Naturally occurring bentonite clay: Structural augmentation
Bentonite sample post beneficiation was treated with sulfuric acid followed by calcination. The structural augmentation of the acid-treated bentonite was examined by characterization techniques comprising of XRF, FTIR, XRD, DTA, SEM and BET. Detailed characterization revealed substantial removal of metal oxides along with structural water ...

BENEFICIATION AND CHARACTERISATION OF A BENTONITE FROM …
The XRD confirmed the presence of montmorillonite meaning the sample contained bentonite, while the XRF confirmed that the sample is Ca-based rather than the standard Nabased, hence the need for beneficiation. Beneficiation of the bentonite was done by ion exchange with Na2CO3 followed by addition with different compositions of viscosifiers ...
