The effect of pH and polymer type on efficiency and mass recovery of the selective flocculation were studied. In the pH range studied (from 7 to 11) the polymer SFA150 with high anionic charge (50%), was shown to be inefficient in removing the TiO 2 present in the kaolin. The titanous impurities were significantly removed by the use of polymers with weak anionic charges (10%) in alkaline medium.

To remove a colored titania impurity from kaolin clay, the impure clay is formed into a welldeflocculated aqueous slip. A small amount of a soluble source of polyvalent cations,, calcium chloride, is dissolved in the slip. An anionic organic polyelectrolyte is added and the slip is agitated until titaniarich flocs form and settle out from the deflocculated slip.
