  • Seven Common Froth Flotation ProcessesXinhai

    Froth flotation process is a kind of mineral processing technology that uses the flotation reagents to separate the ore according to the physical and chemical properties of the surface of the ore. The froth flotation process is to grind the mineral to the floating requirement adjust the pulp concentration and add the flotation reagents then inflate the air to make the mineralized froth separate.

  • Flotation ReagentsMineral 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.
