XRF analysis was carried out to confirm the changes in the chemical composition of the bentonite clay due to acid treatment as described in Section 2.3.The results are presented in Table 2.The raw bentonite sample predominantly contained silica (SiO 2), alumina (Al 2 O 3) and iron oxide (Fe 2 O 3).In addition, some impurities in the …
The beneficiation of bentonite clay was carried out by crushing to particle size <74 m using a mortar, pestle and sieve, and followed using gravity separation, purified using distilled water and ...
The mineral characterization of bentonite clay deposits in Nigeria in its raw form have indicated that the clays are mainly calcium-based montmorillonite and this differs significantly from the industry standard which is a sodium based montmorillonite clay. Beneficiation or activation of these clays with a sodium salt has been largely used by ...
The calcium bentonite clay in the raw gypsum ore has a particle size of ~1-5 µm, whereas the gypsum and quartz have a particle size of ~1-2 mm. Therefore, the calcium bentonite clay can be separated through sieving. Sieving is cost-effective; however it is not the most effective beneficiation process as some impurities remain after sieving.
