Kaolin Oxidation Bleaching Method: Leaching is carried out in the presence of a weakly acidic solution (pH 3 to 4) with a reducing agent (NaS2O4) to keep the dissolved iron in the Fe2+ state, avoiding the formation of Fe(OH)3, and washing it with water to make it Kaolin separation. In order to remove the dark organic matter, it can be bleached with a strong oxidizing agent (hydrogen peroxide, sodium hypochlorite, etc.), and the Suzhou Kaolin Company has obtained high-quality kaolin products by oxidative bleaching. It has been reported that treatment of kaolin with microorganisms can significantly improve the quality of the product.
