细菌浸铜技术在紫金山铜矿的应用

The Application of Bacterial Copper-leaching Technique in Zijinshan Copper Mine

介绍了生物浸矿技术在紫金山铜矿的应用及在这一过程中发现的一些问题 ,并提出了有待进一步解决的一些问题。

Bacterial leaching is a new technique developed in recent tens of years,it is a flow sheet of using animalcule and its metabolized products to oxidize and melt the target compositions in the ores. It is advantageous of low cost,minor environmental pollution,easy operation,capable of treating difficult oxidized ores,mixed ores,poor ores,useless ores,spoil ores,tailings,copper bearing slag,residuals in the mined out area and pit residuals. So, the technique triggers a wide notice of the world,and it is developing rapidly in the latest twenty years,and there is about 20%～30% of the world’s copper output is dressed by bacterial leaching. The text illustrates the application of bacterial leaching in the copper mine of Zijinshan and some issues occurred in the course of application. In conclusion, some issues remain to be solved are advanced in the text. [WT5HZ]
