从湿法冶炼废水中回收金

The recovery of gold from hydrometallurgical waste water

介绍了用SO2 还原沉淀 ,用NaOH浸煮除杂质等工序回收湿法冶炼废水及废水沉淀物中金的过程。该工艺不仅能回收金 ,还可回收其它有价金属 (Cu、Pb) ,是一种操作简便。

Using SO 2 to reduce and sedimentate gold in hydrometallurgical wast water ,then boiling the waste water and removing impurity,the gold in the hydrometallurgical waste water can be recovered.This method can be used to recover not only gold but also other valued metals(Cu,Pb) in the waste water.It is easy to operate.
