Flotation Since the natural floatability of talc good, thus with a hydrocarbon oil to a flotation collector. The collector used is kerosene, oil as flotation frother. Of methyl isobutyl drunk (MII3C) foam generated It is brittle and easy to obtain high-quality concentrate. The talc flotation process is relatively simple, only one rough selection and sweeping, and 3-4 times of selection can obtain the final concentrate, but the talc concentrate is fine and the dehydration is difficult. 2. Hand selection Hand selection is based on the slippery nature of talc and gangue minerals. The talc has good slipperiness. The higher the grade, the better the slipperiness. It is easy to identify by hand. Most of the domestic talc mines are used to produce high-grade slip. In recent years, foreign countries have successfully researched a talc sorting machine called a riprap machine, which can separate the talc from the gangue according to the difference in ore friction coefficient, thereby realizing the mechanization of talc hand selection. In short, the high-grade talc generally adopts the hand selection method or the riprap machine. Only the fine powder below the production level is used for the flotation method. In order to ensure the whiteness , magnetic separation must be performed to remove the dyed mineral.
