Phase structures and spinels’ particle size of water-cooled vanadium slag,air-cooled vanadium slag and slowly cooled vanadium slag are analyzed,and the effect of holding time at 1 000 ℃ under nitrogen atmosphere on particle size of the vanadium spinel is studied.In addition,comparisons of sodium roasting of water-cooled vanadium slag,air-cooled vanadium slag and slowly cooled vanadium slag under the same conditions are made.According to the research,slow cooling and holding at 1 000 ℃ benefits the growth of vanadium spinel particles;for the vanadium slag of-0.125 mm roasted without vanadium extraction tailings,the conversion rate of water-cooled vanadium slag at different size range is 1%~2% lower than that of slowly cooled vanadium slag at the same size range;for the vanadium slag of-0.125 mm roasted with vanadium extraction tailings,the conversion rate of water-cooled vanadium slag is 0.56% lower than that of slowly cooled vanadium.
