探讨了含铜铁矿石分析过程中的铜对铁分析的影响。分析过程中采用标准溶液模拟实验、国家标准物质中铁的容量分析、方法比对等实验,得出一个大约的经验系数R,为含铜铁矿石中全铁含量的质量控制提供参考。该系数经过对多个含铜国家标准物质中的铁进行分析验证,样正值与标准值基本相符。
The effect of copper on iron analysis in the analysis of copper-bearing iron ore was discussed. In the process of analysis, the standard solution simulation experiment, the capacity analysis of iron in national standard materials, the comparison of experiments and other methods were used to obtain an approximate empirical coefficient R, which provided a reference for the quality control of total iron in copper-bearing iron ores. This coefficient is validated by the analysis and analysis of iron in several copper-bearing national standards. The positive sample values are basically consistent with the standard values.
