Kaolin and Bentonite: Comparing and Contrasting
The extracted bentonite is then processed by wet or dry methods, with wet methods being more common. Wet processing involves adding water to the bentonite powder to form a slurry, followed by purification and drying. Dry processing involves drying the bentonite powder and then milling the dried powder to the desired size.

Hydraulic Performance of Alginate-Based Bentonite
Bentonite clay is widely used as a hydraulic barrier in geosynthetic clay liners and cut-off walls. The interaction of the clay with divalent electrolytic solutions such as Ca 2+ or Mg 2+ deteriorates its sealing properties. The treatment of bentonite with polymers has improved its hydraulic properties; however, sustainability concerns have led to the discovery of an alternate …
