Copper Mining and Extraction: Sulfide Ores. Copper has a remarkable combination of properties. It is a good electrical and thermal conductor. It is ductile and it can prevent bacterial growth (see Copper: Properties and Applications ). As with all world resources, the supply of copper from the ground is limited.

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.
