Kaolinite is a layered silocate made of alternating sheets of octahedrally coordinated aluminum and tetrahedrally coordinated silicon that are bonded by hydroxyl groups. Kaolinite is represented by the chemical formula Al2Si2O5 (OH)4, and it most often occurs as clay-sized, platelike, hexagonally shaped crystals.

A silicon modulus of enriched bauxite 10.9 units was obtained. As a result of the autoclave leaching of gibbsite-kaolinite bauxite after a two-stage enrichment, the maximum extraction of alumina into solution was 87.4%. The yield of red mud during the processing of bauxite enriched and calcined at 950 C was 37.62%.

Kaolinite, the primary component of kaolin, is a white, soft, and non-plastic clay that acts as an important filler in this polymer field. It produces a smooth surface finish, reduces shrinkage and cracking during curing, improves impact strength, and enhances resistance to the effects of weathering and chemical action for polymers [2] .

The original kaolin ore contains kaolinite minerals as the main components, and there are a small number of impurities such as montmorillonite, quartz, and illite to varying degrees. Therefore, kaolin used as a mineral filler must be beneficiated and purified. The beneficiation process of kaolin depends on the type of ore.
