Kaolin clay is also known as China clay, White clay, and Kaolinite clay. The main component of kaolin clay is the mineral kaolinite, which is a layered silicate mineral. Kaolin clay is found all over the world, but the name comes from Gaoling, the Kaoling mountains in China, where it was mined for centuries.
Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals with the chemical composition Al 2 Si 2 O 5 is a layered silicate mineral, with one tetrahedral sheet of silica (SiO 4) linked through oxygen atoms to one octahedral sheet of alumina (AlO 6) octahedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.
Therefore kaolin is widely used in papermaking, ceramics, rubber, chemicals, paints, pharmaceuticals and defense industries, ect. Kaolin has wide application in the paper industry. There are two main areas, one is filler in paper making process, and the other is pigment in used in coating industry.
Kaolin is a hydrated aluminum silicate obtained by mining naturally occurring mineral deposits. Large deposits are found in Georgia, USA and in Cornwall, England. Mined kaolin is powdered and freed of coarse, gritty particles either by elutriation or by screening.

The processing route suggested has the potential to produce cement powder. This process uses the geopolymerization reaction. Calcined kaolin was firstly alkaliactivated using mixture of NaOH and Na 2 SiO 3 solution and then heated in oven to get a solidified product. This was crushed into powder.
The present invention provides a process for whitening kaolin contaminated with chlorite/biotite micas. The process comprises the steps of contacting the kaolin contaminated with chlorite/biotite micas with an aqueous acid solution to convert the chlorite/biotite micas into kaolin and one or more dissolved metal salts, and separating the kaolin from the dissolved metal salts.
Commercial grades of kaolin are supplied and transported as dry powder, semidry noodle or as liquid slurry. It is used in ceramics, medicine, bricks, coated paper, as a food additive, in toothpaste, as a light diffusing material in white incandescent light bulbs, and in cosmetics.
Kaolin process flow which is important to kaolin processing mainly consists of the following steps:crushing, precipitating, classifying, calcining crushing process which is the first step of the process flow has impact on the quality of kaolin powder, hence customers prefer to choose vertical mill with superior performance to process kaolin.
