Flotation machine is the main equipment of mineral processing equipment, the majority are screened for metal ore by flotation machine. Talc is an aqueous silicate layered mineral with ionic bonds in the layer. Therefore, the surface is non-polar and highly hydrophobic. Talc hardness is small, there is slippery, the density of 2.7-2.8g / cm3, shiny glass, oil sheen was a dense block, often coexist with magnesite, hematite. Talc has a flaky shape, a block shape, a mixed shape, etc., and different structures have different properties and uses. Because talc has the characteristics of lubricity, flexibility, fire resistance, insulation, chemical stability and strong adsorption to oil, it is widely used in paper, ceramics, rubber, paint, medicine, casting and other industrial sectors. Fine grinding is an important task for talc flotation. The talc product has a particle size of -74 microns, 98%, -44 microns, 98.5%, and -44 microns, 99.5%, and each contains a considerable amount of 15-35 micron micropowder, talc floatability. Better, the process structure is simple, generally through 1 rough selection, 3-4 selections and 1 sweep selection. Flotation can be carried out at pH = 13 to neutral medium. The flocculating agent may be a short chain cationic amine, a petroleum sulfonate, a sulfate ester of a higher alcohol, a nonpolar anthraquinone oil or the like. The blade-like talc only requires a foaming agent. Fibrous talc requires the addition of an amine-based flotation agent for flotation. Flotation is difficult when the ore contains an oxidant and the talc particles are coated. It has been reported that reducing the pH to 6 increases the selectivity of flotation. Adding an appropriate amount of sodium silicate during flotation can separate the clay from the iron oxide and improve the separation effect.
