Reaction Behavior of Iron Minerals and Metallic Iron

The reaction behavior of iron minerals and growth of metallic iron particles in coal-based reduction of an oolitic iron ore were investigated by X-ray diffraction (XRD) and scanning electron microscopy/enegry dispersive spectroscoy (SEM/EDS), respectively. The results show that, the reduction of iron minerals occurred in the sequence of Fe2O3 → Fe3O4 → FeO → Fe.
