Experiment Study on the High-Phosphorus Hematite Carbothermal Reduction in Microwave Field

Abstract:

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.
