Flotation aid and process for removal of impurities from

I claim: 1. A method for removing impurities from a kaolin clay is contained in a crude mineral mixture along with said impurities, said method comprises subjecting a slurry of said crude mineral mixture to a flotation process in the presence of a sufficient amount of an alkali aluminate compound to improve the removal of said impurities as a floated fraction.

Flotation aid and process for removal of impurities from

During a flotation process the flotation aid is added to a mineral slurry during a pre-conditioning procedure, as described in detail below. To insure maximum effectiveness, the pH of the slurry during the pre-conditioning procedure is preferably maintained at 4.0 or higher, and more preferably above 7.0.
