从文峪金矿含铜低金硫精矿中提取金铜的工艺研究

Study on gold and copper extaction from copper-bearing low gold-sulfur concentrate in Wenyu Gold Mine

通过分析影响含铜金硫精矿常规氰化提金的因素 ,提出用浮选方法把含铜金硫精矿分成金铜精矿和金硫精矿 ,金铜精矿用加压氧化酸浸法提铜 ,提铜渣和金硫精矿分别用常规氰化法提金 ,该工艺消除了铜对氰化过程的影响 ,取得了满意的技术经济指标。

Through analysis of the factors influencing cyaniding from copper bearing gold sulfur concentrate,this paper proposed to divided this concentrates into gold copper concentrate and gold sulfur concentrate by way of flotation.The copper was extracted from gold copper concentrate by pressure oxidizing acid leaching process and the gold was extracted from copper residue and gold sulfur concentrate by conventional cyanide process.By this process flow,the influence of copper on cyanidation was remvced,gaining satisfactory techno economic index.
