extraction of copper in mining

Electrolytic Refining Mining Fundamentals

Copper The extraction of copper from other ores through electrolysis involves the deposition of copper on the cathode, and using lead-coated anodes. The purification of copper involves the use of copper sulfate solution as the electrolyte, high purity copper strips as cathodes, and impure copper anodes.

4a. The extraction of copper from copper ores and its purification by electrolysis. Copper is well below carbon (less reactive) and so can be displaced by carbon from its compounds eg copper oxides or sulfides. However, in practice, modern copper smelters can actually manage the extraction without using carbon (coke) and then electrolysis is usually used to purify the impure copper from the smelter.
