| 摘 要： | 某铜矿石铜品位低,氧化率高,碱性脉石含量高,嵌布粒度很细,属于典型的难处理氧化铜矿。采取常温常压氨浸法处理,系统地考察了浸出过程中诸因素对铜浸出率的影响。试验结果表明,游离氧化铜浸出率达84%以上。结合氧化铜浸出率达10%以上。

| Abstract: | The oxidized copper ore is low copper grade,complex minerals composition,fine-grained dissemination,high oxidation level,and high content of alkaline gangues.The ore is refractory.This ore is leached with ammonia at normal temperature and pressure,and the effects of several factors on the copper leaching ratio are investigated.The results show that leaching ratio of free oxidized copper is over 84%,and that of combined oxidized copper is over 10%. |
