In this contribution, the mineralogical and chemical characterization of Bajrawia iron ore is investigated. The chemical analysis was conducted using atomic absorption spectroscopy, X-ray Fluorescence, Energy Dispersive X-ray and titration. The mineralogical characterization was obtained by optical microscopy and X-ray diffraction. The physical properties such as densities, water content and porosity were determined. It was found that Bajrawia iron ore contains about 35.5% Fe and some impurities like phosphorus and silica. Goethite is the major iron mineral associated with minor contents of hematite, kaolinite and quartz. SEM photo showed that the main minerals are goethite, clay minerals and quartz. The ore has low density because it has high porosity degree. This type of iron ore is disseminated in rock matrix and would be difficult to process.
