Scoping By S. Munyaradzi
To split the whole project into workable phases
To identify the practical needs of the project
To identify the skeleton labor required to kick start the project
To identify a partner ( Eng. Contractor) competent enough to assist
To come out with the direct costs of the project
At the end of the exercise, we must be able to
identify the different phases of the resuscitation programme
to name a partner
quantify the physical requirements of the project
to value the requirements ( specific costs)
to verify the labor we require
to kick-start the reconstruction of the plant
The sands retreatment plant refurbishment and eventual operation is the first part of a holistic ‘C’ Mine Revival Plan.
We intend to revive the whole plant, effecting repairs to machinery, replacing broken piping, fitting new pumps and motors
We also intend to repair and replace all electrical wiring and switch gear
Effect repairs to the lifting equipment Re-line the Ball Mill Repair and replace Hydrocyclones and desanding
cones construction of the feed hopper
Effect repairs and services to the knelson concentrator
effect repairs to the amalgam barrels and copper plates
Replace the pinion gear
fabricate motor-gearbox coupling
Recondition mill white metal bearings
Repairing of all mill sumps
Cleaning out of all containers, i.e. , thickener, leach tanks and the carbon tanks
Removal of all junk metal from the tanks Repairs of the overflow line to the thickener Repairs to the thickener drive mechanisms Repairs to the thickener rakes Repairs to the thickener under-flow line Repairs to the thickener U/F pump and
motor Reconstruction of the leach tank feed line
repairs the thickener walkways and platforms
repairs to the leach tank platforms and walkways
Installation of mechanical agitators in leach tanks complete with motors
construction of a cyanide mixing tank
replacement of leach tank interconnectors
Installation of the 3/2 transfer pump and motor and pipe lines
repair all agitators in carbon tanks
repair all platforms and walkways on carbon tanks
replace all pipelines on the carbon tanks
repair the carbon trommel screen and motor
repair and replace all electrical wiring and switchgear in the section
reconstruct the carbon scavenging screen
installation of the slimes dam pump and pipe line
repairs and reconstruction of the current slimes dam
repairs of the catwalk
repairs of the penstock
repairs of the barren water line
repairs of the barren water tank and pump and motor
protection of the environment is essential at every point of the project
Rehabilitation of the laboratory
purchase of a compressor
purchase of front-end loaders
purchase of dump trucks
purchase of a 450 kva Generator set
Carbon retention screens
Single stage or 2HD Mono pumps and motors
And others
This phase involves what is happening on the ground right now:
Cleaning muck out of all containers repairs to the pinion gear refabrication of the gear box coupling relining of the ball mill installation of the discharge pumps repairs of the hydrocyclones repairs of the electrical wiring and
switchgear
repairs to the lifting equipment
construction of the main feed hopper
repairs and replacement of all pipe works
repairs of all platforms and gangways on the leach and adsorption section
repairs to the thickener equipment
Installation of mechanical agitators complete with motors in the leach tanks
fitting of all pumps in the two sections and piping
Repairs to all agitators in carbon tanks Repairs to all electricals Installation of carbon retention screens Repairs of the carbon trommel screen Repairs to all piping Construction of a vibrating screen for carbon
scavenging c/w motor Installation of a slimes dam pump and motor and
pipeline Repairs to the slimes dam cat walk Repairs and reconstruction of the slimes dam
walls
Replacement of the barren water line
Replacement of the return water pump and motor
Environment protection essential at every stage of the project
This is a 6 ½ * 8 ft Ball Mill. It requires
relining
and the relining costs $75,000,00
Feed hopper must be constructed at a cost to be advised by the contracting partner
An initial estimate is valued at $10,000,00
The refabrication of this unit is estimated at $5,000,00 according to a quotation from Nimr and Chapman
This unit is estimated to cost at $31,000,00 according to quotation by Nimr and Chapman
This is estimated at $7,000,00
This unit is estimated at $7,000,00
Estimated to cost$7,000,00
Estimated at $15,000,00
Estimated at $3,000,00
Estimated to cost $3,000,00
All slurry pumps have been estimated at $32,000,00
single stage KSB pump or 2HD pump estimated at $3,000,00.
Material for grating has been estimated at $20,000,00.
Estimated at $20,000,00.
