It is the process used in the metallurgy of copper. It involves the reduction of molten mattee (mixture of cuprous sulphide and ferrous sulphide) obtained after smelting of copper pyrites ore in a Bessemer converter.
The molten mattee is taken in Bessemer converter and heated by blowing hot blast of air and sand through tuyeres.
1. Air oxidizes iron sulphide to iron oxide and SO2.
4. The cuprous oxide so formed reacts immediately with remaining cuprous sulphide to form metallic copper.
2Cu2O + Cu2S ---------> 6Cu + SO2
Bessemerisation also used to convert pure iron to steel.
