    • 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.
