In roasting, air in large amounts, sometimes enriched with oxygen, is brought into contact with the sulfide mineral concentrate. This is done at elevated temperatures when oxygen combines with sulfur to form sulfur dioxide and with the metal to form oxides, sulfates, and so on.

In flash roasting, the preheated ore is injected through a burner. This process is most appropriate for the roasting of sulfides, which oxidize exothermally and require no additional fuel. In flash roasting, the benefits of a counter flow operation are partially lost. The use of fluidized beds for roasting fine concentrate is obviously ...
