| Abstract: |
| Sc2O3 with purity of 99.99% was prepared with titanium white waste acid and red mud as raw materials by processes of leaching, first-stage extraction and stripping, dissolution and hydrolysis, secondary extraction, acid washing, secondary stripping, oxalic acid precipitation and refining. The recovery of scandium from red mud and titanium white waste acid is 57.8% and 93.3% respectively. |
