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 (Al2O3) and silica (SiO2) 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. The ...

Benefication steps include crushing, concentration, flotation, and/or roasting. The blast furnace is the dominant type of equipment for the production of iron metal. Part of the heat needed for the production of iron is used to heat up the raw materials to be processed and part of it is required for endothermic chemical reactions.
