Development of process for beneficiation of low-grade iron ...

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 ...
