  • How is copper extracted from a low

    (ii) Copper matte contains Cu 2 S and FeS. In the blast furnace, copper matte is added with powdered coke and silica. The oxidation of ore takes place in this process. As a result, cuprous oxide and ferrous oxide are produced. The role of silica in this process is to remove the iron oxide obtained as 'slag'.
