Beneficiation and applications of an Egyptian bentonite

Previous studies on some Egyptian bentonites (such as Qasr El-Sagha, Kom-Osheim, Maadi, Aun-Musa, etc.) suggested that, without beneficiation, they were unsuitable for most industrial applications (drilling mud, foundry, refining and bleaching, etc.). Response of these bentonitic clays to Na-exchange was poor and their hydration, plastic bentonite, clay formed by the alteration of minute glass particles derived from volcanic ash. It was named for Fort Benton, Mont., near which it was discovered.. The formation of bentonite involves the alteration of volcanic glass to clay minerals; this requires hydration (taking up or combination with water) and a loss of alkalies, bases, and possibly silica, Bentonite Volcanic ash, Healing, Detoxification Britannica

Additionally some bentonites can contain the silica mineral cristobalite. In addition to quartz and cristobalite, some bentonites particularly 'white bentonites' can contain large amounts of opal, which may occur in a variety of paracrystalline forms.Bentonites Clays and Minerals

Characterization of Philippine natural bentonite

Philippine natural bentonite is characterized using X-ray diffractometer (XRD), scanning electron microscope (SEM), chemical analysis, thermogravimetric-differential scanning calorimetry (TG-DSC), and Fourier transform infrared (FTIR) analysis. The cation exchange capacity (CEC) was also measured. XRD shows that the mineral is 1 Introduction. Bentonite is a geological term for soil materials with a high content of a swelling mineral, which usually is montmorillonite. It is produced by in situ devitrifications of volcanic ash [].Although, bentonite chemical composition varies from one place to another place [].The bentonite clay is often extracted from open pit mines with Wiley Online Library Separation and characterisation of

Potentialization of bentonite properties as support in acid catalysts

Bentonites belong to the family of smectites that, historically, have been used as acid catalysts [ [6], [7], [8]]. Their structure is laminar type 2:1 or TOT by the order of the layers in a sheet: tetrahedral-octahedral-tetrahedral [8]. The acidity of these materials is associated with the presence of small amounts of substitutions of Al 3The proven reserve of bentonite in Nigeria has been modestly estimated to be above 700 million metric tons (Aigbedion and Iyayi, 2007a, Aigbedion and Iyayi, 2007b, James et al., 2008, Omole et al., 2013, Bilal et al., 2015) with the bulk of it lying in Afuze, Edo State, Mid-Western Nigeria which holds about 70–80 million metric tons of Properties and application of Nigerian bentonite clay deposits for
