concentration of copper minerals

Copper Mining and Processing Processing of Copper Ores . Copper oxides are more abundant near the surface, but are considered low grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit.

purification of copper by electrolysis metal extraction

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.
