Kaolin is widely used in the production of ceramics and construction materials, where it enhances the strength, durability, and workability of products like bricks, tiles, and cement.

Kaolin processing waste can be activated by thermal treatment at low temperatures in order to obtain the active starting materials before the preparation of geopolymers via the same method as kaolin. The active starting materials can easily dissolve in an alkaline activator solution, and it will act as a geopolymer precursor in the ...

The main commercially important kaolin resources are the primary deposits in Cornwall and the sedimentary deposits in South Carolina and Georgia in the U.S.A. Annual world production is about 18 Mt (1 t = 103 kg). In 1981 the U.K. production was 2.6 x 106 t of which about 77 % represented paper filler and paper coating grades. About 15% of the U.K. …

The in-situ crystallization method occupies an important position in the field of new zeolite with its unique advantages. The basic technological process flow is: kaolin raw material-spray molding (spray microspheres)-roasting (calcined microspheres)-crystallization (microsphere precursor)-post-processing- the finished product.

Kaolin: processing, properties and applications. Kaolins are white raw materials, their essential constituent being fine grained white clay, which are amenable for beneficiation that make them ideal for an assortment of industrial applications. Kaolin deposits can be classified into two types, primary (residual) and secondary (sedimentary).
