Bentonite Info
What is Bentonite?
Bentonite is highly absorbent clay consisting of Montmorillonite mineral. It is one of the most effective natural intestinal detoxifying agents available. It has the ability to swell more than Five times than its normal volume when placed in water.
Bentonite History & General information
Bentonite is a material compounded of clay minerals predominantly Monterillonite. Bentonite swells considerably when mixed in water, thus makes it preferably for protecting formations from invasions by drilling fluids. Bentonite is form when volcanic ash is marine basins are altered.
Bentonite Properties
There are generally two types of Bentonite. One is called the Swelling Type or Sodium Bentonite, which has single water layer particles containing Sodium ( Na+ ) as the exchangeable ion.
The other one is called the Non- Swelling or Calcium Bentonite, which has double layer particles with Calcium (Ca++) as the exchangeable ion.
Bentonite is formed by the alteration of volcanic ash deposits, mostly in upper cretaceous formations. In the early years , all the naturally occurring activated clays hving good bleaching properties were called fuller’s earths. The word fuller’s earth has been named after the practice of fulling or cleaning the grease and stains from wool and cloth. The major difference and important difference between Bentonite & Fuller’s earth is with their respective modes of occurrence and with other physical properties.
Fuller’s earth is a representation of shaly facie Tertiary Rock and on the other hand Bentonite is formed by the alteration of volcanic ash deposits, that also mostly in upper cretaceous formations.
Bentonite can absorb water to a greater extent than ordinary plastic clays. Where as the Fuller’s earth, on the other hand is Non-Plastic in character. The absorption of water in sodium bentonite proceeds with a considerable increase in volume ( upto 14times to its original volume) creating an excellent gel and viscous material which is invaluable for the preparation of drilling muds and in the grouting of dams, wells etc…..
Sodium Bentonite has an excellent Thixotropic property, i.e the gel becoming stiff on standing and reverting to fluidity when shaken. The swelling type bentonite when dispersed in water, separates into suspendible flakes which are all finer than 0.5 micron. Calcium bentonite yields about 35% finer than 0.5 micron. Calcium bentonite yields about 35% finer than 0.5 microns. The difference in bentonite and other clays lies in lattice structure. The sheet of atoms in bentonite are much thinner and more easily separable in water. That is why bentonite occupies more surface area than other clays. This property is known as dispersibility, which is unique to swelling type of bentonite.
Bentonite Drilling Fluids
A clay mineral that is composed principally of three-layer clays, such as montmorillonite, and widely used as a mud additive for viscosity and filtration control. Commercial bentonite ores vary widely in amount and quality of the swelling clay, sodium montmorillonite. Ores of lower quality, those with more calcium-type montmorillonite, are treated during grinding by adding one or more of the following: sodium carbonate, long-chain synthetic polymers, carboxymethylcellulose (CMC), starch or polyphosphates.
These help make the final product meet quality specifications. Unfortunately, the additives may not remain effective in "the real mud world" when in use at the rig due to hardness ions in the water, high temperature, bacterial attack, mechanical shear-degradation and other factors that can render these additives ineffective.
Bentonite Cure
Natural clay, especially the form known as bentonite, has not only been used medicinally for centuries by indigenous peoples around the world, but has, in recent years, been increasingly prescribed by practitioners of alternative medicine as a simple but effective internal cleanser to assist in reversing numerous health problems. Bentonite is not a mineral but a commercial name for montmorillonite, the active mineral in many medicinal clays and which comes from weathered volcanic ash.
A VOLCANIC DETOXIFIER—Bentonite, a medicinal powdered clay which is also known as montmorillonite, derives from deposits of weathered volcanic ash. It is one of the most effective natural intestinal detoxifying agents available and has been recognized as such for centuries by native peoples around the world. Whatever the name, liquid clay contains minerals that, once inside the gastrointestinal tract, are able to absorb toxins and deliver mineral nutrients to an impressive degree, says Knishinsky. Liquid clay is inert which means it passes through the body undigested.

Bentonite Usage
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.
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. Drilling muds consists of water which sodium bentonite and pulverized barytes are added. Such muds are prepared mainly for Oil well drilling it gives the fluids a viscosity several times that of water and Thixotrophy. It seals the wall of the holes , thus preventing water loss.
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.
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.
Foundary Sands
Bentonite is utilized in foundry to bind the sand grains into desired shapes. Bentonite helps in retaining the mechanical shape of the mould by making the particles of sands adhere and also making the surface impermeable. Strength and fusion point are the two important properties desired for selecting bentonite. Generally, the swelling type of bentonite is used though other types of bentonites have also been used.
Use in Cosmetic and Pharmaceutical Preparations
Bentonite gels are used as a carrier for a number of cosmetic preparatios, tooth-pastes, creams for skin and other similar products. For the preparation of cosmetic creams, bentonite is generally used as a paste formed with water and glycerine. Bentonite when intimately mixed with water in the proportion of one to four gives a pasty mass with the consistency of a heavy grease and in this form it is used for the preparation of medicinal ointments. Bentonite in the natural state is non-poisonous and harmless; thus it finds use in tooth-paste and even in the preparation of lipstick.

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.
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.
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).
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.
