a thin layer of oxides; zinc coming from the adjacent coating quickly re-forms the intermetaUic layers."

The article says further: "It is intended to publish, at a later

date, details of studies on the effects of third and fourth elements and on other processing variables on the capabilities of this type coating, as well as studies on the crystallography and fundamental physical metallurgy involved."

AAPG-SEPM Meeting Considers Oil Reserves

Members of the American Association of Petroleum Geologists and the Society of Economic Paleontologists and Mineralogists met in joint session Apr i l 25-28 in Atlantic City, N . J. , to examine their most pressing problem: "How to increase our oil reserves ?"

Since President Eisenhower signed a bill giving the states title to submerged coastal lands in 1953, offshore oil has remained a potentially explosive political issue. But new developments may mean that changes wi l l be made from the positions taken in the past by several states.

The continental shelf from New Jersey to Florida, according to the geologists, constitutes a setting favorable for the accumulation of oil and appears to be a likely target for future exploration.

The oilmen also discussed the future of several old producing areas. The Appalachian Mountains, site of the original oil discoveries in the United States and the first wells of


Colonel Drake 100 years ago, was reexamined in an attempt to find new ways to revitalize and expand old fields.

Offshore drilling, successful in recent years in the Gulf of Mexico, has begun in the Great Lakes area. Although operating problems are complex, the geologists believe the favorable marketing conditions in the heavily populated Great Lakes area wi l l provide ample incentive for future offshore exploratory work. Potential oil reservoir rocks underlie all the Great Lakes except Lake Superior.

The oilmen also heard reports on new fields in Mississippi and Michigan, promising areas in the Canadian Arctic islands and along the Florida-Bahama platform.

The world-wide search for oil has recently led petroleum geologists to Africa, where new fields have been explored in Libya, Ghana, and the Ivory Coast, and to Central and South America where exploration may soon lead to new fields in Guatemala, Bolivia, and Columbia.

Reports made on these areas, and on explorations in Australia and Northern Spain, indicate that the O i l Finders are keeping ahead of the oil consumers in building up our oil reserves.

Mixing Ladle in Swedish Plants Described by Journol of Metals

The mixing ladle has provided an interesting new approach to metallurgical problems requiring an intense mixing of liquid iron and an intimate contact between molten iron and solid or gaseous agents, and its achievements at a Swedish plant are described in an article in the January, 1960, issue of "Journal of Metals."

The publication is the official periodical of The Metallurgical Society of the American Institute of Mining, Metallurgical, and Petroleum Engineers. A n article on the process has been written by Sven Eketorp, of the Research Department of Stora Kop-parbergs Bergslags Aktiebolag at Domnarvet, where the mixing ladle has been developed. The reported results have been obtained with a mixing ladle of three metric ton capacity.

"The mixing ladle should be ideal in all cases in which a good stirring effect is wanted," says the author. "In steelworks it wi l l be simpler to use than the rotating furnace formally used in some plants for desulfurization. In foundries it may be used in combination with an acid cupola in which a base iron is made essentially from steel scrap and later carburized, alloyed, and desulfurized in the mixing ladle."

In describing the operation, the article says:

"One of the most important advantages of the mixing ladle is its ease of practical operation. In principle, normal ladles can be used after they have been provided with a conical cover. The cover is necessary during the desulfurization process to achieve reducing conditions, and during oxygen blowing to collect the smoke. During mixing, it is, of course, necessary to have a cover to prevent the pig iron from being thrown out of the ladle. For handling, the ladle is provided with ordinary trunions.

" A n important advantage of the ladle, compared to the rotary kiln, is that it can be made much smaller and, therefore, cheaper, for the same capacity, l l i e mixing ladle, which describes only a small circular path, can be insultated effectively, since stresses on the brick are small."

M r . Eketorp says that mixing ladles with capacities up to 80 metric tons are being planned. He comments, "Metallurgically, the desulfurization in a mixing ladle is the same as in a rotary kiln, but economically it may be somewhat cheaper."

Key to Past Found In Pollen Study at UA

Arizona's prehistoric past is coming to light these days under the microscopes of University of Arizona pollen analyst. D r . Paul S. Martin, and his research associates at the University of Arizona Geochronology Laboratories.

The fossil record they have compiled shows that such animals as horses, mammoths, buffalo and camels ranged through the grassland of the prehistoric southwest.

Contrary to other interpretations, the study of poUen slides at the laboratories shows little evidence of climatic change in the southwest during the last 10,000 years. Dr . Martin said. A colder climate did prevail earlier, he added, when the present Willcox Playa (desert basin) held a permanent lake.

Geochronology is a field of study which uses aU known scientific methods in its attempt to date prehistoric events. The major aim of the U of A laboratories, director Terah L . Spiley said, is to recreate the physical history of Arizona and the region in which it lies.

When asked how his study o± 10,000-year-old pollen serves this major aim, Mart in said, "We have found that arid land pollen profiles can be constructed using the variety of sediments found in this region, and the profiles are an invaluable key to the past."

Dock, Pilot Plant, Ore Deposit Reported by Hanna Mining

Sales of iron ore in Europe was facilitated by tbe opening of the new Rotterdam dock, owned jointlj' by Hanna Mining Co. and Dutch associates. The dock handled 1.1 million tons of ore in 1959. It has a storage capacity of 1.5 million tons of ore and coal.

Hanna Mining and associated companies this spring began construction of a $2 million pilot plant in the Cooley District of Minnesota to test the possibilities of producing high grade iron ore concentrates from semi-taconite, a low grade non-magnetic ore.

In Brazil engineering and cost studies show the possibility of commercial production of ore for export to the U . S. and Europe from the large and exceptionally high grade iron ore deposits held by St. John d'el Rey Mining Co., Ltd. , in which Hanna Mining and associates hold controlling interest.

Moab Uranium Mill Contract Amended

A n amended uranium concentrate purchase agreement has been signed by the U . S. Atomic Energy Comrnis-sion and the Uranium Reduction Co., operators of the 1,5,00-ton-a-day uranium processing piill at Moab, Utah, it was announced by the Grand Junction Operations Office of the Commission, ; 3 ,-

The amended ;a^reement extends the contract to. Deie. 31, 1966, and provides for conversion of one of the mill's acid circuits Jo. a carbonate^ circuit capable of -treating the hig|a-Iime ores of the dis,t("ict. It also proyjd.es ^ firm market for,n|Umerous.independent ore producers whose (properties hereafter are "dedicated" to the Moab mill.

By converting one circuit to a carbonate circuit, the Moab mill henceforth wi l l provide a market for high-lime ores found in the Big Indian district. The inclusion in, the amended contract o f ' f i r m allocations to ore producers wi l l .ipake it possible for the mines to operate at a rate consistent with good piining practice for economical extraction of ores.
