초록

A method of treating a kaolin particulate material to improve its properties by removal of impurities which includes the steps of: (a) producing a dispersed aqueous suspension of a kaolin particulate material containing at least 0.1% by weight, based on the dry weight of the kaolin particulate material, of separable impurity by adding a dispersing agent to the kaolin particulate material to deflocculate solid particles of the material in the suspension; (b) conditioning the suspension prior to adding selective flocculation polymer thereto by allowing...
