Extraction Of Copper Mining, Concentration, Smelting ...

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 appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air.
