Process Flow Of Water-washed Kaolin Production. Kaolin is a non-metallic mineral, a kind of clay and clay rock dominated by kaolinite clay minerals. Because it is white and delicate, it is also called Baiyun Earth, and it is named after Gaoling Village, Jingde Town, Jiangxi Province. The pure kaolin is white, fine, soft, and soft.

Wet Processing. The second process used to produce kaolins is much more complex and is called the wet process. The kaolin is dispersed in water after it is mined. The first step after dispersion is the removal of the coarse grit ( > 44 µ) by settling procedures and vibrating screens.

Kaolin is an aluminosilicate soft white mineral named after the hill in China (Kao-ling) from which it was mined for centuries. In its natural state kaolin is a white, soft powder consisting principally of the mineral kaolinite, and varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase.

Kaolin is used in many consumer products and as a functional additive and process enabler in manufacturing. It is typically extracted from open-pit mines that range from small to very large scale (tens to hundreds of thousands of dry metric tons produced per year). Ore processing consists of removing impurities, engineering particle size and ...
