Beneficiation and Evaluation of Mutaka kaolin. close to that of ideal kaolin. Keywords Beneficiation, Kaolin, Mutaka kaolin, Particle size distribution. 1.0 INTRODUCTION Kaolin is a soft, white, plastic clay consisting principally of kaolinite, which is a well ordered hydrated aluminium silicate Al2Si2O5OH4.
Kaolin is coated with coupling agent to improve its addition in plastic rubber, which is used to treat kaolin filler for rubber and plastic. The mineral processing of kaolin can be divided into dry process and wet process. According to the properties and uses of kaolin, find suitable beneficiation methods to improve economic benefits.
beneficiation exercise improves the kaolin sample to a very high grade with a chemical composition close to that of ideal kaolinite. The major impurity after beneficiation, iron oxide, was further reduced by acid leaching. Results show that the properties of the final product are close to that of ideal kaolin.
