Bentonite is a plastic clay generated from the alteration in situ of volcanic ash, consisting predominantly of montmorillonite. Bentonite presents strong colloidal properties and increases its volume several times when coming into contact with water, creating a gelatinous and viscous substance.
Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.

The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated.

Bentonite. Bentonite is the common name for naturally occurring clay that contains the active montmorillonite mineral. The special properties of montmorillonite that enable commercial applications include the sub-micron platelet structure, very high surface area (≈ 800 m 2 /g), and inherent negative charge in the platelet that is counter balanced by exchangeable cations.
Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite.One of the first findings of bentonite was in the Cretaceous Benton Shale near Rock River, Wyoming.The Fort Benton Group, along with others in stratigraphic succession, was named after Fort Benton, Montana in the mid-19th century by Fielding Bradford Meek and F. V. Hayden ...
The production process of Bentonite essentially involves the following operations. The crude clay is mixed with water to form a suspension to which sulfuric acid is added. The mixture is then heated by steam in a mixing tank up to a temperature of 40oc and kept at this temperature for about 4 hours.
Bentonite Slurry in civil engineering. Bentonite slurry is a combination of sodium bentonite and slurry. A slurry is a thin sloppy mud or cement or, in extended use, any fluid mixture of a pulverized solid with water, often used as a convenient way of handling solids in bulk. This combination is frequently utilized to form a solid protective barrier in the ground.

Back to Rocks and Minerals Articles Kathy Feick "The clay with 1000 uses" Bentonite was first named Taylorite, after William Taylor, who studied clay deposits in the United States. The use of the name Taylorite stopped when this group of minerals was split up into separate groupings. In 1898, W C Knight used the name bentonite to refer to this specific type of clay because the
Supergroove™ technology is a groove in the nonwoven fabric that allows the bentonite to migrate out and self-seam at the overlap. This feature eases the installation process by eliminating the need for supplemental bentonite and the additional labor to apply it. Lamination capabilities to provide composite geomembrane-GCL products.
Bentonite Processing Technology. 1.Sodium Modification Stage:Most of bentonite in the nature is calcium bentonite whose performance is worse than sodium bentonite. 2.Drying Stage: After sodium modification, the bentonite has high moisture and must be dried to reduce the water content by dryer. 3.Grinding Stage:After drying, the bentonite would be crushed into the little particles meeting the ...

Bentonite Processing Simultaneous drying and grinding. Bentonite is a natural absorbent aluminium phyllosilicate clay in the Montmorillonite family that is formed by the decomposition of wind-borne volcanic ash. Due to the physical nature of this material, a Raymond® roller mill produces the best results at the usual fineness of grind.
Ronald S. Jackson PhD, in Wine Science (Third Edition), 2008. BENTONITE. Bentonite is a type of montmorillonite clay widely employed as a fining agent. It is used in clarifying juice and wines, in removing heat-unstable proteins, and in limiting the development of copper casse. Depending on the objectives, the ability of bentonite to induce partial decolorization and remove nutrients, such as ...
