kaolin content would contain 39.49% by weight of Al 2 O 3 and therefore, the kaolin quantity in the products was calculated in proportional to the Al 2 O 3 content as a ratio of (100:39.49). Based on the results of the 20-second time samples from the 2-inch and 10 mm hydrocyclones (see Table 5 & Table 6 ), the kaolin grade and recovery ...
