that over-reduction has occurred to generate wustite (FeO)
(Wentao, Z., et al., 2022). In addition, the element mass
of point 9, 10, 11, and 12 exceeded 2.35, indicating that
the magnetite was almost converted to wustite (FeO) by
minerals phase transformation. Therefore, this discussion
corresponds to the results obtained in the experiments.
The Mechanism of Minerals Phase Transformation
Based on the results of the above discussions and character-
ization studies, the mechanism of the minerals phase trans-
formation for oolitic hematite was determined by XRD,
VSM, XPS, and SEM-EDS. The schematic of reaction
