Bentonite-organic material reactions, however, are also used where the clay acts to deeolorize oils and to coagulate sediment in such liquids as beers and wines.Certain industrial jobs are performed best by particular bentonites in regard to type and quality and attempts are made to match the bentonite with a particular application. The two most common natural forms of bentonite are sodium ...

Industrial Applications of Bentonite | SpringerLink

01/02/1961· Bentonites react chemically with many organic materials to form compounds which are used chiefly as gelling agents in a variety of organic liquids. Bentonites are selected for each industrial need on the basis of type and quality. This selection is based principally on physical properties, and chemistry of the bentonite becomes involved only to the extent that it influences the physical ...

Bentonite - Wikipedia

For industrial purposes, two main classes of bentonite are recognized: sodium and calcium bentonite. Sodium bentonite is the more valuable but calcium bentonite is more common. [6] In stratigraphy and tephrochronology , completely devitrified (weathered volcanic glass) ash-fall beds are commonly referred to as K-bentonites when the dominant clay species is illite .

What is Bentonite? - Industrial Minerals Association ...

Depending on the nature of their genesis, bentonites contain a variety of accessory minerals in addition to montmorillonite. These minerals may include quartz, feldspar, calcite and gypsum. The presence of these minerals can impact the industrial value of a deposit, reducing or increasing its value depending on the application. Bentonite presents strong colloidal properties and its volume ...

21/10/2012· INDUSTRIAL USES Clay-Water Mixtures Bentonite-water mixtures are used for bonding, plasticizing, and suspend-ing. This versatility is made possible chiefly by adjusting the quantities of thetwo components. A bonding agent must have certain adhesive properties, and these aredeveloped when bentonite is mixed with only a small amount of water.When oriented water is shared by adjacent clay …

Bentonite - an overview | ScienceDirect Topics

Bentonite has a wide variety of uses including foundry, animal feed, drilling mud, absorbent, industrial, and specialty uses. About 70% of the world's known supply of Western or sodium-type bentonite occurs in the state of Wyoming (notably in the Mowry Formation), with additional significant deposits elsewhere in the Western United States. Volcanoes of the Yellowstone area of Wyoming were ...

industrial uses of bentonites - menuiseriefreson.be

Bentonites, which consist essentially of clay minerals of the smectite group, have a wide range of industrial uses. A particular feature of this group of minerals is the substitution of Si4+ and Al3+ in the crystal structure by lower valency cations. This leaves unsatisfied negative

Four types of industrial clay raw materials are examined in this contribution, kaolins, bentonites, fibrous clays (palygorskite and sepiolite) and common clays and shales. The latter are used in ...

bentonite industrial applications

Bentonite quality and consequently its applications depend on whether it contains any of these other minerals Bentonite is an industrial mineral rich in a clay mineral called montmorillonite Bentonites used for hydraulic barriers in North America are produced from the naturally occurring sodium bentonites mined in the state of Wyoming...

INDUSTRIAL APPLICATIONS OF BENTONITE by

Most industrial applications involve the swelling property of bentonite to form viscous water suspensions. Depending upon the relative proportions of clay and water, these mixtures are used as bonding, plasticizing, and suspending agents. Bentonites disperse into colloidal particles and, accordingly, provide large surface areas per unit weight of clay. This large surface area is a major reason ...

For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite. In stratigraphy and tephrochronology, completely devitrified (weathered volcanic glass) ash-fall beds are commonly referred to as K-bentonites when the dominant clay species is illite. Other common clay species, and sometimes dominant, are montmorillonite and kaolinite. Kaolinite-dominated clays are ...
