中文摘要: 提出一种新型的选择性抑铜浸金新工艺处理含铜氧化金矿，该工艺加入抑浸剂(MZY)后进行氰化浸出，可达到抑铜浸金的效果，并对工艺参数进行优化。结果表明，当石灰、MZY和氰化钠用量分别为18、0.5和1.2 kg/t时，金、铜浸出率分别为83%~84%和4%~5%，新工艺的金浸出率高、铜抑制效果好、操作简单。
Abstract:A new process to leach gold from copper-bearing gold refractory ore was put forward. Copper was inhibited with depressant (MZY) and gold was selectively cyaniding leached. The technical parameters were optimized. The results show that the leaching rate of gold and copper is 83%~84% and 4%~5% respectively when the dosage of lime, MZY and sodium cyanide is 18, 0.5 and 1.2 kg/t respectively. The new process has the advantages of high gold leaching rate, good copper inhibitory effect, and easy operation.
