Known for its good absorption capacity, Bentonite is a type of aluminium phyllosilicate with features similar to impure clay. Most of its content comprises of Montmorillonite. In 1898, Wilbur C. Knight named absorbent clay as Bentonite after the name of Cretaceous Benton Shale near Rock River,Wyoming in America. Set up in 1963, the Gujarat Mineral Development Corporation Limited (GMDC) is the prime lignite and minerals mining company across in India. This state regulated organization is possessed by Government of Gujarat.
We are a major name in the market of Bentonite, worldwide. Our company has an extensive stock of high-quality Sodium and Calcium Bentonite. These are thoroughly mined & processed into several grades. Also, they are available in different forms such as dried / crushed lumps, granules and powder etc. to meet the diverse needs of clients. Our Bentonite Products are used in a range of industries including: Construction, Paper, Detergents, Drilling, Iron Ore Pelletisation, Metal Casting, Pet Litter, and more. First discovered in Fort Benton, America, Bentonite is an extremely colloidal clay mineral. There are multiple properties of bentonite, such as: hydration, water absorption, viscosity, swelling and thixotropy, making it a versatile product for various industries.
Mainly two varieties of bentonite are available: Sodium Bentonite (high swelling, gelling & thermal durability) and Calcium Bentonite (less swelling, commonly available world-wide).
Based in Kutch (Gujarat, India), we have a large stock of both Sodium & Calcium based Bentonite. We keep up with high quality, high montmorrilonite based Sodium grades for different industry sectors. Over the years, we have developed several processing facilities with considerable capacity additions on mechanical activation, granulation and grinding etc. Presently, we have a grinding capacity of over 250,000 Mts to cater to the increasing needs in India as well as abroad. Further, we have fully equipped laboratories and state-of- art R&D facility, for quality control and improvement in our processes as well as products. We work with the aim to provide consistent, improved & new products to our customers.
Bentonite – the clay with a 1000 uses.
A highly versatile mineral, Bentonite caters to a broad range of industries, and has a wide variety of applications:
1. Application in Palletising
Used as a binding agent in the manufacture of iron ore pellets. It has higher natural percentage of iron, ideal for isolating iron ore pellets with supreme iron percentage. It is a very economical & efficient binding agent, and widely acknowledged for Pelletization of iron or teconite ores.
Fine free flow powder, 80% finer than the 200 mesh.
Excellent water update & retention that creates effective bond between particles.
Comprises low silica, hence no extra slag formation.
Good water absorption, and thus easy formation of pellets.
Granules grow up fast as they roll.
Maintained binding strength before / after drying of pellets.
Retained pallet shape even on rough handling.
2. Application in Construction & Civil Engineering
Bentonite has been traditionally used in civil engineering applications: as a support, thixotropic & lubricant agent in diaphragm foundations & walls; in tunnelling, horizontal directional drilling & pipe jacking. With its viscosity & plasticity, it is also utilized in Portland cement & mortars. It is acknowledged by civil construction industries for stabilization of the slopes during excavation in unsteady grounds, and for land fill applications.
3. Applications in Drilling
Bentonite has been used as a mud constituent for oil & water well drilling. It seals the borehole walls to withdraw drill cuttings, and is good for cutting head lubricating. Special higher mud results in less use of Bentonite, for the same standardized mud. This helps in lesser requirement of Bentonite. It is widely applicable in oil/water well drilling applications, in strata and saline soil.
When encounter with brine and high temperature in heavy drilling, the Bentonite retains thixotopic properties. It is also recognized for natural gas drilling and oil well applications, under high temperatures & pressures. With its stable gelling characteristics, it is ideal for petroleum industry.
5. Application in Food, Oil & Liquor Industry
Bentonite is used in the removal of oils' impurities where its adsorptive properties are important in the processing of edible oils & fats (palm / soya / canola oil). It is utilized as a clarification agent in drinks such as alcoholic beverage, mineral water, and in products like honey and sugar. Also, it is accepted widely for the clarification purpose in fruit juices etc.
6. Application in Agriculture Industry
Bentonite is used as an animal feed supplement, as a pelletising support in the manufacture of animal feed pellets, and as a flow-ability assistance for unconsolidated feed ingredients. Also, it is used as an ion exchanger for the improvement / conditioning of soil. It can be utilized as a porous ceramic carrier for several pesticides & herbicides, when thermally treated. With high porosity and natural distance between the layers, the Bentonite is a perfect material for the agriculture industry.
7. Application in Pesticide Industry
Pesticides' granule formulation is a very easy & safe way of Pesticides application. During the application, Granules are less capable to drift as compared with spray & dusting. They can be used even in the condition of wind. The granular formulation of pesticides is effective in the control of harmful insects / weeds during the growth of crop. It slowly releases active ingredients over a long period of time. During the formulation, it does not club to the Granulator wall as it is extremely absorbent.
8. Application in Animal Feed
Bentonite is widely used by veterinarians as nutrient in animal and cattle feed.
9. Application in Fertilizer Industry
An eco-friendly carrier of fertilizers, Bentonite is accepted by NPK and DAP fertilizer manufacturers. It is effective for the enhancement of microbial activities as well as improving the fertility of soils.
10. Application in Pharmaceuticals & Cosmetics
With its absorption/adsorption functions, the Bentonite is utilized as a filler in pharmaceuticals & cosmetics. Its applications cover industrial protective creams, wet compresses, calamine lotion and anti-irritants for eczema. In medicine, it is utilized as an antidote in deep metal poisoning. Personal care products such as: sunburn paint, mud packs, face creams, baby & face powders.
11. Application in Detergents
Bentonite is used in the production of laundry detergents, liquid hand cleansers, and soaps etc. It helps remove the impurities in solvents as well as soften the fabrics.
12. Application in Paints, Dyes & Polish
With its good thixotropic properties, the bentonite functions as a thickening / suspension agent and used in paints & varnishes. Its adsorption properties are also good for the finishing of indigo dying cloth & dyes.
13. Application in Cleaning Cat Litter
Bentonite has an advantage with its ability to absorb / refuse by forming clumps, when used for cat litter.
14. Application in Paper Making
Bentonite is essential for paper making, where it is utilized in pitch control, to improve the conversion efficiency of pulp into paper, and to improve the paper quality. Also, it offers useful de-inking properties for recycling of paper. Acid activated bentonite is the active element in the manufacture of carbon less copy paper.
15. Application in Ceramics Industry
Bentonite helps in stabilizing fine, technical & heavy ceramic products. It is used as anti-settling agent in glazes & engobes, as plasticizer, and as fluxing agent.
16. Application as a Catalyst
The chemically adapted clay catalysts find use in a broad range of works, where acid catalysis is an important process. Particularly, they are used in the alkylation activities to produce fuel additives.
17. Application as Electrical Earthing
Bentonite is used for improving ground conductance in the electrical earthing. Low resistance electrocon natural sodium bentonite is ideal for electrical earthing of rocky ground pit.
18. Application in Water Proofing
Bentonite has superior filtration loss properties, making it perfect for water proofing applications. Also helps in environment protection.
19. Application in Foundries
Bentonite offers green sand moulds with good flow ability, thermal stability & compact ability for the manufacture of high-quality castings.
Apart from the above cited industries, the Bentonite also find use in some other areas.
