Purifying Kaolin: Removing Iron Impurities Made Easy
The kaolin coagulation or flocculation method mainly removes iron and titanium impurities in kaolin. The pulp concentration must be lower than 20%, so a large amount of water needs to be released in the subsequent process. Kaolin is wide application but often contains iron impurities that detract from its effectiveness.

Source of Unimin kaolin rheological variation–Ca2+ concentration
Conclusions. Unimin kaolin has been identified to carry sufficiently high concentrations of Ca 2+ cations that have caused its zeta potential-pH, yield stress-pH and consolidation behaviors to be varied to that of low Ca-Riedel kaolin. While Mg 2+ cations could also affect these behaviors of kaolin slurries, it is, however, not in …
