德兴铜矿含铜废石细菌浸出试验研究

Tests on Bioleaching of Copper from Waste Ore at Dexing Copper Mine

利用细菌的作用对低品位硫化铜矿石进行浸出 ,能有效地促进硫化铜矿物中铜的浸出 ,提高铜浸出率。介绍了几种有利于铜矿物浸出的试验方法 ,从试验结果可知 ,每一种方法对硫化铜矿物的浸出都有一定效果 ,如能进一步深化该项研究 ,将对堆浸提铜技术的发展起促进作用。

It is effectively on accelerating leaching speed of copper sulfide and increasing leaching rate of copper that bacteria acts on low grade copper sulfide ore.Several experimental methods on leaching of copper are introduced in this paper.Each method is effectively for recovery of copper from waste ore containing copper.If further studies are dong,leaching technology of copper will be improved.
