environmental impact of gold ore and copper ore mining

Copper & the Environment Copper Mining In A Cotton Field?

With conventional mining, large amounts of rock are moved to expose the ore, which then has to be mined so the copper can be extracted. The in situ process avoids almost all this work; ore is leached right where it is. The in situ mine consists of a series of injection wells and recovery wells.

Environmental impact of iron ore mining

Mining and processing. If the ore contains less than 60 percent iron, it is usually beneficiated to an iron ore concentrate typically containing greater than 60 percent iron. This is done by separating the iron minerals from the valueless minerals, usually by magnetic, gravity, or froth floatation.
