摘要
本文主要介绍了针对四川某金矿含铜较高、影响氰化浸金而进行的除铜浸金工艺研究。结果表明：采用含氨溶液预处理除铜，有效地排除了铜对氰化浸金的影响。同时成功地从氨浸铜溶液中沉铜再生氨，不仅综合回收铜，而且使再生氨液返回循环浸铜，降低了预处理成本。
A new technology for heap leaching of a copper gold ore was described in this paper.Test results showed that use of ammoniacal solution pretreatment can effectively remove copper,and thus alleviating negative effect of copper on leaching of gold.Meantime,regeneration of ammonia from ammoniacal solution of leached copper was successfully achieved.
