Abstract: | Detailed mineralogical characterization study has been conducted on low grade iron ore sample from Bellary-Hospet region, Karnataka, India by using XRD, optical microscopy and M�ssbauer spectroscopy techniques for identifying the eminence of iron ore sample. Liberation analysis was carried out by particle size analysis and specific gravity measurement. Chemical analysis results showed that, -125+90? size fraction assaying up to 57.34% Fe, 8.55% SiO 2 and 8.6% Al 2 O 3 . XRD analysis revealed the presence of major hematite phase along with kaolinite, gibbsite, quartz and goethite in the sample. Microscopic study confirms the transformation of magnetite to hematite by martitization. M�ssbauer spectrum reveals the existence of hematite ?-Fe 2 O 3 phase with small distortion in crystal structure. � 2019 Author(s). |
