  • Utilization of Iron Ore Slimes A Future Prospective

    In India iron ores processing industries play a vital role in the Indian economy. During the washing and processing of iron ores slimes less than 0.15 mm are generated and discarded into the tailing pond. These slimes need processing as they cannot be used directly in blast furnaces. In the present investigation a typical iron ore slime sample containing 59.22 Fe 4.76 SiO2 and 4.57

    HBI is the result of a secondary transformation of iron ore. When iron ore is extracted from the ground it comes in the form of iron oxide. In order to make steel this iron oxide must first be reduced to iron metal so it can be melted. The traditional way to reduce iron oxide to iron is through a blast furnace using coking coal as a reductant.

    Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however because iron does not occur naturally it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
