重金属污染在尾矿库中非常普遍,重金属污染分析和评估是尾矿库回收利用的基础工作。对此,本文对海南不同金矿尾矿的重金属含量进行系统分析。结果发现,As浓度过高,导致不同尾矿库的重金属含量出现异常峰值;三种重金属污染特色的评价结果表明,As污染危害性非常严重,需要在今后的回收利用中进行深度处理。 Heavy metal pollution is very common in tailings ponds, and the analysis and assessment of heavy metal pollution are the basic work for recovery and utilization of tailings ponds. In this regard, this paper systematically analyzes the heavy metal content of different gold mine tailings in Hainan. The results showed that As concentration was too high, resulting in abnormal peak of heavy metal content in different tailings ponds. The evaluation results of three heavy metal pollution characteristics showed that the As pollution hazard was very serious and needed to be dealt with in depth in future recycling.
