A small amount of metallic iron (Fe m) was also present in both roast experiments at 1000 °C. The formation of the other Fe 2+-bearing phases with different magnetic susceptibilities will affect subsequent beneficiation. Hence, 1000 °C is considered too high a roasting temperature for the gas atmospheres employed in this study.

mining technology: beneficiation of IRON ORE

Though the hardness value of quartz (i.e. 7 on the Mohr's scale) is a bit higher than the iron ore (Hematite (5.5-6.5), Magnetite (5.5-6), it is far more brittle than iron ore (Gribble, 1988). The disparity in the cumulative weight% retained and cumulative passing of the ore is demonstrated by Figures 1 and 2.
