With the red mud from Guizhou as raw material, an experiment was carried out by adopting a process of low-temperature acidification roasting followed by water leaching to recover scandium, and effects of factors, including sulfuric acid dosage, temperature and time for roasting process, liquid-solid ratio of leaching solution, leaching temperature and time, on scandium leaching rate were investigated. It is shown that after 4 h-roasting at 200 ℃ with sulfuric acid and raw ore in a mass ratio of 1∶1, and then 4 h-leaching at 80 ℃ with leaching solution and solid in a mass ratio of 6∶1, the leaching rate of scandium can be finally up to 89.10%.
