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.
