Abundant Resources: Nigeria has enormous resources, most of which are yet to be fully exploited. They include mineral, agricultural and human resources. Large Market: Nigeria offers the market in sub-Saharan Africa, with a population of about 120 million people. The Nigerian market potential also stretches into the growing West African sub-region.
Organoclays consist of bentonite that is modified with quaternary amines. Bentonite is a volcanic rock whose main constituent is the clay mineral montmorillonite. This gives the bentonite an ion exchange capacity of 70-90 meq/gram.

Na-bentonite type is the one used in drilling fluids, because it has good dispersion stability, high swelling capacity, and outstanding rheological properties. Ca-bentonite generally has bad rheological performance; however, it can be activated by sodium to be used in drilling fluids, since there are huge unutilized Ca-bentonite resources.
Mineral resources are materials of economic interest found in or on the earth's crust in such quality, quantity and form that can be considered for economic extraction. In Nigeria, mineral resources play a great role in the economic sector. In fact, the Nigerian economic is skewed toward the exploration of minerals specifically petroleum. This makes […]
Clays and Clay Minerals. First and foremost, it is essential to define what clay is and how it differs from mud, soil, and minerals. In the field of geology clay is a size-based term for very fine-grained minerals with an estimated spherical diameter <2.0 µm and approximate density of 2.65 g/cm 3 as defined by Stokes Law (Jackson, 1979; Moore et al., 1997).
Calcium Bentonite Clay is reported to contain no less than 57 minerals. This impressive assortment of minerals includes calcium, iron, magnesium, potassium, manganese, and silica as well as trace elements, those appearing in very tiny amounts. The mineral content being extremely high sets the stage for replenishing dietary deficiencies.
discovered in several towns in Nigeria. Modest estimate of the bentonite clay reserves in Nigeria by Aigbedion and Iyayi (2007) place the reserve at 166.9 million metric tons. For just this reason and due to the vast resources employed in the importation of foreign bentonite, the Federal Government placed an embargo on the importation

"Will has vast and in-depth knowledge of a range of clay mineral materials, and I have hired him on various occasions to analyse the expected performance of bentonite clay in GCLs. He has always produced reports of outstanding quality, and provided support when needed.
Organoclays consist of bentonite that is modified with quaternary amines. Bentonite is a volcanic rock whose main constituent is the clay mineral montmorillonite. This gives the bentonite an ion exchange capacity of 70-90 meq/gram. By exchanging the nitrogen end of a quaternary amine onto the surface of the clay platelets, by cation exchange ...
The addition of clay minerals in drilling fluids modifies the dispersion's viscosity. In this article, scientific advances related to the use of clays and clay minerals (bentonite, palygorskite, sepiolite and mixtures of clay minerals) in drilling fluids are summarized and discussed based on their specific structure, rheological properties, applications, prevailing challenges and future ...

919 N. Salahudeen et al. / Nigerian Research Journal of Engineering and Environmental Sciences 5(2) 2020 pp. 918-928 Bentonite is a clay mineral belonging to the montmorillonite mineral family.
The mining industry in Nigeria is regulated by the The Nigerian Minerals and Mining Act of 2007,National Minerals and Metals Policy 2008 and Nigerian Minerals and Mining Regulations 2011. About 34 minerals deposits have been identified in Nigeria and one of such is Bentonite.

1. SUMMARY 1.1 Identity, physical and chemical properties, and analytical methods . Bentonite is a rock formed of highly colloidal and plastic clays composed mainly of montmorillonite, a clay mineral of the smectite group, and is produced by in situ devitrification of volcanic ash. In addition to montmorillonite, bentonite may contain feldspar, cristobalite, and crystalline quartz.

Equilibrium data obtained from the multi-metal ion system were fitted to Langmuir, Freundlich, two-site Langmuir and Langmuir–Freundlich equilibrium adsorption models, while kinetic data were fitted to pseudo-first-order (PFOM), pseudo-second-order (PSOM), Elovich, double
The Bentonite and the Barite is actually a natural resource in Nigeria. 700 million tonnes of this mineral resource is spread in some states like Adamawa, Borno, and Plateau while over 7.5million tonnes of barite have been discovered in Taraba and Bauchi state. There you have it, List of Mineral Resources in Nigeria and Their Location.
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. In this review article, the key miner-alogical
Bentonite clay is predominantly light colored and expands when mixed with water. Bentonite are made up of predominantly the montmorillonite mineral, which is a subset of the smectites group. The general expression for montmorillonite mineral present in bentonite clays is m (Mg[Si 4 O 10] × [OH] 2) × p([Al, Fe] 2 × [Si 4 O 10]) m:p = 0.8–0 ...
Bentonite (/ ˈ b ɛ n. t ə ˌ n aɪ t /) is an absorbent swelling clay consisting mostly of montmorillonite.It usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. Bentonite beds are white or pale blue or green in fresh exposures, turning to a cream color and then yellow, red, or brown as the exposure is weathered ...
