When the pH is 8-11, adding alkaline metal ions such as Ca2+ and Mg2+ to the kaolin slurry can selectively coagulate iron and titanium impurities, and then use weak anion polyelectrolyte for selective flocculation. This process requires pulp concentration to be lower than 20%, and dewatering is required for subsequent operations.
