Abstract: Aiming at the problem of valuable elements remaining in rare earth tailings,the present situa-tion of comprehensive utilization of rare earth tailings was summarized. The methods of secondary utili-zation of resources were discussed. The analysis shows that the reduction treatment is mainly for the re-covery of valuable elements such as iron and fluorite. Resource utilization means include the preparationof cementitious materials,ceramics,glass and catalysts. The harmless treatment mainly adopts leaching,vegetation restoration and other methods. Future research should focus on efficient,low-cost and greenseparation of valuable elements from rare earth tailings and developing new ways of high value-addedutilization. Close-
