Advances In Sulphides Flotation

flotation of nisulphides

Traditional sulphidisation flotation techniques, which are widely used on copper oxide ore, can not be used in sulphide/oxide blends for simultaneous sulphide and oxide copper flotation as the sulphidising reagent will suppress the flotation of sulphide minerals as shown within this case study.

Flotation Reagents - Mineral Processing & Metallurgy

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.
