还原剂及脱磷剂对高磷鲕状赤铁矿直接还原-磁选影响的研究进展OACSTPCD

This is an article in the field of mining engineering.The effects of reducing agent and dephosphorization agent on the direct reduction of high phosphorus oolitic hematite were reviewed.The research status of the influence of reducing agents on the reduction of high-phosphorus oolitic hematite was summarized from two aspects of coal and other reducing agents,and the research progress of dephosphorizers was summarized from two ways of using single and combined dephosphorizers.The problems existing in the direct reduction-magnetic separation process of high-phosphorus oolitic hematite were pointed out.According to the existing problems,suggestions for the future research direction of direct reduction-magnetic separation of high-phosphorus oolitic hematite were put forward.
