Abstract
A method for brightening a kaolin clay wherein an aqueous dispersion is initially formed of said clay, which dispersion is blunged and conditioned and the resultant slurry thereupon subjected to a froth flotation treatment to remove titaniferous impurities. The purified product from the froth flotation treatment is thereupon subjected to magnetic separation by passing such product through a slurry-pervious ferromagnetic matrix positioned in a high intensity magnetic field, which results in substantial, additional brightening of the clay.
