The washed kaolin is then directed to filter press machines to produce filter cakes. These filter cakes are laid out in the presence of sunlight for drying. Following this drying step, the cakes are broken into smaller pieces and packed into bags for transportation to various industries. ... Mining and processing kaolin. ;10(3):189–193 ...
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 shape, and enhancing certain …
Production advantages are that the process uses conventional equipment and ordinary flotation reagents. Minerals such as calcite, fluorspar, silica, barite, sulphur, etc., are possible carriers.
