ABSTRACT:
A process is described for activation of layered silicates having an ion exchange capacity (IEC) of at least 25 meq/g by treating them with an acid, characterized in that the layered silicate is activated with about 1 to 10% by weight (based on the dry layered silicate) of an acid at a temperature of not more than 80.degree. C. and the activated layered silicate is calcined at temperatures of about 200.degree. to 400.degree. C. and comminuted desired.
