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.

May 07, 2018· Flotation . BASF's Lupromin® flotation range includes collectors for non-sulfide ores, frothers, dispersants and modifiers that are applied in this widely used process, separating minerals from gangue by creating favorable differences in media hydrophobicity.
Other Industrial Minerals. Discovering the true potential of an industrial mineral deposit is no small challenge. ArrMaz's metallurgical lab has the experience and expertise to test new chemistries on your mineral deposit to help you understand its true value.
Mineral processing equipment includes gravity separation equipment and flotation equipment; gravity separation equipment: jig. Only jig can deal with the coarse fluorite ore. Fluorite flotation equipment includes crusher, ball mill, flotation machine etc. Jaw crusher is the primary crusher. It is used in fluorite coarse crushing process.
The sulfide ore contained in fluorite (fluorspar) is floated with xanthate collector, and then fatty acid collectors float fluorite (fluorspar). In flotation of fluorite (fluorspar), it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the quality of fluorite (fluorspar) concentrate.
