What is Kaolin?

The word “kaolin” derives from Mandarin word “KAOLING”, which means “high mountains”. Kaolin mining has been conducted from several centuries ago. Kaolin is a mass of stones, consists of clay mineral with low iron composition. Kaolin is composed of aluminium silicate hydrous (Al2O3 2SiO2 2H2O) plus some side minerals (nacrite, dicrite, haloisite). The formation process of kaolin is caused by decay of materials that occur on the surface or near the surface, and hydrothermal alteration process (occurs near cracks or places with high permeability) in frozen rocks, which contain feldspar – where potassium and aluminium silicate minerals are transformed into kaolin. It can also be formed by decay of metamorphic rocks, especially gneiss, while secondary kaolin is a result of primary kaolin transportation. In Indonesia, potential kaolin sediments are residual sediments from the decay of acidic rocks or granite.
