The occurrences and environmental effects of 12 kinds of trace elements in Huainan coal-mining area

  • 摘要: 为研究淮南矿区煤中微量元素的赋存状态和环境效应,在淮南矿区7个矿井共采集17个样品,采用电感耦合等离子质谱仪(ICP-MS)测定了12种微量元素的含量,分别利用聚类分析和因子分析,结合其地球化学性质,讨论了它们的赋存状态,并采用静态燃烧实验研究其挥发性。结果表明:研究的元素没有异常富集;Zn和Cu赋存于闪锌矿中,Cr、Pb和Cd被粘土矿物吸附,Ba可能赋存于铁白云石和方解石中,Ni、Mo、Co和As主要赋存于黄铁矿中,Be和Se以有机结合态存在;研究的元素大多不易挥发,但Zn和Pb易挥发,且含量较高,环境危害较大,Zn和Pb分别赋存于闪锌矿和粘土矿物中,可通过洗选脱除减小其危害。
    Abstract: In order to study the occurrences and environmental effects of trace elements in Huainan coal-mining area, 17 samples were collected from 7 mines in Huainan coal-mining area. 12 kinds of trace elements were deter-mined by the inductively coupled plasma mass spectrometry. Combined with the geochemical characteristics, the occurrences of trace elements were researched by cluster and factor analysis, and its volatilities were studied by static combustion. The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.
