Evaluation of Physical and Chemical Characterization of Kazaure Iron Ore: Implications for Metallurgical Processing and Beneficiation Techniques.

Abstract

This study presents the physical and chemical characterization of Kazaure iron ore, located in Jigawa State, Northwestern Nigeria, to assess its industrial potential and beneficiation prospects. The ore was subjected to several characterization techniques, including specific gravity and bulk density determination, chemical analysis via X-ray Fluorescence (XRF), and calculation of the Concentration Criterion (CC) for gravity concentration. The results revealed a significant iron content of 41.78%Fe₂O₃, indicating that it is a medium-grade ore suitable for metallurgical applications. The mineral composition identified includes gangue minerals like silica and alumina, which may affect beneficiation efficiency. The CC value of 4.17, which is greater than 2, suggests that gravity concentration is an effective method for separating iron from gangue minerals like silica. Based on these findings, the study recommends the application of magnetic separation, gravity concentration, and froth flotation to enhance the ore's quality. The research highlights the potential of Kazaure iron ore to contribute to Nigeria’s steel production, reduce reliance on imported raw materials, and support industrial growth.
