    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.

    Overdoses of frother should be avoided. up to a certain point increasing the amount of frother will gradually increase the froth produced. beyond this, however, further increases will actually decrease the amount of froth until none at all is produced. finally, as the excess works out of the system the froth runs wild and this is a nuisance until corrected.
