Abstract

Clay, e.g. kaolin or china clay, is treated to remove titanium mineral impurities by mixing with a suspension of the clay in water a flotation assistant consisting of a water-soluble salt of an alkaline earth (including magnesium) metal or a metal having a sp. gr. greater than 4, an alkali to raise the pH to about 9, a collector for impurities, a frothing agent and subjecting the suspension to a froth flotation process. The suspension may first be deflocculated by adding a deflocculating agent, e.g. sodium silicate, and after adding all the reagents the suspension may be conditioned by agitation. Before flotation is commenced the suspension may be diluted with water to a solids content of 15-20% w./v. The collector for impurities may be oleic acid, the frothing agent pine oil and the alkali ammonium hydroxide. The compounds specified as flotation assistants are water-soluble salts of Ca, Sr, Cu11, Fc11, Pb11, Mn11, and Zn and especially lead acetate, lead nitrate and barium chloride.ALSO:Clay e.g. kaolin or china clay, is treated to remove titanium mineral impurities by mixing with a suspension of the clay in water a flotation assistant consisting of a water soluble salt of an alkaline earth (including magnesium) metal or a metal having a sp.gr. greater than 4, an alkali to raise the pH to about 9, a collector for impurities, a frothing agent and subjecting the suspension to a froth flotation process.
