Compared to traditional sodium roasting, calcified roast inhibits chlorine pollution. A vanadium extraction technique based on a calcified roast is especially suitable for vanadium slag with high calcium content. In this report, V2O5 was extracted from vanadium slag by calcified roast followed by acid leaching and hydrolysis precipitation. In optimized conditions, the high silicon low vanadium slag was roasted at 850°C for 2 hours without CaO addition. The roasted materials were leached with 35% H2SO4 in a liquid/solid ratio of 5:1 (mL/g) at 95°C for 4 hours. The extraction of vanadium was as high as 97.66%. These results are instructive to V2O5 production in industry.
