In this process, Cu2S behaves as reducing agent. 2Cu2S+3O2+heat2Cu2O(s)+2SO2(g) 2Cu2O+Cu2S+heat 6Cu(s)+SO2(g) In electrolytic refining of copper, the

Copper extraction

History

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
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), th
