铋铅中金银分析方法探讨

Discussion on the Analysis Method of Gold and Silver in Bismuth Lead

对铋铅中金银含量的测定方法进行了探讨,提出了在小瓷坩埚中利用少量的造渣剂采用火法试金法对铋铅中金银进行捕集回收,再分别测定其中金银含量。试验结果显示,该方法简单、快速,成本低,且精密度和准确性很好,能很好地满足生产经营需要。

In this paper,the determination method of gold and silver content in bismuth lead is discussed,and a small amount of slag making agent in small porcelain crucible is used to capture gold and silver in bismuth lead by fire test method and then determine the content of gold and silver respectively. The experimental results show that the method is simple,fast,low cost,precise and accurate,and can well meet the needs of production and operation.
