我国铜矿尾矿资源化利用技术现状及进展

Present Situation and Progress of Resource Utilization Technology of Copper Tailings in China

这是一篇矿业工程领域的论文。我国铜矿尾矿资源主要集中在华东地区、西南地区及中南地区,以干式堆存于排土场或湿排于尾矿库,由于缺乏多梯度多方向的利用模式,给矿区周边环境及安全带来极大的威胁。加强国内铜矿尾矿资源化利用技术攻关,实现其规模化消纳,是保障矿区资源与环境安全的重要举措。本文介绍了铜矿尾矿资源概况及分布,综述了铜矿尾矿在有价元素回收、建筑材料、充填、复垦等方面的利用现状,并对铜矿尾矿资源利用存在的问题进行了探讨与合理开发利用进行了展望,为铜矿尾矿资源化技术的进一步研究及应用提供参考依据。

This is an essay in the field of mining engineering.Copper tailings are mainly concentrated in east China,southwest China and central South China,which are stored in dry dumps or wet discharge in tailings pond.The lack of multi-gradient and multi-direction utilization mode,brings great threat to the environment and safety around the mining area.It is an important measure to ensure the safety of resources and environment in mining area to strengthen the technical research on the utilization of domestic copper mine tailings and realize its large-scale consumption.This paper introduces the general situation and distribution of copper mine tailings resources,summarizes the utilization status of copper mine tailings in valuable element recovery,building materials,filling,reclamation and other aspects,and discusses the existing problems in the utilization of copper mine tailings resources and gives a prospect of reasonable development and utilization,providing a reference for further research and application of copper mine tailings resources.
