FLOTATION METHOD FOR REMOVING COLORED IMPURITIES FROM KAOLIN CLAY |
摘要 |
An improved method for purifying titania contaminated kaolin clay by froth flotation which features the use an hydroxamate flotation collector at a neutral or mildly alkaline pH wherein a slurry of the impure clay is conditioned for the flotation step in a baffled conditioning apparatus provided with mean for imparting sufficient mechanical energy to heat a dispersed slurry of the impure clay before flotation. |
