| Abstract: |
| Through analysis of the phase composition and distribution state of scandium in red mud, itSputSforwardSthat titanium white waste liquid leaches of red mud for extracting scandium. The experimental results show that influence factor of scandium leaching rate are liquid-solid ratio, leaching temperature and leaching time. Under the condition of liquid-solid ratio is 3:1, leaching temperature is 60℃ and leaching time are 30 minutes, the filter performance and leach liquor stability are very good, the leach liquor acidity is 3.62N, scandium concentration is 28.4mg/L and scandium leaching rate is 69.75%. |
