The first step in processing kaolin clay is to slurry it in a blunger with water and a dispersing agent. Degritting using screens, cyclones and hydroclassifiers is the next step. The minus 325 mesh degritted clay is fractionated using centrifugal sizers to produce the fine fractions demanded by the various markets.

The first fraction is then beneficiated (such as by flotation, selection flocculation, high intensity magnetic separation and/or leaching) to produce a kaolin clay product with improved optical properties. The first and second fractions may be combined to produce a product with improved optical properties.
WhatsApp The beneficiation process involved washing of the clay, sieving, drying and subjecting each sample to gravity separation other beneficiation method used included screening of the kaolin samples at 120mesh size and froth floatation, this method was employed in reducing the silica content, so as to improve on the alumina level.

Abstract: A beneficiated kaolin clay slurry is concentrated from a solids content of about 50% to 60% by weight to a solids content of at least 65% by weight by evaporating water therefrom by passing the aqueous clay slurry through one or more noncontact evaporated heat exchangers. The kaolin clay slurry is passed in indirect heat exchange relationship with a heating vapor, with the heating ...
