Manufacturing Process of Copper. Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.

The main methods of processing copper oxide ore are: Flotation and Leaching. For copper oxide ore with large mud content and easy to mud, the traditional sulfidation flotation recovery rate is low, and it is difficult to solve the problem of mud interference; the stirred leaching method has the advantages of short leaching cycle and high copper leaching …

To be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite (Cu 2 S), Chalcopyrite (CuFeS 2) and Covellite (CuS) . In the concentrating operations these minerals are separated from the gangue material of the ore, that might contain as little as 0.5% copper to form a concentrate ...
