Method for leaching of iron from kaolin — The raw

1988-1-1  A new method for leaching of iron from kaolin, conformed with the material composition of the iron compounds in the Bulgarian kaolins, is developed. A strong reducing agent is used in the method: sodium dithionite, prepared in kaolin suspension at the interaction of the initial reactants-sodium bisulphite and granulated zinc.
