industrial uses of bentonites

Industrial Applications of Bentonite SpringerLink

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 properties.The main uses of bentonite are in drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides. As of around 1990, almost half of the US production of bentonite was used as drilling mud. Minor uses include filler, sealant, and catalyst in petroleum refining. Calcium bentonite is sometimes marketed as fuller's earth, whose uses overlap with those of other forms of beBentonite

The use as a binder in foundry molds is still considered a major application for which the swelling variety is preferred, although non-swelling bentonite is used for some foundry purposes. Some non-swelling bentonites, depending on their chemistry and molecular structure, can be altered by acid leaching to render them useful as catalysts for Practical Uses of Bentonite in Industries. Bentonite has a high cation exchange capacity, which means it can absorb and retain positively charged ions such as calcium, magnesium, and sodium.

Industrial Applications ScienceDirect

Clays and clay minerals are used in a wide variety of industrial applications (i) because of inertness, stability and unique rheological properties and (ii) because of their reactivity and catalytic activity. In terms of tonnage, four classes of clays are distinguished: common clays, industrial kaolins, bentonites and palygorskite–sepioliteUSES & SPECIFICATIONS Bentonite has high swelling properties along with good viscosity and liquid limit. These properties are highly valued in most of the industrial applications. Sodium bentonite is well suited as a binder in the preparation of pellets and in foundry and as oil-well drilling mud.

Mineralogy, chemistry and physical properties of bentonites

The bentonite deposits in Başören Kütahya, W Anatolia, Turkey were formed by alteration of Pliocene perlite and pyroclastic rocks. Two types of bentonites are distinguished in this area on the basis of their physical properties, chemistry and occurrence. Bentonites were examined to determine their mineralogical, chemical and physical properties.The vast deposits of Nigerian bentonite clay have many significant uses in different aspects of industrial fields of which the oil and gas industry is a potential consumer of this clay mineral.

Industrial Use of Brazilian Bentonite Modified by Mild Acid Attack

For many industrial uses bentonites must be cleared of impurities. In the present paper, a sample of Brazilian bentonite from Vitoria da Conquista, Bahia was modified by mild acid attack using hydrochloric acid under moderate conditions (90 °C, reaction times of 1, 6, 12, 18 and 24 h in close reactor, concentration of the aqueous Bentonite can be used is an intact form for many industrial purposes. However, bentonite must be purified to montmorillonite for use in the food and pharmaceutical industries. As montmorillonite has swelling, rheological, moisture-retaining, and adsorption characteristics, it has been widely studied as an active ingredient in Application of montmorillonite in bentonite as a pharmaceutical

Bentonite, Kaolin and Selected Clay Minerals (EHC 231, 2005)

Sodium bentonites provide good dry strength in moulds, whereas calcium bentonites provide good "green" (condition prior to drying) strength. Bentonite is used in a large number of different cosmetic products, such as paste masks, skin care and cleansing preparations, eyeliners, foundations, and others.Bentonite is a natural mineral mostly composed of hydrous aluminum silicates (their formula being something like Al2H2O12Si4, which means there is a basic content of Aluminum, Hydrogen and Silica). It’s usually negatively charged. Therefore, it attracts cations, like Sodium, Calcium, Iron, and Magnesium.What is Bentonite? Uses and Applications Lonestar
