摘　　要：研究了新疆省某铜矿湿法提铜工艺,采用“破碎-酸浸”生产铜,介绍了酸度、浸出时间、浸出温度对试验结果的影响。并进行了扩大试验。试验结果表明,该铜矿酸浸提铜工艺的最佳条件是：酸用量18.3%,浸出时间3 h,温度90℃,矿样中铜浸出率达70%-78%。该工艺简便,废气、液排出量少,对环境基本无污染,有较好的经济效益。XinJiang province copper mine wet process mentions copper handicraft was studied. The copper＂breaking acid to pieces soaking＂ was adopted. The acidity, leached out time, leached out an impact of the temperature over test result were introduced. The expanding experiment was done. Test results indicated that the best of pedantic digestion of copper mine copper handicraft condition was： Sour dosages 18.3 %, Leached out time 3 h, temperature 90 ℃, Copper infusion rates amount to seventy to seventy eight percent. That process was simple and convenient. Waste gas and the liquid discharge were little. It had good economic effect.
