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.

Sulfur is evolved by most copper extraction processes. The most common form of evolved sulfur is sulfur dioxide (SO 2) gas from smelting and converting. It must be prevented from reaching the environment. Most smelters capture a large fraction of their SO 2. It is almost always made into sulfuric acid, occasionally liquid SO 2 or gypsum. This ...
