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.
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。
