Processing of Kaolin: It is first processed dry, which includes crushing, drying and softening, the product of which is kaolin used in ceramics, paints and rubber. Wet processing, or rinsing with water, separates non-kaolin minerals from the conductive liquid, at which point is obtained as a filler and coating.

Kaolin clay (or China Clay, ) is white clay mostly composed of kaolinite, which is a hydrated aluminium silicate. The kaolin geology process relies on chemical weathering, which transforms hard granite into soft granite ("kaolinisation"). Because of the numerous inherent properties of kaolin, kaolin uses are very diverse.

Kaolinite is described as a 1:1 clay mineral consisting of two layers joined through an apical oxygen. One layer is known as the siloxane layer and consists of silicon tetrahedra joined in an hexagonal array. This layer is coupled to a gibbsite-like layer consisting of octahedral aluminium bonded to four OH units and two oxygen atoms.
