摘　　要：针对稀土尾矿有价元素残留问题,总结了稀土尾矿综合利用现状,探讨了资源二次利用的方法。分析认为:减量化处理主要针对铁、萤石等有价物质的回收;资源化手段包括胶凝材料、陶瓷、玻璃、催化剂的制备;无害化主要采用淋洗、植被修复等方法进行处理;今后研究应聚焦稀土尾矿有价组分高效、低成本、绿色分离,开发高附加值利用新途径。Aiming at the problem of valuable elements remaining in rare earth tailings,the present situation of comprehensive utilization of rare earth tailings was summarized.The methods of secondary utilization of resources were discussed.The analysis shows that the reduction treatment is mainly for the recovery of valuable elements such as iron and fluorite.Resource utilization means include the preparation of 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 green separation of valuable elements from rare earth tailings and developing new ways of high value-added utilization.
