摘要
从含高铜、铅、锌贵液中直接用锌粉置换回收金 ,效果差。通过在锌粉置换作业中控制Pb(AC) 2 适宜用量 ,解决了铅、锌在流程溶液体系中积累、金置换率低及影响氰化浸出问题 。
When gold is recovered from pregnant solution highly containing Cu,Pb,Zn by zinc dust precipitation,the effect is disappointing.With a certain volume of Pb(AC) 2 having been added moderately in precipitation process,many problems that Pb and Zn accumulate in process solution system,that the precipitation rate is low and that cyanide leaching is affected were solved.This improvement ensures technical index.
