Chemical and mineralogical characterization of lateritic iron ore deposit at Auchi, Edo state, Nigeria

Abstract

The laterite iron ore deposit at Auchi, Edo State, Nigeria was studied chemically and mineralogically. The results of the chemical assay are moisture (0.02 - 1.11%), L. O. I. (2.31 – 2.93%), Fe2O3 (50.40 – 66.29%), Al2O3 (17.25 – 25.50%), CaO (0.32 - 0.36%), MgO (2.60 – 2.96%) and SiO2 (5.22 – 26.00%). The mineralogical studies showed the presence of goethite, diaspore, rutile and kaolinite respectively.
