Copper Ore Leaching Electrolytic

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult to concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro winning (EW). It can produce either copper cathode or copper sulphate crystal.

    Aug 01, 2020 Ninety percent of global copper resources are sulfide ores, where most of the copper is in the form of covellite (CuS), chalcocite (Cu 2 S), chalcopyrite (CuFeS 2), and bornite (Cu 5 FeS 4). Covellite and chalcocite are surface deposits and can be treated economically, but these resources are largely exhausted.About 80 of the world's copper from ore is produced by concentration smelting refining of sulfide ores.

    The Recovery Of Copper In Sulphide Ores By Roasting

    Heap leaching, or dump leaching, is a conventional technique for extracting metals such as copper from low grade ore bodies. The metal is recovered from its oxide and or sulphide ores in two stages. The first stage involves creating conditions in which the metal passes into solution.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.
