Beneficiation of natural kaolin is an advanced process to improve kaolin's whiteness and refine it from chemical and physical impurities such as metallic oxides and salts. Furthermore, beneficiation also removes dead mineral phases such as quartz, feldspar, pebbles, gris, muscovite, mica, titanium oxide, and iron oxide.

Dry beneficiation: This method separates kaolin ore with low water content. Dry beneficiation usually includes coarse crushing, magnetic separation, gravity separation and other steps to remove impurities in ore and improve the selectivity of ore. Adding water during the dry beneficiation process is unnecessary, which can save water resources.
