摘要
通过对几种从氯化银中提取银的方法进行比较,提出了一种新的提银方法——氯化银直接水合肼提银(无氨)。该方法与氯化银传统提银方法相比,不仅工艺简单、回收率高,同时还具有还原纯度高、易操作,以及操作环境好、生产成本低等优点,是值得推广的工艺方法。
After comparing several silver recovery method from silver chloride, the paper come up with a new recovery way-silver recovery using hydrazine. The new method compared to conventional silver recovery method has the advantages of simplicity, high recovery rate, better purity, easy accessibility, fine operation conditions and low production costs. It is a method worth promoting.
