hematite was weakened and disappeared, while the diffrac-
tion peaks corresponded to magnetite, indicating that the
iron minerals were converted from hematite to magnetite
(Kamariah, N.,et al., 2022). And the diffraction peaks of
gangue were identified as quartz. Figure 7(b) indicated that
when the reduction time increased to 40 min, the diffrac-
tion peaks of magnetite gradually increased. As the reduc-
tion time further increased from 40 min to 90 min, the
diffraction peak of hematite almost disappeared.
