Flotation Reagents Mineral Processing amp 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 nonfloatable 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
