The processing of kaolin involves several steps to extract and refine the mineral for its desired applications. Mining: Kaolin deposits are typically found near the earth's surface and extracted through open-pit or underground mining. The ore is removed using heavy machinery, such as bulldozers, draglines, or power shovels.

The kaolin is mined with diesel or electric shovels or draglines and loaded in trucks for transport to the processing plant or dropped directly from the dragline into a blunger. The blunger chews the kaolin into small lumps and mixes it with water and dispersing chemical to form a clay-water slip or slurry.
