     · The low grade iron ore contains about 38.9% iron as hematite 55.7% Fe 2 O 3 and the rest is mostly quartz SiO 2 with traces of alumina Al 2 O 3. This type of ore, when subjected to beneficiation, typically yields a tailing containing SiO 2, and 0.44% Al 2 O 3. The iron ore tailing is considered as a waste and its disposal poses a major environmental concern.
