摘要
从铅锌尾矿有价资源再选、建筑材料应用与采空区回填几方面入手,介绍了国内对铅锌尾矿的综合利用现状。铅锌尾矿再选有价资源主要有铅、锌、硫、萤石、重晶石、绢云母等,铅锌尾矿在建筑材料上主要是用于生产水泥、墙体材料以及作为活性混合材,采空区回填则是实现矿区可持续生产的可行途径。
Some technologies in utilization of lead-zinc ore tailings solid wastes in china are introduced. The comprehensive recover process is used for recovering valuable elements such as Pb,Zn,Ag,S and so on from mill tailings. The tailings as raw material uses for cement mixture concrete aggregate and block brick aggregate respectively. And for utilizing the tailings as the backfill material into mined-out areas.
