of magnetite ores using low-intensity magnetic separation. Although magnetite stoichiometrically contains the highest iron (72.4 wt %) compared with all the other sources of iron, its low-grade ore state usually contains low iron—magnetite ores located in Australia usually contain iron grades between 14 and 45 wt % [4–6]

Development of process for beneficiation of low-grade iron

Feb 01, 2018 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 gibbsite
