Kaolin, also known as china clay, is a natural clay formed by chemical weathering of aluminium silicate minerals like felspars through a complex sequence of events. It is relatively pure clay predominantly consisting of kaolinite (Al2Si2O5(OH)4), associated with other clay minerals like dickite, halloysite, nacrite and anauxite.
Sep 01, 1991 There are two basic methods of processing kaolin, a dry method or a wet process (Guillet and Kriens, 1984). The dry method is called air flotation which separates the clay from contaminants. The wet method produces water washed clay where the clays are fractionated, beneficiated or otherwise modified from their orig- inal state.
Kaolin, also called china clay, soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, and many other products. Kaolin is named after the hill in China (Kao-ling) from which it was mined for centuries.

In the wet processing of kaolin clay, the clay crude is initially deflocculated (dispersed) with a synthetic watersoluble salt having an organic polymeric anion. The deflocculated clay then undergoes further processing, including fractionation, floccing with an agent which must include alum, bleaching, filtration, rinsing and re-deflocculation.

The ratio of waste to clay is variable, but overall is in the order of 1 to 1.5. Ball clay undergoes limited processing. Most is size reduced and some 70% is sold in this form. This allows the clays to be more easily handled and blended. The blending being essential to optimise clay use and to consistently meet customer specifications.
