选择性沉淀法从堆浸液中分离回收铜镍

Separating-reclaiming Copper and Nickel from Leaching-piled Liquor by Selective Deposition

根据低品位堆浸液中杂质浓度高 ,而有价金属浓度低的实际情况 ,综合目前的一些处理技术 ,在大量试验的基础上提出了分步水解除铁、活性硫沉铜、硫化沉淀法沉镍的流程来回收分离铜镍。

The content of valuable metals is lower than impurities,to reclaim valuable metals is very difficult.Thinking of factual instance and summarizing a lot of relational dealing technologies presently,on the basis of a great many experiments,the author brought forward the process to remove Iron stage by stage through hydrolyzation,to deposit Copper through active Sulfur,and to deposit Nickel through sulfuration,Copper and Nickel were separated and reclaimed at the end.
