Mining and Ore Processing :: WorstPolluted : Projects Reports

Mining and ore processing occurs throughout the world and consists of extracting minerals, metals, and gems from surrounding earth and ore. Industrial mines vary in size, with some being quite small operations and others very large. Many large scale mines also have ore processing facilities where extracted ore is sent for.

Copper extraction Wikipedia

As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then.
