Kaolin, also known as China clay, kaolin is theoretical formula Al 4 [Si 4 O 10] (OH) 8, the chemical formula Al 2 Si 2 O 5 (OH 4) or Al 2 O 3 2SiO 2 2H 2 O. The theoretical chemical composition is: Al 2 O 3 39.5% , SiO 2 46.54% , H 2 O13.56% , but due to the influence of various impurities, it contains Fe 2 O 3 , TiO 2 , CaO, MgO, K 2 O, Na 2 O and other components. Kaolin is an aluminum silicate mineral content is relatively average. At present, the main direction of comprehensive utilization of kaolin is kaolin finishing and deep processing. Finishing refers to the treatment of purification , decomposition, refinement and modification without changing the chemical composition and crystal structure of kaolin . Deep processing refers to the complete destruction of kaolin under certain physical and chemical conditions, transforming it into a crystalline or amorphous new product, or by separating the valuable components aluminum and silicon by acid decomposition, thereby producing more Aluminum salts and their aluminum compounds and silicates and their silicon compound products. This project is mainly devoted to the deep processing of kaolin. Now it has developed aluminum series products such as polyaluminum chloride, polyaluminum silicate sulfate, high purity aluminum ammonium bismuth , high purity ultrafine alumina, etc. Silicon series products such as sodium silicate, active Silica, etc. These products are widely used in water treatment, fine ceramics, rubber, plastics and other industries. Products can be independent, and can be transformed into each other, flexible and adaptable, can fully adapt to market needs, and can obtain higher added value. Therefore, the deep processing of kaolin has obvious economic benefits and broad market prospects.
