|
Ore
|
a rock that contains a large enough concentration of a particular mineral to be profitable for extraction
|
|
|
externality
- do not use books definition- |
A negative impact caused by the production of a good that is not incorporated into the price of the good. The negative impacts are often felt by a different group than the producer of the good
|
|
|
acid mine drainage
|
Pollution caused when sulfuric acid and toxic dissolved minerals, such as lead, arsenic, and cadmium, wash from mines into nearby lakes and streams. Increases in rainstorms especially in Spring.
|
|
|
tailings
|
Waste after ore mining and usually left in giant piles on the ground or in ponds near the processing plants; contain toxic chemicals like cyanide, mercury, and sulfuric acid.
|
|
|
coltan (columbite-tantalite)
|
a valuable black mineral combining niobite and tantalite; used in cell phones and computer chips.
|
|
|
non-metallic mineral-
|
Sand, stone, salt, and phospates, not good conductors of heat and electricity
|
|
|
metallic mineral
|
Fe iron, AL aluminium, Cu copper, which are malleable, lustrous, and good conductors of heat and electricity
|
|
|
4 reasons why mineral prices declined over the last half of the 20th century.
|
1. Discovery of new mineral reserves
2. Better technology for extraction 3. Substitution (e.g. fiber optics instead of copper) 4. Recycling |
|
|
5 environmental Impacts of mining
|
1. Habitat Loss (deforestation) Ex. Mining in Amazon
2. Water Extraction: pumping water out of the mine 3. Water pollution: 11,800 miles of streams polluted by mining in US Acid mine drainage: Sulfide minerals create acid, contains heavy metals (mercury, cadmium, arsenic 4. Energy consumption: Processing ore requires lots of energy 5. Release of sediment from hydraulic mining 6. Tailings disposal: 80% of mined ore consists of impurities that become waste after processing. |

|
Pros
of the United States importing metals from other countries. |
Pros:
1) Attracts investment, jobs, and revenue for developing countries 2) Export better technology & Reduce environmental impact to the U.S 3) Lower labor costs & Cheaper goods |
|
|
Cons
of the United States importing metals from other countries. |
1) Lax environmental laws overseas: Are we “exporting pollution”?
2) Geopolitical - dependence on foreing material 3) Environmental justice issue: Poor are often the most impacted |
|
|
2 environmental problems associated with mining in California and what kinds of mining activity caused those problems.
|
-Sediment displacement from hydraulic mining.
-Water pollution, Mercury and cyanide in the water from gold mining. -Tailings disposal, 80% of mass mined is waste. In Klamath Mountains Ca |
|
|
2 geographic locations where mining in a developing country has had a negative environmental impact, and name the mineral(s) involved.
|
Congo - coltan / important component in cell phones
Papua New Guinea -Copper mining / acid rain killing forest |
