Abstract: As a secondary resource with high recycling value, red mud is rich in various valuable metals such as aluminum, iron and titanium, as well as many rare earth elements like scandium, yttrium, cerium and lanthanum. At present, the titanium is widely used in various fields at home and abroad, as well as the scandium is expensive due to its scarcity. As an alkaline solid waste, red mud is an important raw material containing scandium and titanium, which should be used to alleviate the lack of resources and improve the environment. In this paper, the current research status of the recovery of scandium and titanium in red mud at home and abroad was reviewed, and the problems of each process were pointed out. Meanwhile, the prospect of selective recovery of scandium and titanium in red mud was proposed.
