Separation and purification of montmorillonite and ...

2010-7-1  Its presence in both raw and purified samples indicated that the applied granulometric treatments (even the method 3) were inappropriate for the separation of kaolinite from montmorillonite. Spectra of the raw bentonites presented two bands at 780 and 802 cm − 1 (Fig. 7 (a) and (c)), which were characteristic of quartz (Bosch-Reig et al., 2002).
