Learn About Bentonite


Bentonite Uses;

Foundry: Bentonite is used as a bonding material in the preparation of molding 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.

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.

Pelletizing: 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 used traditionally as a thixotropic, support and lubricant agent in diaphragm 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 wastewater purification. Common environmental directives recommend low permeability soils, which naturally should ontain bentonite, as a sealing material in the construction and rehabilitation of landfills to ensure the protection of groundwater from the pollutants. Bentonite is the active protective layer of geosynthetic 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 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 pelletizing aid in the production of animal feed pellets, as well as a flowability 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.

Pharmaceuticals: Cosmetics and Medical Markets: 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 an antidote in heavy metal poisoning. Personal care products such as mud packs, sunburn paint, baby and facepowders, and face creams may all contain bentonite.

Detergents: Laundry detergents and liquid 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 Polishes: 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 are appreciated for the finishing of indigo dying cloth, and in dyes (lacquers for paints & wallpapers).

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 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.orillon, in Southern France.


Re-think Industrial Minerals Extraction!

The advantages of modern society could not be possible without industrial minerals.  Many of the luxuries we all value depend on this important class of natural resources.  You may not be aware of the many benefits industrial minerals provide.  In many ways, the low-profile of our industry is a testament to our ability to operate using clean and responsible extraction methods.  But we are behind the scenes, making your life easier, everyday.
Beneficial Beauty
Consider the beauty around you in the modern world.  Look at the room you are sitting in while you read this page.  Is there paint on the walls?  Industrial minerals are there.  Are there ceramic vases or tableware near by?  Industrial minerals are there.  Can you see through a glass window?  Industrial minerals are there?  Or consider the benefit of personal beauty products or the fresh smell of clean clothes made possible through detergents.  Industrial minerals are there, too.
Beneficial Comfort
Is it cold out-side and warm inside?  Modern insulation would not be possible without industrial minerals.  Do roof shingles protect your home in a storm?  Industrial minerals give shingles their strength.  Do you enjoy comfort foods?  Again, fertilizers and soil additives are made possible by industrial minerals.
Beneficial Surroundings
What would our world look like without glass?  What would the lives of our pets be like without products such as cat litter?  How would we thrive without bricks, mortar, drywall and concrete?  Our surroundings, in large part, are made from industrial minerals.
Beneficial Hobbies
It is quite likely that your hobbies and passions are made possible by industrial minerals.  Do you like to work with wood?  Guess what the grit on sandpaper is.  Do you collect porcelain or ceramic figurines?  Guess what is in both substances.  Do you enjoy writing in a journal?  Guess what is in the ink.  If you guessed industrial minerals to all of the above, you are right.
Beneficial Recreation
What do you do for fun?  Industrial minerals join you in many sports and recreational activities.  From golf balls to fishing rods, chances are your favorite hobby relies on industrial minerals.  Tennis rackets, skis, and back packs, all contain industrial minerals.  Have fun!
Beneficial Refreshment
Do you enjoy a glass of wine or a cold beer?  Industrial minerals are used to filter out insolubles in these adult beverages.  Next time you make a toast, remember the industrial minerals that make the drink taste better.
Beneficial Reading
The quality of paper, books and magazines is greatly improved by industrial mineral additives.  The shine on high quality paper, for instance, owes its shimmer to industrial minerals.
