  • 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 sulfide Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

  • Copper extraction - Wikipedia

    Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag The amount of copper lost as oxide copper increases as the oxygen potential of the slag increas.
