Abstract

Method for the bleaching and refining of clays, characterized in that the clay is mixed with an aqueous medium, an alkaline bisulfite is added to the mixture, stirring, in the approximate proportion of 0.350 to 2.802 kg per ton of said clay, add an alkaline borohydride to the resulting mixture in the proportion of 0.063 to 0.500 g. per ton of said clay, maintaining the temperature of the reaction system at approximately 4.14 to 93.33º C, and maintaining the pH value. 2.5 to 5, finally washing the clay to release it from residual bleaching agents and reactable products.
