  Extraction Of Copper Mining Concentration Smelting

  Iron in Chalcopyrite is removed as Iron silicate slag Most of the sulfur in Chalcopyrite turns into Sulphur dioxide SO 2 The reaction of these processes can be written as 2CuFeS2 2SiO2 4O2 → Cu2S 2FeSiO3 3SO2 The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance
