The highest magnetic susceptibility was obtained when the peak intensity ratio between hematite and ilmenite was between 1.5 and 3.5. 4. Reduction roasting of the ilmenite using charcoal as a reducing agent at 800 °C increased its magnetic susceptibility significantly, and the magnitude of the increase was higher than oxidation roasting.
