Construction and Civil Engineering :Bentonite in civil engineering applications is used traditionally as a thixotropic, support and lubricant agent indiaphragm walls and foundations, in tunnelling, in horizontal directional drilling and pipe jacking. Bentonite, due to its viscosity and plasticity, also is used in Portland cement and mortars.

Environmental Markets : Bentonite's adsorption / absorption properties are very useful for waste water purification. Common environmental directives recommend low permeability soils, which naturally should contain bentonite, as a sealing material in the construction and rehabilitation of land fills to ensure the protection of groundwater from the pollutants.Bentonite is the active protective layer of geo synthetic clay liners.

Drilling : Another conventional use of bentonite is as a mud constituent for oil and water well drilling. Its roles are mainly to seal the borehole walls, to remove drill cuttings and to lubricate the cutting head.

Oils / Food Markets : Bentonite is utilized in the removal of impurities in oils where its adsorptive properties are crucial in the processing of edible oils and fats(Soya / palm / canola oil). In drinks such as beer, wine and mineralwater, and in products like sugar or honey, bentonite is used as aclarification agent.

Agriculture : Bentonite is used as an animal feed supplement, as a pelletizing aid in the production of animal feed pellets, as well as a flow ability aid for unconsolidated feed ingredients such as soy meal. It also is used as an ion exchanger for improvement and conditioning of the soil. When thermally treated, it can be used as a porous ceramic carrier for various herbicides and pesticides.

Detergents : Laundry detergents and liquid hand cleansers / soaps rely on the inclusion of bentonite, in order to remove the impurities in solvents and tosoften the fabrics.

Pharmaceuticals and Cosmetics : Bentonite is used as filler in pharmaceuticals, and due to its absorption / adsorption functions,it allows paste formation. Such applications include industrial protective creams, calamine lotion, wet compresses, and antiirritants for eczema. In medicine, bentonite is used as antidotein heavy metal poisoning. Personal care products such as mud packs,sunburn paint, baby and face powders, and face creams may all contain bentonite.
