    Steel industry produces a large number of V-bearing converter slag, the slag with relatively high vanadium content is an important resource of vanadium, on the other hand, if it is not properly handled, which will cause heavy metal pollution. At present, the method of wet extraction vanadium is not suitable for V-bearing converter slag with relatively low grade of vanadium, it is necessar to enhance the grade of vanadium by mineral processing before leaching, while the vanadium in the slag dispersely distribute, the concentration effect of ore dressing is poor. Vanadium concentrating in one or two ore phases need to be conducted before mineral processing. Taking into account the following separation vanadium, iron spinel phase has big property difference from main phase in converter slag, which is a suitable choice for vanadium enrichment phase. Based on this, the formation of vanadium iron spinel phase in converter slag modified will be invesigated through experimental and theoretical calculation under reducing conditions in this paper. The research results show that the vanadium content in concentrating phase is more than 12%, meeting the requirement of vanadium grade of hydrometallurgical vanadium recycling.
