making much of the kaolin unusable for commercial applications due to insufficient whiteness. That is why the mined kaolins need to be beneficiated by removal of undesirable minerals - mica constituents and other iron-bearing minerals before they could be considered as a suitable raw material for some of the above-mentioned purposes.
Biological beneficiation of kaolin: A review on iron removal.
Abstract-The removal of titanium minerals from kaolin can be accomplished by treatment with stability, and the titanium mineral particles, primarily anatase, are liberated and can be separated by sedimentation. Substantial removal ofanatase impurities can be achieved by usually heavily stained by iron and as a result.

Kaolin iron removal method and kaolin iron removal process. In the process of selecting kaolin, the raw ore is first made into clay, which decomposes the minerals in the water in the form of granules of micron size or even smaller.
The Removal Of Mineral Impurities From Kaolin Using … THE EFFECT OF DISCOLORING IMPURITIES The brightness and color of the pigment are influenced to a degree by relatively small quantities of (1) discrete, colored impurities present in the kaolin and (2) iron hydroxide stains on the surface of the particles.
Historically, iron has been removed by chemical leaching, changing the form of the iron, and "washing" it from the kaolin.
It is necessary to oxidize the ferrous iron in the kaolin with a strong oxidant by an oxidation-reduction combination method. The ferric iron is reduced, and the ferric iron is reduced to divalent iron by a reducing agent, followed by removal with the filtrate.
