Effect of Impurities on the Rheology of Two Kaolins

Two kaolins were given five successive processing steps designed to remove a number of impurities: (1) removal of nonclay and soluble fractions; (2) removal of organic material; (3) removal of iron oxides; (4) removal of allophane; and (5) removal of three- layer lattice minerals. After each of these steps, consistency curves were obtained for each of the
