    2015-7-26 · Copper can be extracted from non-sulphide ores by a different process involving three separate stages Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction.

  • Extraction Of Copper Mining Concentration Smelting

    Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica) calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces calcium carbonate is added as a flux to create the slag.
