2021-8-6 · The chemical composition of the low-grade iron ore in the Sangan iron mine using the XRF analysis showed that the sample contained 52.33% Fe2O3, 14.2% CaO, 13.6% SiO2, and 4.98% Al2O3. Also, the total Fe and FeO content of the sample were determined to be 36.86% and 1.8%, respectively. The Fe/FeO ratio of the sample was 4.55, indicating a magnetite nature for the sample. The sulfur content of the sample was determined to be 0.12%, which was below the standard limit of 0.2%, and therefore, there was no need for desulfurization. The mineralogical composition of the sample was determined using XRD analysis, which showed that the primary ore minerals of the sample were magnetite and hematite, and the main gangue minerals of the sample were calcite and quartz. Also, the sample contained kaolinite, diopside, and dickite as minor gangue minerals. The SEM-EDS analysis showed that the iron minerals were fully liberated in the particle size less than 30 μm.
