iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
The Fe content of the iron ore sample was 31.9%. The X-ray diffraction (XRD) analysis revealed that the ore consisted of hematite (Fe 2 O 3) with density of 5.26, goethite [FeO(OH)] 3.3–4.3, and silicates 2.6–2.8 g/cm3. The overall density of the sample was measured as 3.18 g/cm3. The iron ore sample was screened to −9.5+4.75
