    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 containing 27 to 36% copper.

    Copper Mining and Extraction Oxide Ores

    Copper is refined from ores in the ground, either through underground or open pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores (1114), but is introduced here because an important by product of this process is used for the extraction of oxide ores.

    Innovations Introduction to Copper Mining & Extraction

    The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

    The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example FeO(s) + SiO 2 (s) FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.
