Geochemical And Geological Characterisation Of Kaolinite Deposits Around Kaoje, Kebbi State, Nigeria

摘要

Abstract: Kaolin deposits in Kaoje have been analysed for their geochemical and geological (physical) characteristics in evaluating their quality for utilisation in local Industries. Physical (grain size) analysis show a moderate proportion of clay and silt size particles for the samples obtained (K1= 47.0 wt. %, K2= 41.8 wt. %, and K3= 50.2 wt. % respectively). Chemical data show that the Kaolin is composed mainly of SiO2 and Al2O3. Other oxides being present in various amounts include K2O, Fe2O3, and CuO. Also, Ca, Cr, Zr, As, and Ni occur in trace amounts and their depletion shows the extent of Kaolinisation. The physical and chemical characteristics of the Kaoje kaolinite indicate that they are suitable for industrial use.
