    To remove a colored titania impurity from kaolin clay, the impure clay is formed into a well-deflocculated aqueous slip. A small amount of a soluble source of polyvalent cations, e.g., calcium chloride, is dissolved in the slip. An anionic organic polyelectrolyte is added and the slip is agitated until titaniarich flocs form and settle out from the deflocculated slip.

    Flocculation

    Flocculation, in the field of chemistry, is a process in which colloids come out of suspension in the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from precipitation in that, prior to flocculation, colloids are merely suspended in a liquid and not actually dissolved in a solution
