Characterization and purification of Algerian natural bentonite …
After beneficiation by NaCl, the volume percentage of the fine particle size increased dramatically compared to the raw sample, and two maxima (one centered at 0.3 μm and the other centered at 1.5 μm) were attributed to the purity of the purified bentonite clay, hence this small particle size suggests the application of purified clays in ...
