ABSTRACT
This study considered the mineralogical, elemental composition in form oxides and engineering properties such as particle size, specific gravity, bulk density; water content and atterberg limits of two kaolin deposits in Kpankorogi in Edu Local Government of Kwara State and in Ijero-Ekiti in Ijero-Ekiti Local Government Area, Ekiti State.This is with a view to assessing their potentials for Various industrial applications. The analyses includes X-Ray Diffraction (XRD and X-Ray Fluorescence(XRF). It was observed that the kaolin sample from Kpankorogi is dominated by Quartz and the one from Ijero- ekiti by Orthoclase. The result of the chemical analysis indicates the presences of SiO2, Al2O3, Fe2O3, TiO2, MnO, CaO, MgO, K2O, Na2O, CuO, ZmO, Cr2O5, V2O5 and Sc2O3. The X RD In particular, shows that Kpankorogi kaolin contains Quartz and Kaolinite while Ijero- Ekiti contains in addition to kaolinite,s orthoclase and Muscovite. Considering the possible applications of the two kaolin deposits, it was observed they do not meet the required standards completely in all instances.
