摘要
冰铜作为铜冶炼的中间产品,样品中铜含量偏高,用火试金法富集样品中的金和银时容易因为除铜不干净导致最后的金、银分析结果偏低,本报告从影响火试金法测定冰铜中金和银量分析步骤的各个环节进行条件试验,综合考虑分析的准确度以及成本控制,给出最适合冰铜中金银分析测试的各项条件,给日常生产一定的指导意义。
As an intermediate product of copper smelting,the copper content in the sample is high,and it is easy to enrich Jinhe silver in the sample by fire test gold method.Because the final gold and silver analysis results are low due to the uncleanliness of copper,this report determines the gold and silver content of ice copper from the influence of fire test gold method.The most suitable for the gold and silver in the ice copper is given,considering the accuracy and cost control of the analysis.Analysis of the conditions of testing,to daily production of a certain sense of guidance.
