Abstract: Iron ore collected from Muro, Nasarawa State, Nigeria was analysed with the aid of an X-ray fluorescence spectrometer (XRF), X-ray diffractometer (XRD), scanning electron microscope (SEM-EDS) and petrographic microscope. The XRF results revealed total iron content (FeT) of 30.86-35.21% and SiO2 is 48.7-51.1%. The XRD results showed that the ore majorly contained quartz (54%) and goethite (44%). The SEM photomicrograph revealed greyish portions which are the iron-bearing minerals and dark portions which are the silica. The EDS analysis revealed the predominant elements in the ore as iron (Fe) and silicon (Si) with a composition of 52.60% and 34.95%, respectively. The petrographic investigation revealed that the dark opaque minerals found on the photomicrographs are iron oxides and the major associated gangue mineral is quartz. Muro iron ore may be another potential source of raw material for the iron and steel industries.
