flocculation to remove iron from kaolin PURIFICATION OF KAOLIN BY SELECTIVE FLOCCULATION. Key words: kaolin, selective flocculation, kaolin purification, stone industry, kaolin Sodium hydrosulphite has been used for soluble iron removal during the.
A process which uses selective flocculation with hydroxamates for the beneficiation of mixtures of mineral particles (such as kaolin clays). The increased selectivity of hydroxamates for certain mineral phases within kaolin clays and other mixtures of mineral particles improves the process over selective flocculation processes utilizing other activators.
To remove a colored titania impurity from kaolin clay, the impure clay is formed into a welldeflocculated aqueous slip. A small amount of a soluble source of polyvalent cations,, 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.

The effect of pH and polymer type on efficiency and mass recovery of the selective flocculation were studied. In the pH range studied (from 7 to 11) the polymer SFA150 with high anionic charge (50%), was shown to be inefficient in removing the TiO 2 present in the kaolin. The titanous impurities were significantly removed by the use of polymers with weak anionic charges (10%) in alkaline medium.
