Fig. 53 shows a typical flow sheet for dry processing kaolin. In the dry process, the properties of the kaolin product are almost entirely dependent on the crude clay quality as delivered from the mine. For this reason, deposits must be selected that have the brightness, grit percentage, and. Halloysite mining and processing

Kaolin is a form of clay. Clays are formed by the weathering of rocks. Weathering of rocks can be classified as physical or chemical process. In case of kaolin, the chemical reaction between water, carbon dioxide and feldspar (rock) gives rise to kaolin clay deposits. Feldspar (Rock) + Water + Carbon Dioxide (Gas) -> Kaolin (Clay)
