Bentonite clay is one of the oldest clays that humankind has been using from ancient times as traditional habits and remedies. In recent years researchers have found many applications of bentonite clay due to its various physio-chemical properties. In the present work, various physical and chemical properties of bentonite such as surface area, …

According to estimates from the Nigerian Mining Corporation and the Raw Materials Research Development Council (RMRDC), deposits of local bentonite clays in Nigeria has been modestly projected to be above 700 million metric tons (Aigbedion and Iyayi, 2007a, Aigbedion and Iyayi, 2007b, Raw Materials Research and Development …

Foundry: Bentonite is used as a bonding material in the preparation of moulding sand for the production of iron, steel and non-ferrous casting. The unique properties of bentonite …

Pillared bentonites were prepared by a simple intercalation method with iron oxide and iso-propoxide titanium to improve its adsorption of organic matter (OM) contained in industrial phosphoric acid 54 % P2O5. The solid structure of raw and modified bentonite were analyzed using X-ray diffraction and transmission electronic microscopy. The …

In this paper, the main modification methods of bentonite, the preparation methods of bentonite composite materials, and the application of bentonite composite …

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.

preparation of moulding 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. Pelletising: Bentonite is used as a binding agent in the production of iron ore pellets.

Bentonite used for drilling operations in the oil and gas industry in Nigeria is mainly imported into the country. This project evaluated the efficiency of additives and their function in enhancing the rheological and flow properties of local bentonite clay, obtained from Ibule-soro in Ondo State, Nigeria. X-Ray diffraction analysis of clay samples from …

Abstract and Figures. As an important industrial material, bentonite has been widely applied in water-based drilling fluids to create mud cakes to protect boreholes. However, the common mud cake ...

This chapter discusses the properties and uses of bentonite. Bentonites have a variety of uses in various industries. The properties of bentonites are contingent upon …

These findings indicate the potential industrial applications of modified bentonite in a contaminant barrier system. Modified bentonites for the anti-seepage system have been attracting global attention. At the same time, the performances of modified bentonite containing ... (2011) Preparation and characterization of zwitterionic surfactant ...

Calcium bentonite, known as fuller's earth in Great Britain (Robertson, 1986), is acid activated to make bleaching earths used as a refining and clarifying agent in the production of edible oils and fats, and industrial oils and waxes. Acid activation enhances properties already present in the clay by changing certain chemical and physical ...

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.

for the cooking oil industry, basic chemicals, and non-metallic minerals which in 1993 consumed about 90.4% of total bentonite consumption of 20,498 tons. The oil purification industry is the largest consumer of bentonite as a CPO pallor material, estimated at about 200,000 tonnes of bentonite is required by the oil purification …

However, these materials form colloidal suspensions in water or in aqueous solutions, which makes their separation and recovery difficult and prevents their implementation on an industrial scale. To overcome these limitations, in the present work, a silica-resin-bentonite composite material was synthesized and activated with HNO3.
