Historical Background hide. Kaolin, or "china clay", is the name for rocks that are rich in Kaolinite (a layered silicate clay mineral). It is a soft, earthy, usually white mineral, produced by the chemical weathering of aluminum silicate minerals like feldspar. In many parts of the world, it is colored pink-orange-red by iron oxide, giving it ...

Exploring the Properties and Applications of Kaolin
The ore is removed using heavy machinery, such as bulldozers, draglines, or power shovels. Blunging: The mined kaolin ore is then transported to a processing plant, which is crushed and mixed with water to form a slurry. This process is called blunging, which helps to disperse the particles and produce a homogenous mixture.
