Beneficiation of Indian High Alumina Iron Ore Fines a Case

The iron ore fines sample was collected from the spiral classifier overflow of a typical Iron ore beneficiation plant of Noamundi, India. The sample was dried, thoroughly mixed and analysis indicated that the dried sample contained 59.77% of total iron, 5.89% alumina and 4.71% silica with an LOI (Loss on Ignition) of 5.53%.

Study on the Induration Cycle During Pelletization of

Indian blast furnaces are fed with lump iron ore (10 - 40 mm) and sinter as burden. Sinter is a prepared burden, where iron ore fines of size -10 + 0.15 mm are agglomerated using mainly flux and coke. Iron ore fines of less than 0.15 mm are not utilized in sintering technology and hence are mostly discarded at mines during processing as slime.
