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.

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.
