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

Copper production environmental impact

The copper-bearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning (SX-EW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electro-chemical deposition. It takes about a week before the cathode is ready to be removed from the tank so the
