Abstract AITranslate

Vanadium was recovered by two-stage hydrochloric acid leaching of alumina red mud, with vanadium leaching rate up to 97.96%. The resultant leached solution was evaporated,thickened and purified before 3-stage extraction with 100% amyl acetate,with V extraction rate up to 95.67%. 3-stage countercurrent stripping of the loaded organic phase was carried out with 10% NH4OH solution, with vanadium stripping rate up to 97.23%. The product containing 98.50% V2 O5 can be obtained by ammonium salt precipitation and thermal decomposition of stripping aqueous phase, and the overall vanadium recovery is up to 82.69%.
