Ores Mineral deposit from which a metal or
nonmetal can be profitably extracted
Native Elements Native element minerals are those
elements that occur in nature in uncombined form with a distinct mineral structure.

Mineral ores formation Cooling of magma
When magma cools dense material sink to the bottom
Contact metamorphism Magma comes in contact with rocks Rock changes Dissolve minerals forming veins
Mineral ores formation Placer deposits
accumulation of valuable minerals formed by gravity separation during sedimentary processes.
Dissolving Precipitating Water dissolves minerals Water evaporates and minerals precipitate out
Homework Study Table 11-1 (p. 197). Name 4
metallic minerals and 4 non-metallic minerals that you have used in the last few days and describe what they were used for.
Mining video Revised definition of a ore:
Any mineral or MATERIAL that has economic value
Types of ores mined from Earth Metallic
Copper Gold Silver Graphite
Non-metallic Diamonds/ gemstones Salt Gypsum
Fuel Oil Natural gas Coal Uranium
Michigan common ores Aggregate
Sand, gravel Used for construction
Halite / Brine Salt/ Salt water
Used for food Deicing (lowers freezing point of water)
Iron ore Used for industry
Copper Wires Coins
Fossil fuels Organic material that has stored energy
Made of hydrocarbons (consisting entirely of hydrogen and carbon)

Fossil fuels non-renewable Can not be replaced in our lifetime
MILLIONS OF YEARS to form
When fossil fuels are burned Combustion reaction CO2 and H2O vapor
Negative impactsMining/ processing Fossil fuels
Fuel resources Coal:
Carbonization: dense forests in low-lying wetland areas, buried under mud and soil.
Uses: Primarily burned for electricity
Efficiency: <47%
Environmental effects: Acid rain from high sulfur content Greenhouse gases Smog
Fuel resources Crude oil:
formed when large quantities of dead organisms, are buried underneath sedimentary rock and subjected to intense heat and pressure.
Uses: Transportation Petroleum products
Efficiency: <67%
Environmental effects: Greenhouse gasses Oil spills Drilling
Fuel resources Natural gas:
formed when layers of buried plants and animals are exposed to intense heat and pressure over thousands of years.
Uses: ranges and ovens, gas-heated dryers,
heating Efficiency:
<90% Environmental effects:
Greenhouse gasses
Fuel resources Uranium:
Radioactive element, mined as a ore. Uses:
Nuclear fission Splitting of a nucleus of an atom
Power Efficiency:
<99% Environmental effects:
Radioactive waste Mining
