| 摘 要： | 由于铅锌尾矿长期露天放置会对环境产生危害。通过原子吸收分光光度法、原子荧光分光光度法对不同酸静态浸泡后铅锌尾矿的浸出液测定得出,盐酸对金属离子浸出影响最大。细颗粒的尾矿更易浸出,浸出时间越长,浸出的金属含量反而降低。测定了尾矿堆附近的土壤,通过与背景值和标准对照,说明尾矿堆附近土壤已经被污染。

| Abstract: | Lead and zinc tailing discards caused the severe harm to the environment.Leaching the mine tailing by three kinds of acids,the different acids have got different results.And particle size of tailing is smaller;the concentration of the heavy metals is higher.The time is longer,the concentration of metal is lower.The concentration of heavy metals in the soil at the surrounding of mine tailings is determined;the soil is contaminated compared by background. |

| Keywords: | mine tailing heavy metal environment pollution |
