The bentonite concentrates after alkaline activation are suitable for drilling muds while the products of acid activation can be used as bleaching clay. Cost–benefit analysis of the suggested flowsheet, of beneficiation and activation, proved the economic viability of such processes. Utilization of these clays, after their upgrading and ...

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 ...

Bentonite is classified as Na-bentonite (surface area is almost 20–30 m2/g) and Ca-bentonite (surface area is 60–120 m2/g) [33], which were used to remove oil from water, and the potential of bentonite clay for oily water treatment was discovered [34–37]. Aluminosilicate is a major component of zeolite with a tectosilicate structure [32].
