摘　　要：钽铌尾矿高效综合利用是钽铌矿山企业向绿色、低碳、循环发展转型的重要途径之一。在对我国钽铌资源及其选矿技术进行简要概述的基础上,详细阐述了我国钽铌尾矿的综合利用方式,包括再选回收有价矿物(如钽铌、锂云母、长石、石英等)、制备绿色建材(如微晶玻璃、发泡陶瓷)以及尾矿回填等方面。同时,分析了综合利用途径中存在的优势和不足。最后,提出了加强钽铌尾矿整体深度清洁回收研究和拓展钽铌尾矿制备高值化绿色建材新途径的建议,以期实现钽铌尾矿的真正资源化、减量化、无害化利用。The efficient comprehensive utilization of tantalum-niobium tailings is one of the important ways for tantalumniobium mining enterprises to transform towards green,low-carbon,and circular development.Based on a brief overview of China′s tantalum-niobium resources and beneficiation technology,this article elaborates in detail on the comprehensive utilization of tantalum-niobium tailings in China,including resource reuse-reselection and recovery of valuable minerals such as tantalumniobium,lithium mica,feldspar,and quartz,high-value utilization-preparation of green building materials such as microcrystalline glass and foamed ceramics,as well as tailings backfilling.At the same time,the advantages and disadvantages of the comprehensive utilization methods are analyzed and discussed.Finally,suggestions are proposed to strengthen the research on the overall deep cleaning and recovery of tantalum-niobium tailings,and to explore new pathways for the preparation of high-value green building materials from tantalum-niobium tailings,in order to achieve the truly resource-based,reduction-oriented,and harmless utilization of tantalum-niobium tailings.
