Flotation Reagents - Mineral Processing Metallurgy

2016-06-08  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.

Flotation Frothers - Frothing Agents

2015-06-22  The next reagent that is added is the Flotation FROTHER. The frother strengthens the surface tension of the air that is injected into the flotation cell. As the air rises in the shape of bubbles, they come into contact with the mineral laden collector which attaches itself to the air. The bubble will continue to rise until it reaches the surface and flows over the side of the cell. While the ...
