黔西南州黄金矿山尾矿资源的再利用

Recycling of Gold ore tailings resource in Southwest State of G uizhou Province

随着黄金生产的进程,黄金矿山排放的尾矿日益增多,堆积如山。我国把这些尾矿资源的开发与再利用作为黄金工业科技创新的工作重点之一。黔西南州的黄金资源开发,随着时日的推移,高品位矿石已不多见,多数矿山开采的原矿品位均在1g/t左右,与早年排放尾矿中金的品位相当,因此人们将注意力开始转向往日丢弃的尾矿。对于这种不能再生的矿产资源,文中提出了一个操作简单、经济合理、安全可靠的处理方法。

With the development of gold production, the gold mine tailings increase gradually. The utilization of the railings has been a new work focus of gold industry in China. With the time going, the gold mines in southwest Guizhou was degraded to a degree equivalent to that of the railings discarded years ago and ore grade of many mines are around lg/t, and the tailings discarded previously are being taken into consideration. This paper proposes a simple economic and safe method of gold mine tailings.
