Extraction Of Copper | Mining, Concentration, Smelting
Iron in Chalcopyrite is removed as iron silicate slag. Most of the sulphur in Chalcopyrite turns into Sulphur dioxide (SO 2). The reaction of these processes can be written as: 2CuFeS 2 +2SiO 2 +4O 2 → Cu 2 S+2FeSiO 3 +3SO 2. The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and ...
