Bentonite mineral powder is widely used in drilling fluids, foundry moulding, iron ore pelletising, civil engineering, pond and landfill lining, waterproofing, agriculture, cat litter, paints, coatings, and industrial sealing. Its swelling, binding, absorption, and sealing properties make it valuable across construction, mining, manufacturing, and environmental applications.
Bentonite clay powder is used in drilling fluids to help carry drill cuttings to the surface, support borehole stability, and control fluid loss. The grade is selected according to the drilling method and ground conditions.
Bentonite acts as a binding agent in foundry sand to help moulds retain their shape during metal casting. It is widely used in foundries producing metal components and castings.
Bentonite powder is used as a binder in iron ore pellet production, helping fine ore particles form strong, uniform pellets. The required grade depends on the pelletising process and quality specifications.
Bentonite is used in diaphragm walls, slurry trenching, and selected foundation and excavation projects to help stabilise soil and control water seepage. Its performance depends on the soil conditions and project design.
Suitable bentonite grades are used in engineered barriers and lining systems to reduce water seepage. The material must be selected and installed according to the site conditions and environmental requirements.
Bentonite is used in certain waterproofing membranes, joint-sealing products, and construction systems because it can swell when exposed to water. The application requires a compatible grade and suitable installation method.
Selected bentonite products are used in agriculture as soil conditioners and in certain animal-feed applications. Only grades specifically approved for the intended use should be selected.
Bentonite, particularly suitable swelling grades, is used in clumping cat litter and other absorbent products. Its moisture absorption and clumping properties help simplify waste collection.
Certain bentonite grades are used as thickeners, suspending agents, and rheology modifiers in paints, coatings, and other formulations. The appropriate grade depends on the required viscosity and application.
Bentonite is used in selected industrial sealing and drilling applications where swelling and fluid-control properties are beneficial. Grade selection depends on chemical compatibility and operating conditions.

Bentonite powder (also called bentonite clay powder or bentonite mineral powder) is an absorbent clay made mainly of montmorillonite. It forms when volcanic ash, or silica-rich rocks such as granite and basalt, alter in the presence of water. Depending on where it formed, a deposit can also contain minor minerals such as kaolin, mica, illite, quartz, feldspar, calcite, and gypsum powder, and these affect its value.
When bentonite meets water, it swells and forms a gel, which gives it its three key properties:
| Type | Behaviour | Best for |
| Sodium bentonite | High swelling, forms thick gels, very low permeability | Drilling mud, iron ore pelletising, sealants, foundry, waterproofing |
| Calcium bentonite | Low swelling, good adsorption | Soil, bleaching, animal feed binder, cat litter, some foundry use |
| Sodium-activated (soda ash treated) bentonite | Calcium bentonite treated to behave like sodium bentonite | Cost-effective swelling grades |
| Acid-activated bentonite (bleaching earth) | Treated with acid to boost adsorption | Edible oil bleaching |
| Feature | Sodium bentonite | Calcium bentonite |
| Swelling | High | Low |
| Gel strength | High | Lower |
| Typical use | Drilling, sealing, pelletising, waterproofing | Feed, cat litter, soil, bleaching, some foundries |
| Permeability when wet | Very low | Higher |
| Cost | Higher | Lower |
Choose sodium bentonite when you need swelling, sealing or strong binding, and calcium bentonite when absorption and low cost matter more.
The bentonite powder price in India starts from approximately ₹2 per kg, with an indicative price range of ₹2 to ₹5 per kg. The actual price depends on the type of bentonite mineral powder (sodium, calcium, or activated), grade, fineness, moisture content, packaging options (25 kg bags, 50 kg bags, or jumbo bags), order quantity, delivery location, and freight charges.

Bentonite powder is used in drilling mud, foundry sand, iron ore pelletising, waterproofing, landfill and pond lining, civil engineering, agriculture, animal feed, cat litter, ceramics and paints.
It is a clay made mostly of montmorillonite, formed from volcanic ash or silica-rich rocks altered in the presence of water.
It starts from ₹2 per kg, with an indicative range of ₹2–5 per kg depending on type, grade and quantity.
Sodium bentonite swells strongly and forms thick gels, so it is used for drilling, sealing and pelletising. Calcium bentonite swells much less and is used for feed, litter, soil and bleaching.
Yes. When wet it swells into a low-permeability gel that blocks water, so it is used to seal basements, foundations, landfills and ponds.
