Study on Recovery of Vanadium from Low-Vanadium Slag by Calcified Roasting Methods

Abstract:

Vanadium was recovered by using technology of calcified roasting→alkali leaching→ion exchange→precipitating→deaminizing, the principles of this recovery process were described in detail. Through the experiments, the parameters of roasting, leaching and ion exchange were determined, a new operational, low-polluting method to recovery vanadium was formed. This method not only can overcame the disadvantage of traditional technology, such as long process, serious pollution, but also has advantages such as high recovery and high purity of vanadium. In this study, pure V₂O₅ products with national standard were obtained. The total recovery was up to 65% or more, which was higher than that of the sodium roasting methods.
