Kaolinite Processing | Equipment, Process Flow, Cases
The kaolinite dry mining process is a simple and economical process. The ore is crushed to 25.4mm by a hammer crusher and fed into the cage mill to reduce the particle size to 6.35mm. The hot air in the cage mill reduces the moisture of the kaolin from about 20% to 10%.

Process for beneficiating kaolin clays
A improved process for beneficiating kaolin clays to remove discoloring impurities is disclosed. The beneficiation of kaolin clay is improved by fractionating a kaolin clay starting material into a lower brightness first fraction having a majority of the discoloring impurities and a higher brightness second fraction with less impurities.

Kaolin Flotation: Beyond the Classical
cess used with kaolin on a large scale at Engelhard Corporation and was put into commer- cial operation in 1961 (Greene et al., 1961). In this process the conditioning of kaolin is accomplished with two essential agents, tall oil and calcium carbonate, which coopera- tively permit improved beneficiation of the very finely divided feed.
