Foundry: Bentonite is used as a bonding material in the preparation of moulding sand for the production of iron, steel and non-ferrous casting. The unique properties of bentonite yield green sand moulds with good flowability,compactability and thermal stability for the production of high quality castings.

Pelletising: Bentonite is used as a binding agent in the production of iron ore pellets. Through this process, iron ore fines are converted into spherical pellets, suitable as
feed material in blast furnaces for pig iron production, or in the production of direct reduction iron (DRI).

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

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

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

Agriculture : Bentonite  is  used  as  an  animal  feed supplement, as a pelletising aid in the production of the animal feed pellets, as well as a flowability aid for unconsolidated feed ingredients such as soy meal. It is also 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.

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

Detergents : L a u n d ry  detergents  and  l iquid  hand cleansers/soaps rely on the inclusion of bentonite, in order to remove the impurities in solvents and to soften the fabrics.

Paints,  Dyes  and  Po l i s h e s : Due  to  its  thixotropic properties, bentonite and organoclays function as a thickening and/or suspension agent in varnishes, and in water and solvent paints. Its adsorption properties, is appreciated for the finishing of indigo dying cloth, and in dyes (lacquers for paints & wallpapers).

Cat Litter: Bentonite is used for cat litter due to its advantage  of  absorbing  refuse  by  forming  clumps (which can be easily removed) leaving the remaining product intact for further use.

Paper: Bentonite is crucial to paper making, where it  is used in pitch control, i.e. absorption of wood resins that tend to obstruct the machines and to improve the efficiency of the conversion of pulp into paper as well as to improve the quality of the paper. Bentonite also  offers useful de-inking properties for paper recycling.  In addition, acid activated bentonite is used as the  active component in the manufacture of carbonless copy paper.

Catalyst: Chemically  modified  clay  catalysts  find application in a diverse range of duties where acid catalysis is a key mechanism. Most particularly they are employed in the alkylation processes to produce fuel additives.
