Abstract In order to realize the efficient recycling of converter phosphorus containing steel slag, the production status,composition,source,and migration and enrichment mechanism of phosphorus,mineralogical structure,and research status of dephosphorization technology of converter slag are systematically analyzed. On this basis,through the discussion and summary the recycling technology of converter phosphorus-containing steel slag,it shows that the current steel slag recycling technology has the disadvantages of low phosphorus resource utilization efficiency and large energy consumption of steel slag. Therefore,it is an inevitable trend to determine the utilization mode according to the phosphorus content of steel slag and reduce the energy loss of steel slag as much as possible in the recycling process. Based on the previous research,the prospect of efficient recycling of low phosphorus slag and high phosphorus slag is further prospected,so as to provide theoretical basis and technical reference for iron and steel enterprises to improve the recycling rate of converter phosphorus-containing steel slag and reduce the production cost of raw materials.

Key words： converter slag containing phosphorus recycling dephosphorization of steel slag phosphorus resources
