Abstract (en)
[origin: WO2006120011A1] A process is disclosed for preparing fast-dissolving bentonite granulates, as well as a bentonite granulate prepared by this process. To prepare the bentonite granulate, an overactivated bentonite overactivated with at least 110 % of its cation exchange capacity with alkali metal ions is preferably used as starting material, and is preferably granulated with a water glass solution having a SiO<SUB>2</SUB>:X<SUB>2</SUB>O modulus of more than 3.2, X being selected from sodium and potassium.
