摘要
本文主要研究了火试金法分析铜精矿中Au、Ag时,在同一试样情况下,不同的试样粒度对Au、Ag分析结果的影响,证实铜精矿试样粒度为180目时,火试金法分析的Au、Ag结果具有最好的精密度和准确度。
The influence of sample granularity on the analysis results was investigated during the determination of gold and silver in copper concentrate in fire assaying method. The results indicated that the determination of gold and silver in copper concentrate in fire assaying methods was better in precision and accuracy when the sample granularity of copper concentrates was about 180 mesh.
