| 摘 要： | 针对焙烧—氰化法银回收率偏低的问题,在金精矿焙烧时加入钠盐,可有效提高焙烧—氰化银的浸出率。该方法应用于不同类型金精矿的生产实践表明,氰化银的浸出率可提高30%以上,且不影响制酸和金、铜的回收。

| Abstract: | The silver recovery rate of traditional roasting-cyanidation technique is relatively low.The author added sodium salt in roasting process of gold concentration and the cyanidation recovery rate of silver was obviously enhanced.The method is suitable for different kinds of gold concentrate,whose silver recovery rate can be raised by 30%.Meanwhile,both acid making and gold,copper recovery will not be influenced. |
