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.
