Abstract
Extraction of vanadium from ferrovanadium slag by the process of roasting calcification -acidic leaching was researched.The influences of several parameters on extraction of vanadium were examined by condition experiments.The results show that by the process,under the conditions of pellet size of ferrovanadium slag of 8~10 mm,calcium oxide accounting for 14% of slag,sulfuric acid concentrate of 120 g/L,roasting temperature of 900 ℃,leaching time of 4 h,the ratio of liquid volume-to-solid mass of 2:1 and leaching temperature of 95 ℃,the leaching of vanadium is over 95%.The process is convenient and economic benefits is good.关键词
