Abstract

Abstract: Effects of roasting temperature, roasting time, kinds and addition amount of addition and other factors to vanadium leaching rate were investigated. Results indicate that roasting temperature and time have greater influence to vanadium leaching rate, best roasting condition is 800 ℃,3 h; adding NaCl or Na₂CO₃both could increasing vanadium leaching rate significantly, vanadium leaching rate could increase 23.21 percentage reach to 84.45% by adding 2% Na₂CO₃+1% oxidant H-1.

Key words: Stone coal, Vanadium, Roasting, Leaching rate
