Bentonite is one of the most versatile and widely used industrial minerals. Known for its swelling, binding, and absorbent properties, it plays a crucial role in various industries including oil and gas drilling, foundries, construction, agriculture, cosmetics, and environmental engineering.
India, with rich bentonite reserves, is a major producer and exporter of this valuable mineral. Companies like HTMC Group have emerged as leading bentonite manufacturers, bentonite suppliers, and bentonite distributors, offering high-quality products across domestic and global markets.
What is Bentonite?
Bentonite is a naturally occurring clay composed primarily of montmorillonite. It is classified into two main types:
-
Sodium Bentonite – High swelling capacity, excellent water absorption, and thixotropic properties.
-
Calcium Bentonite – Lower swelling but better stability and used in specific industrial applications.
Due to its unique structure and high surface area, bentonite is used in both raw and processed forms. It is available as powder, granules, or lumps depending on the industry’s needs.
Key Applications of Bentonite
1. Drilling Industry
Bentonite is widely used in drilling fluids for oil, gas, and water wells. It acts as a lubricant and cooling agent, stabilizes boreholes, and removes cuttings from the drill bit.
2. Foundry
In metal casting, bentonite is used as a binder for molding sands. It enhances mold strength and thermal stability.
3. Iron Ore Pelletization
Sodium bentonite binds iron ore fines into pellets, making them suitable for use in steel manufacturing.
4. Construction & Civil Engineering
Bentonite is used in tunneling, diaphragm walls, waterproofing, and slurry trenching due to its sealing and thixotropic properties.
5. Agriculture
Bentonite improves soil quality by increasing water retention. It is also used as a carrier for fertilizers and pesticides.
6. Cosmetics & Personal Care
In skincare, it acts as an absorbent and detoxifying agent in face masks, soaps, and creams.
7. Environmental Protection
Bentonite is used in landfill liners, hazardous waste containment, and water purification because of its impermeability and ion exchange capabilities.
