Abstract

Abstract

In this article, vanadium is extracted from a vanadium-bearing stone coal in Shanyang by the process of melt-roasting-water leaching. The experimental roasting and leaching conditions were optimized, including sodium peroxide dosage, roasting time, roasting temperature, leaching method and ash treatment. The results showed that the leaching rate of vanadium was maximum when the dosage of sample and sodium peroxide was 1∶3, roasting temperature was 700 ℃ and roasting time was 7 min. The concentrations of vanadium in the leaching solution were found to be 1.38 mg/L in the leaching samples at the optimum working conditions.
