Copper extraction - Wikipedia

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

MANAGERIAL REVIEW Examining the copper value chain

Mining sulfidic ores The first step in the value is mining the ore. As the copper content of the ore has only 0.3-1.0 % copper, it is enriched by flotation to a copper concentrate with about 25-35 % copper to avoid processing of a high amount of gangue material. So copper concentrate is the first traded product with a value. There are mining
