replacing cementitious material by red mud (RM) and in the same mix partially replacing sand by iron ore tailings. Cementitious material in the mixture was replaced with red mud at 1%, 2%, 3% and 4%. For each red mud replacement level, 10%, 20%, 30%, 40% of fine aggregate (regular sand) was replaced with Iron Ore Tailings. European Scientific Journal July 2014 edition vol.10, No.21 ISSN: 1857

Reductive Smelting of Red Mud for Iron Recovery

conducted experiments of red mud smelting with pig iron recovery in an electric arc furnace. The composition of the gained pig iron is shown in Tab.2. The use of red mud as a substitute or in addition to iron ore is not realized yet due to the high alkaline content of the slag which causes serious problems with the refractory of installed blast

Red Mud an overview ScienceDirect Topics

Red mud is composed of minerals such as hematite, gibbsite, calcite, quartz, goethite, diaspore, rutile, kaolinite, etc. (Wang and Liu, 2012) measured by using X-ray diffractometer.The specific gravity of red mud is 2.77 gcm −3 measured by gas picnometer. According to its particle size distribution, it is very fine material and has a high surface area (Wang and Liu, 2012).
