Experimental Research on Titanium Recovery from Red Mud by Acid Leaching AITranslate
Abstract AITranslate
Titanium was recovered from red mud by acid leaching with sulfuric acid,hydrochloric acid or nitric acid as the leaching agent.The effects were investigated of kind and concentration of leaching agents,liquid to solid ratio,leaching temperature and reaction time on titanium recovery.The results show that sulfuric acid is more appropriate as the leaching agent.The leaching rate of titanium reaches 90% under the conditions of sulfuric acid concentration 40%,leaching temperature 100℃,liquid to solid ratio 6∶1and reaction time 60 min.Brookite and calcite disappear,perovskite,hematite and cancrinite decrease and anhydrite forms during acid leaching.Dissolution reaction of perovskite and brookite in sulfuric acid results in titanium recovery from red mud.
