Kaolin powder process solution

What is Kaolin?

Kaolin is a clay mineral, part of the group of industrial minerals with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO4) linked through oxygen atoms to one octahedral sheet of alumina (AlO6) octahedra. Rocks that are rich in kaolinite are known as kaolin or china clay.

Processing Technology

Typically, presence of iron imparts a pink colour to the matrix. The mined and sorted kaolin is then subject to processing by a wet route to produce processed kaolin with desired properties for various applications.
