转炉钢渣中磷资源回收利用的研究进展

Research progress on the recycling of phosphorus resource from converter steelmaking slag

综述了火法及湿法处理钢渣两个角度磷资源回收利用的研究现状,深入分析了各方法的优缺点及限制性环节。在此基础上,对未来的发展进行了展望,并提出了火法处理转炉钢渣时应选用以吸热反应为基础的还原剂及廉价固废改质剂,湿法处理转炉钢渣应选择无机酸与有机酸相结合溶出磷的未来发展思路。

The research status of phosphorus recovery and utilization from pyrometallurgical and wet processes was reviewed,and the advantages and disadvantages of each method were analyzed.On this basis,the future development was prospected,and the development thought which the reducing agent based on the endothermic reaction and the cheap solid waste modifier should be selected.In addition,the dissolution of phosphorus by combining of organic acid and inorganic acid was also suggested.
