KAOLIN: Drugs of Mineral Origin – Pharmanotes
Kaolin is mined from the surface layer of stones, clay, and sand which are in-depth up to 100 feet. The average thickness of clay varies from 12 to 15 feet. Kaolin is removed by firing a high-pressure water jet at the quarry face. The clay is then sifted and refined to remove impurities before finally being dried to reduce its moisture content.

To discover the origin of these deposits, a mineralogical, geochemical (major and trace element) and stable isotope study (O and H) of kaolinite was carried out. Mineralogically, Blanquita mine is characterized by the presence of dickite, kaolinite, alunite and pyrophyllite, whereas in Equivocada mine, kaolinite is accompanied by dickite and traces of alunite (without pyrophyllite).

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or …
