    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 SFA-150 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.
