Implication

Demonstrates an effective method for extracting valuable metals from red mud, suggesting improved resource utilization.

Key Points

  • The research aims to develop a stepwise process for the extraction of aluminum, iron, and titanium from Bayer red mud.
  • Used Bayer red mud from Guangxi, China as a raw material.
  • Employed alkali roasting-water leaching, hydrochloric acid leaching, and sulfuric acid leaching for metal separation.
  • Systematically examined the effects of process parameters on leaching efficiency.
  • Achieved leaching rates of Al, Fe, and Ti at 99.61%, 99.02%, and 92.75%, respectively.
  • Isolated titanium-rich hydrolyzate with H2TiO3 content of 89.43%.
  • Obtained a titanium hydrolysis recovery rate of 90.41% and a total Ti recovery rate of 78.65%.
