摘要:

采用火焰原子吸收光谱法测定低品位金矿石中金,从加工粒度、焙烧条件、活性炭吸附回收率和原子吸收分光光度计期间核查等4个方面进行最优测定条件的探究,分析了低品位金矿石测试分析过程中的相关误差来源,并进一步优化了实验测试方法和流程,提高了测试数据的稳定性。本方法测定结果的相对标准偏差(n=10)小于1 %,准确度和精密度较高,且简单、实用,满足矿山生产技术指标测定需求。

Abstract:

Flame atomic absorption spectrometry was used to determine gold in low-grade gold ore.The optimal measurement conditions were explored from 4 aspects:processing particle size,roasting conditions,activated carbon adsorption recovery rate,and atomic absorption spectrophotometer verification during experiments.The sources of relevant errors in the analysis process of low-grade gold ore were analyzed,and the experimental testing method and process were further optimized to improve the stability of the testing data.The method has high accuracy and precision,with a relative standard deviation (n=10) of less than 1 %,and is simple,practical,and suitable for the measurement requirements of mining production technical indicators.
