Abstract: Vanadium-bearing steel slag,generated from the steelmaking process of vanadium-titanium magnetite,can be used as the raw material for preparation of V₂O₅.However,it is still very difficult to utilize the slag at present due to the high content of calcium oxide,iron and the low content of vanadium.In view of the problems of the existing vanadium extraction technologies and the characteristics of vanadium-bearing steel slag,a new technology for extracting vanadium from V-bearing steel slag through combined process of beneficiation and metallurgy has been developed,and emphatic study on the pretreatment by beneficiation,selective stage leaching,purification and enrichment was carried out.Finally,better results were achieved.Compared with total vanadium recovery of less than 70% when extracting vanadium from V-bearing solid waste by traditional processes,the index of vanadium extraction for the new technology is greatly improved with total vanadium recovery of 80%.And the new technology would have broad development potential due to the cancellation of the roasting process,which not only increases the leaching index,but also saves a lot of equipment investment and decreases the pollutants discharge.Moreover,raw material used in the new technology is vanadium-bearing steel slag rather than vanadium slag.Thus the new technology is one of the waste utilization technologies,having great significance in the full utilization of vanadium resources.
