pyro metallurgical extraction of copper from sulfide ores

Copper extraction - Wikipedia. Copper extraction refers to the methods used to obtaining copper from its ores. The conversion If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.
