摘要
控电氯化金冶炼新工艺是在有色金属湿法冶金的基础上,通过控制电位,实现贵贱金属的分离。该工艺不仅能生产出高纯度的金、银,而且金、银回收率高,金的冶炼直接回收率大于99.5%,金、银的综合回收率在99%以上,同时该工艺缩短了冶炼周期,降低了生产成本。
The new technology of chloridzing gold refining with controlled electrowinning achieves separation of precious metals from base metals by means of control of voltage on the basis of non-ferrous metals＇ hydrometallurgy. This technology not only produces high purity gold and silver , but also has higher recoveries with the gold recovery being over 99.5% and the integrated recovery for gold and silver being over 99%. And further, it reduces the refining cycle and cuts operation cost.
