摘　　要：对南京栖霞山锌阳矿业有限公司铅锌矿选矿尾矿的处理与利用进行了研究 ,找到了一条解决选矿尾矿问题的最佳方案 :对尾矿进行分级处理 ,粗粒尾矿代替水砂用于井下充填打坝 ,细粒尾矿用于井下胶结充填 ,部分全尾矿浓缩脱水后用作水泥辅料 ,从而实现了尾矿固体废物的零排放。该方案已成功应用于生产实践 。The disposal and utilization of tailing waste from Nanjing Xixiashan Xinyang Mine Company are investigated. The optimal scheme of solving the taitings is found out. The large part of tailing is classified. The coarse particles substituted for sand and are used to build a dam of mine well fill. The fine particles are used as a material of cementation fill of mine well. The small part of tailing is thickened and is used as cement assistant. The zero discharge of tailing waste is obtained. The scheme has been used successfully in production with obvious economic and environmental benefits.
