    Jun 15, 2018 Size-by-size Cu-metal analysis of the flotation feeds prepared by different grinding procedures showed that for LJ ore dry grinding resulted in higher Cu grades in the coarser fraction and correspondingly lower Cu grades in the finer size fractions. For DX ore grinding procedures had little effect on Cu distribution among size fractions.

    First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).

    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.
