Article Preview

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].
