1. Introduction. Kaolin is a white-brown powdery clay mineral. It has the main constituent of kaolinite of a hydrous aluminum silicate (Al 2 O 3.2SiO 2.2H 2 O) with a single tetrahedral silicate layer linked via oxygen molecules to a single alumina octahedral layer. The most common auxiliary minerals found with kaolin are maternal rocks such as …
