摘要： The process of acid leaching of calcification roasted vanadium slag was studied. The effects of process parameters variation on phase of the vanadium leaching residue, leaching rate of vanadium and the reason of vanadium loss were analyzed. The results showed that the main phase of vanadium leaching residue was insoluble in acid of dense solid solution R2O3 and Fe2TiO5, which was also mixed with silicate pyroxene phase and small amount of vanadate phase. The vanadium leaching rate first increased and then decreased with raising the roasting temperature, roasting time and the CaO/V2O5 mass ratio. Silicate species and its effect on vanadate, spinel oxidation incomplete, vanadium and vanadium bronze solid solution in of R2O3, and the difference of best leaching acidity of Ca3V2O8, Ca2V2O7 and CaV2O6 were the causes of vanadium loss.
