有色金属尾矿中镓的分析方法对比研究

Comparative Study on the Gallium Analysis Methods for Its Recovery from Non-ferrous Metal Tailings

尾矿中有价金属资源的回收利用不仅可实现资源的回收利用,同时缓解甚至消除尾矿带来的环境危害、安全隐患。镓是有色金属中最为常见的伴身元素之一,具有较高的回收利用价值,尾矿矿物组成复杂,且作为伴生元素的镓含量本身较低,目前对尾矿的镓含量测定缺乏系统理论研究,导致我国尾矿尾镓回收研究较为落后。随着镓的用途的不断扩展,如何测定复杂矿物中少量、微量甚至痕量的镓对尾矿镓的回收利用显得非常重要。文章综述了镓的常见测定方法,结合尾矿矿物性质,对比分析了不同方法的优缺点,并结合试验实际,分析了尾矿镓含量分析测定的方法。

With the recovery technology, the metals resources could be recycled from the tailing, the environmental risks and the safety risks brought by the tailing restoring would be eliminated either. Gallium was the typical associated element of the nonferrous metal tailing; it has great value for recycle. But, its content was hard to analysis, the reason was that, the mineral composition was complicated and the content was low. While, the gallium recovery was so important for the tailing reuse and also its value. How to analysis its content within the tailing was more and more important. The analysis method for the gallium detection was elaborated in the manuscript, and the merit was compared within the different methods. Some method was recommended for the gallium analysis of the nonferrous metal mine tailings.
