| Abstract: |
| Leaching effects of hydrochloric acid, sulfuric acid, and nitric acid on scandium recovery from red mud were compared. The results show that scandium leaching rate is 84% under the conditions of sulfuric acid concentration of 30%, L/S of 6, temperature of 100 ℃, and reaction time of 120 min. The significance sequence for scandium leaching is as sulfuric acid, reaction time, leaching temperature, and L/S. |
