摘 要：<正>To fulfill the increasingly higher requirements on thequality of kaolins from industries, the purification of kaolins has becomemore and more important. Kaolins from different mines were studied withthe aim to remove the various impurities. The mineralogical studies on thekaolins indicated that kaolinite and the major gangue minerals in the orewere all very fine. Therefore, it was difficult to separate kaolinite fromthe gangue minerals by conventional mineral processing techniques,such asgravity concentration, magnetic separation and flotation. Techniques forfine particles processing, i. e. selective dispersion and flocculation weretried to purify the kaolins. The experiments were first carried out withpure minerals of kaolinite and the gangue,minerals to study the dispersionand flocculation characteristics of the different mineral suspensions undervarious conditions. The key factors affecting the dispersion and floccula-tion of the minerals in water were the pH of the suspension, the type anddosage of t
