摘要:
针对某含铜金矿石在全泥氰化浸出过程中，存在氰化钠用量过高，金、铜、硫和铁等有价金属难以综合回收的问题，采用新型工艺流程进行选别。试验结果表明：经混合浮选—浮选精矿焙烧酸浸提铜—酸浸渣氰化浸出提金—浮选尾矿环保提金工艺流程，金、银、铜和硫回收率分别为94.38 %、92.01 %、89.19 %和95.12 %；并且可以获得铁品位为65.85 %、产率为30.05 %的铁精矿，实现了含铜金矿石中有价元素金、铜、硫和铁的综合回收，显著提高了经济效益和资源利用率。

Abstract:
In response to the problem of excessive sodium cyanide consumption and the difficulty in comprehensive recovery of valuable metals such as gold,copper,sulfur,and iron in a copper-bearing gold ore during the all-sliming cyanide leaching process,a new process flow is adopted for beneficiation.The experimental results indicate that through a process flow consisting of bulk flotation-copper extraction from flotation concentrate by roasting and acid leaching-acid leaching tailings cyanide leaching for gold-environmentally friendly gold extraction from flotation tailings,the recovery rates of gold,silver,copper,and sulfur are 94.38 %,92.01 %,89.19 %,and 95.12 %,respectively;furthermore,an iron concentrate with an iron grade of 65.85 % and an iron productivity of 30.05 % can be obtained,achieving comprehensive recovery of valuable elements such as gold,copper,sulfur,and iron from the copper-bearing gold ore and significantly improving economic benefits and resource utilization.
