摘　　要：通过热力学分析磷与钒分离的可能性,并进行了分离的实验研究。结果表明:碳热还原含钒钢渣后还原渣中磷的含量在0.2%以下,还原率达到95%以上;钒的损失率在13%左右,并在还原渣中呈现富集现象。还原后XRD图谱表明渣中高价铁氧化物与磷氧化物被还原,还有少量的FeO存在。The possibility of separation of phosphorus and vanadium was analyzed by thermodynamics, and the experimental study of separation was carried out.The results show that the content of phosphorus in the reduced slag is below 0.2% and the reduction rate reaches over 95% after the carbothermal reduction of vanadium containing steel slag.The loss rate of vanadium is about 13%,and enrichment occurs in the reducing slag.After reduction,the XRD spectra showed that the iron oxides and phosphorus oxides in the slag were reduced and a small amount of FeO existed.
