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.

Purification of brazilian kaolin clay by flotation

Jan 01, 2000 A kaolin clay from northern Brazil was beneficiated by flotation using an alkylhydroxamate (R6973) as collector. Unlike tall oil fatty acids, this collector does not require activators (divalent cations) for adsorption. Approximately 90% of the particles in the clay sample were finer than 2 μm; therefore, it was a challenge to remove colored
