Nigeria's kaolin has been found to meet the requirements of industries such as paint, ceramic, rubber, paper, pharmaceutical, and cosmetics industries after beneficiation or calcination.
However, the application of kaolin for material development and production has been restricted to the laboratory and not in large-scale industries. Nigeria's kaolin has been found to meet the requirements of industries such as paint, ceramic, rubber, paper, pharmaceutical, and cosmetics industries after beneficiation or calcination.
Kaolin dry beneficiation process. The kaolinite dry mining process is a simple and economical process. The ore is crushed to 25.4mm by a hammer crusher and fed into the cage mill to reduce the particle size to 6.35mm. The hot air in the cage mill reduces the moisture of the kaolin from about 20% to 10%. The crushed ore is further …

The results obtained in the present study are quite promising. It was possible to diminish Fe2O3 and TiO2 contents improve the brightness index of kaolin concentrate ...
Abstract. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, in the form of kaolinitic clay, and also to increase the alumina content. Additionally, reduction in iron content, particularly in the form of goethite, and reduction of organic carbon can also increase the value of the bauxite product.
