| 摘 要： | 尾矿中高含量重金属具有潜在的资源和环境意义。通过分析拉拉铜矿尾矿中的重金属含量及其赋存形式,讨论了尾矿中有价元素的回收利用可能性,并评价了尾矿中重金属的生态风险。结果表明,拉拉铜矿各期尾矿中仅Ⅲ期尾矿的铁、铜、钴具有综合利用价值;各期尾矿中多种重金属元素潜在的生态危害程度轻微,但是各期尾矿中汞的生态危害程度中等,Ⅲ期尾矿中铜的生态危害程度中等。因此,矿区不仅要注意各期尾矿汞对环境的潜在污染,同时也应注意Ⅲ期尾矿铜对环境污染的生态风险。

| Abstract: | The heavy metals in mine tailings have potential resource and environmental significance.The content of heavy metals and their speciation in Lala copper mine tailings was analyzed,the possibility of the valuable element from the mine tailings recycling was discussed and the ecological risk of heavy metals was evaluated.The results showed that only Fe,Cu,Co in Lala copper mine tailings Ⅲ had comprehensive utilization value,and the potential ecological risk of most heavy metals in the tailings is slight,however,the ecological risk of Hg in all of the tailings and the ecological risk of Cu in tailing Ⅲ were in moderate level.It suggested that the potential environmental pollution of Hg in the mine tailings should be concerned,and the ecological risk of Cu in tailings Ⅲ also should be paid enough attention. |
