In the paper, the experimental research on dephosphorization and iron yield for high-phosphorus oolitic hematite by coal-based carbothermal reduction was carried out. It indicated that microwave can speed up the rate of carbothermal reduction of iron ore and strengthen the effects of dephosphorization and increasing iron content. The dephosphorization rate and iron yield of high-phosphorus oolitic hematite exceeding 87.8% and 91.8% by the way of carbothermal reduction in the microwave field and a further fine-grinding and magnetic separation.

In the paper, the research on raising the grade of iron ore and dephosphorization for high-phosphorus oolitic hematite by coal-based carbothermal reduction in microwave field was carried out. The microwave action mechanism was analyzed by the aspects of ionic crystal lattice energy and thermodynamics and dynamics[1]. The possibility of the application of microwave in raising the grade of iron ore and dephosphorization for high-phosphorus hematite was discussed. The research indicated that the primary structure of the high-phosphorus hematite was changed by the high-phosphorus hematite carbothermal reduction in microwave field, meantime the carbothermal reduction reaction activation energy was decreased and the reduction rate was speeded up[2-4].
