Quantitative Investigation of Roasting-magnetic Separation
Natural high-quality iron can be directly applied to pyro-metallurgy process, however, the availability of these ores has become less and less due to exploitation. This research reports a systematic approach using reduction roasting and magnetic separation for oolitic iron ores from west Hubei Province. Firstly, a mineralogical study was performed and it was shown that the oolitic particles

The magnetic susceptibility of the hematite (Fe 2 O 3) sample used in this work, measured at 0.95×10 −6 m 3 /kg, is lower than that of the ilmenite sample (2.18×10 −6 m 3 /kg). Hematite contains ferric irons and cannot be oxidized further. In fact, oxidation roasting of hematite did not change its magnetic susceptibility.
