| 摘 要： | 拟定了一种从含碳金矿石中提取金的工艺方法，该方法采用氨水-煤油混合体系对矿样进行预处理，从而使可溶性铜形成铜氨络合物，使矿样中的碳吸附煤油而钝化，以消除碳在氰化过程中对金的吸附。在助浸剂H2O2存在的条件下，分别采用CaO和NaOH为pH值的调整剂进行氰化浸出，使金的氰化浸出率分别达到96.01%和97.79%，具有较好的经济效益和社会效益。

| Abstract: | One technique of extracting gold fl＇om carbonaceous gold ore has been intended,which pretreated ore samples using the ammonia-kerosene mixed system,and made soluble copper become to be copper ammonia complex.It enables the carbon in ore samples adsorbed kerosene and passivated,and eliminated the gold adsorption in carbon＇s cyanide leaching process.In the presence of leaching aid （H202） and using CaO and NaOH as the pH value regulator respectively,the cyanide leaching rate of gold has reached 96.01% and 97.79%.There are good economic and social benefits. |
