摘　　要：论述了有色金属尾矿的特点及尾矿堆存的潜在危害,从金属组分、重晶石及萤石类物质和非金属组分回收方面系统的介绍了尾矿再选,回收有价组分的状况。同时,归纳了有色金属尾矿整体化资源化应用于建筑材料、催化剂、造肥或土壤改良剂、复垦、充填等领域的情况,并着重介绍了水泥、聚合材料、玻璃等多种以尾矿为材料制备的建筑材料。从国家"十二五"规划等政策、环境保护和矿产资源可持续发展出发,评述了有色金属尾矿综合利用的发展趋势,提出有色金属尾矿整体资源化应用在推进节能环保战略性新兴产业发展上意义深远。The characteristics of non-ferrous metal tailings and the potential hazard of the tailings impoundment were stated. Furthermore, the reconcentration of tailings and the recovery of the valuable components were introduced from the recovery of metal components, barite and fluorite substances and non-metallic components. Meanwhile, the resource application of non-ferrous metal tailings to the fields of building materials, catalyst, fertilizer or soil condi- tioner, reclamation and filling was summarized and such building materials as cement, polymeric materials and glass which were prepared from tailings were introduced. The development tendency and far-reaching of comprehensive u- tilization of non-ferrous metal mine tailings for promoting the development of strategic emerging industries for energy saving and environmental protection was critiqued and put forward in view of the Twelfth Five-Year Plan, environ- mental protection and mineral resources sustainable development.
