Kaolin mining process

Kaolin was obtained from extracted kaolinite or kaolinite-illitic gritstone or pudding-stone from the “mine U” in southern Moravia using the following procedure (unpublished data): 1. Superficial soil layer (about 50 cm) was removed, and the raw material was floated to a suction pump by water cannon (water source was a pond formed on the surface of the mine after kaolin extraction).

2. It was transported in the form of dense slurry through about 150 m long pipeline with about 20 cm in diameter to the processing plant halls.

3. After kaolin washing, classification and separation steps according to the particle size, kaolin sedimentation, addition of colloid agent, and kaolin drying in wire baskets, the product was finished and could be dispatched to customers.
