| 摘 要： | 砷是一种高危害的环境污染物,它以各种化学形态赋存在矿山尾矿中。稳定态的砷对环境的危害性较小,而活性态的砷会释放进入周围水体和土壤,对生态环境造成破坏。本文概述了砷的基本性质、尾矿砷的污染状况及研究现状、研究内容和研究意义,并以广西钟山珊瑚矿为例,探讨氧化物型尾矿中砷的富集与迁移机制,为该类型尾矿砷污染防治提供依据。

| Abstract: | Arsenic is a kind of high hazard environmental pollutant, it exits in mine tailings as various forms of chemical speciation. The arsenic in steady state does less harmful to the environment, but the arsenic in active state will release into the surrounding water and soil, and it is damaging to ecological environment. This paper summarizes the basic properties of arsenic, the pollution and research situation of arsenic in the mine tailings, the research content and significance, and aimed at the coral mine in Guangxi as an example to discuss the enrichment and migration mechanism of As in oxide tailings. The result can provide basis for this type of tailings heavy metal pollution prevention and control. |
