low grade iron ore beneficiation process

Abstract. Low grade iron ore received from the West Singhbhum area of Jharkhand state in India was used to develop a beneficiation flow sheet to remove alumina (Al 2 O 3) and silica (SiO 2) from the ore to get iron (Fe) rich product for steel plants.Mineral characterization showed that the main mineral constituents present in the head sample are goethite, limonite, hematite, quartz, clay and

Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.
Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a high grade concentrate with very low levels of impurities.
