extration of copper from its ore

Extraction of copper from copper pyrites .

Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. 1. The volatiles like sulphur and arsenic escape as gases S + O 2> SO 2 4AS + 3O 2>2AS 2 O 3 2. Copper pyrites is converted to a mixture of Cu 2 S and FeS 2CuFeS 2 + O 2
