Sedimentary kaolin clay is frequently contaminated with a small amount of a colored titaniferous impurity which detracts from the brightness and value of the clay. Some of the premium grades of kaolin clay presently available have improved brightness as a result of the removal of a substantial proportion of the titania by selective froth flotation.

Clay minerals of great purity are scarce; such is the case of kaolin. Many methods currently used for its purification damage some characteristics of industrial interest of the clay mineral, and these methods are aggressive to the environment.
