| 摘 要： | 广西南丹地区尾矿分布于大厂、车河、芒场等矿区。尾砂来自以锡石为主的多金属矿床，尾砂中除Sn，Pb，Zn，Ag，Sb的质量分数达到工业指标外，Au亦达到综合利用指标。通过试验证明，对尾矿中的细微粒锡石可采用风力分级选矿、磁选和化学选矿等方法回收；尾砂中的非金属资源可作为填充材料、水泥原料利用，使尾砂型人工矿床充分的资源化。

| Abstract: | Tailing dams are built in Dachang, Donghe, Mangchang mining districts in Nandan area, Guangxi province. They are tailing of polymetal deposits dominated by cassiterite. Sn, Pb, Zn, Ag, Sb concentrations of tailing reach the industrial index, Au also to the index. Experiments show that the finemicro-grain size cassiterite can be recovered by step-air flow, magnetic beficiation methods. In addition to the metals non-metal materials can he recovered as filling material and raw materals for cement. |
