Investigations were carried out, on a low grade siliceous iron ore sample by magnetic separation, to establish its amenability for physical beneficiation. Mineralogical studies revealed that the sample consists of magnetite, hematite and goethite as major opaque oxide minerals where as silicates as well as carbonates form the gangue …

ABSTRACT Mineral and morphological characteristics of chromite ore strongly affect the separation efficiency while upgrading the low-grade deposits. Usually, chromite ore enrichment is carried out by using gravity separation due to high-concentration criterion between chromite and other minerals. However, chromite ore …

The investigations carried out on the low grade iron ore sample reveal the following conclusions. (1) The sample on average contains 43.8% Fe, 16.8% SiO 2 and 5.61% Al 2 O 3. (2) The mineralogical studies indicate that the major iron minerals are magnetite, hematite and goethite. And the gangue minerals are silicates and calcites.
