铜尾矿中的污染源分析及其安全处置方法研究

Analysis of pollution sources in copper tailings and research on its safe disposal methods

铜矿开发利用过程中,不可避免会产生大量的尾矿,铜尾矿的随意堆弃会对周围生态环境造成不良影响。以某铜尾矿堆场为例,对其周边的土壤进行了采样分析,明确了主要的污染源。结果发现,Cu、As和Cd元素是铜尾矿中的主要污染源,Ni元素是次要污染源。结合铜尾矿实际情况,提出尾矿的安全处置方法。通过对铜尾矿的处置,不仅可以对其进行再利用,同时还可以有效改善生态环境。

During the development and utilization of copper mines,a large amount of tailings will inevitably be produced.The random dumping of copper tailings will cause adverse effects on the surrounding ecological environment.Taking a copper tailings yard as an example,the surrounding soil was sampled and analyzed to identify the main sources of pollution.It was found that Cu,As and Cd elements are the main pollution sources in copper tailings,and Ni elements are the secondary pollution sources.Combined with the actual situation of copper tailings,the safe disposal method of the tailings is proposed.Through the disposal of copper tailings,not only can it be reused,but also the ecological environment can be effectively improved.
