Roasting is the conventional technique used in the pyrometallurgical processing of copper, nickel, and zinc sulphide concentrates. During roasting, the sulphur is removed by adding air and simultaneously heating and drying the concentrate to achieve sulphur content favourable for smelting. The sulphur is released as sulphur dioxide.
