| Abstract: | In order to make full use of high-phosphorus iron ore,a 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 dephosphorization rate and iron yield of high-phosphorus oolitic hematite reach 87.8% and 90% by the way of carbothermal reduction in the microwave field and a further fine-grinding and magnetic separation.The mechanism of action of microwave and iron ore was studied from the as... |
