Research Progress on the Effects of Reducing Agents and Dephosphorization Agents on Direct Reduction-Magnetic Separation of High Phosphorus Oolitic Hematite

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.
