Kaolin Kaolin, soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, and many other products Kaolin is named after the hill in China Kao-ling from which it was mined …
The mineralogy and texture of the kaolin ore and its beneficiated product determine its potential use (Fig. 7). Refractories, fiberglass and ceramics are fit-for-use based on their chemistry. Refractories need to have low amounts of alkali's and iron. The kaolin-bearing ores used for refractory applications range from nearly pure kaolin ...
Chemical beneficiation methods involve the removal of mineral impurities from kaolin clay by organic and inorganic acids such as oxalic acid [ 9 – 15 ], citric acid [ …
