我国铜尾矿二次资源再利用技术现状

Recycling Utilization of the Cooper Tailing Resources in China

随着高品位铜矿资源的日趋枯竭,高效开发铜尾矿变得越发迫切。简要介绍了我国铜尾矿资源现状,并阐述了铜尾矿资源再利用的工艺路线及最新研究进展。在对各种铜尾矿资源再利用技术进行总结分析的基础上,得出利用多种有价离子在不同酸度下高效富集分离的无机湿化学选矿工艺是最有发展前景的技术路线。

With the depletion of high grade copper mineral resources,it has become very urgent to develop the discarded copper tailings.In this paper,the status of copper tailings in our country is described briefly and the recent advances on the processing way of copper tailings are introduced.Based on the analysis for the main developing technical routes of the copper tailings resource,the inorganic wet chemical beneficiation process which is the way to separate and enrich the valuable metal ions at different acidity efficiently from the tailings as the most promising way has been proposed.
