“…It consists of the main mineral referred to as kaolinite. The kaolin is composed of abundantly 1:1 clay mineral Al2Si2O5(OH)4 structure per alumina-silicate producing bulky congested particles of SiO4 tetrahedral sheets and AlO2(OH)4 octahedral sheets [5]. The AlOHOSi hydrogen bonds is attached to each two unbroken layers since the kaolinite layer is neutral.…”

Abstract. The mineral and elemental composition, crystal structure and particle size distribution of kaolin clays have been determined to ascertain its industrial significance. The mineral composition is evaluated by X-Ray Fluorescence (XRF), crystalline structure by X-Ray Diffraction (XRD) and particle size distribution using low angle laser light scattering (LALLS) technique. The results shows the presence of eight elements expressed in percentages in form of their oxides as: SiO 2, Al 2 O 3, Fe 2 O 3, MgO, CaO, K 2 O, TiO 2 and P 2 O 5. Five crystalline structures are revealed by XRD result. The particle size distribution shows that kaolin particles are mainly in the range of 25-35 µm, while few particles have size distribution varied between 0.4-0.75 μm. The report is found to be in agreement with other researchers.

“…The surface properties of clay determines their industrial application [6]. Numerous techniques have been proposed to enhance the surface properties of clay materials, comprising intercalation [7], chemical activation [8] mechanochemical activation [9,10] and thermo-chemical treatment [11]. Equally as the chemical activation technique has been established, acid treatment is an effective method to develop the functioning of clay minerals [3].…”

Raw kaolin was refluxed by sulphuric acid in variable concentrations of 2 M, 4 M, 6 M and 8 M. The morphology and elemental compositions of the acid-leached kaolin were analyse by Field Scanning Electron Microscopy (FESEM) and Energy Dispersive X-ray analysis (EDX) respectively. The disintegration and leaching of Al 3+ ions of the clay are determined by FESEM studies. The acid treatment increases the silicon content and decreases aluminium content as revealed by EDX analysis. The leaching of Al 3+ ions increases with gradual increase in concentration of the acid. Therefore, kaolin reflux with acid at lower strength (2 M and 4 M) are more dispersed and more industrially useful than that which is treated at higher acid strength.

“…The sample was placed in an oven running at a temperature of 80 o C for 30 minutes. The kaolin was finally washed with distilled water, filtered with the aid of filter paper, and dried in an oven operating at a temperature of 100 o C. The leaching process was adopted from Jikan et al [19].…”

Zeolites being used as builders in detergents are synthesized from expensive chemicals with a cumbersome production process. In this study, zeolite was synthesized from cheaper and readily available kaolin for possible use in detergent production. Kaolin from two sources namely Ajebo, Ogun State and Darazo, Bauchi State, Nigeria was used as starting materials while wet beneficiation followed by acid leaching was used to purify the kaolin and hydrothermal process was used to synthesize the zeolite. The chemical analysis confirms the presence of silica and alumina which are the precursors materials for zeolite synthesis. An increase in the amounts of the desired silica and alumina for both kaolin accompanied by a reduction in the amounts of the undesired oxides present in the kaolin as impurities are clear indications that the acid leaching was successful. The zeolites synthesized from both kaolin shows better water adsorption capacity and ion exchange capacity compared to those reported for zeolite synthesized from pure chemicals, this ability makes zeolite more suitable for the production of detergent. These results are indications that zeolites synthesized from kaolin can serve as a possible replacement for the more expensive zeolite synthesized from chemicals used as builders in detergent production.
