从氧化铋渣中高效回收金、银、铜等有价金属的生产实践

Efficient recycling of new processes for the treatment of valuable metals such as lead, silver and gold in palladium ice copper

氧化铋渣是粗银生产过程中的一种副产品,含铋、铜、金、银等有价金属较高。本文介绍了氧化铋渣通过还原熔炼,产出粗铋和高银铋冰铜,高银铋冰铜再通过氧压浸出,铜进入溶液进行旋流电积产出阴极铜,金、银等贵金属富集到浸出渣,高银浸出渣在银冶炼直接搭配阳极泥进行富氧还原熔炼回收金、银的工业应用情况。

This paper introduces the application of oxygen pressure leaching technology in the treatment of the ice copper industry,the ice copper crushing and grinding through the sieve to-100 mesh below,sending leaching tank for acidic oxidation leaching,after enrichment containing lead,silver and other valuable metals of high silver leaching slag back to the silver smelting system to be recycled.
