Extraction of copper from copper pyrites (CuFeS2

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 gt; SO 2 4AS + 3O 2 gt;2AS 2 O 3 2. Copper pyrites is converted to a mixture of Cu 2 S and FeS

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
