extraction of copper from its ore for tin in russia

Copper extraction

Copper extraction. 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.
