X荧光分析仪在普朗铜矿的应用

Application of X fluorescence analyzer in Pulang copper mine

在普朗铜矿试生产过程中,利用牛津X-MET7000手持式荧光分析仪分析地质样品,并与化学分析方法进行对比实验研究,实验结果表明:将测试样品研磨至-40目粒度后进行X荧光分析,样品内、外检检合格率分别达到90%、85%以上,测试结果能保证在24小时内获得。采用X荧光分析代替化学分析,不仅可以降低加工化验的劳动强度,节约成本费用,而且能够提高工作效率,及时指导普朗铜矿采矿生产。

The Oxford X-MET7000 hand-held fluorescence analyzer was used to analyze geological samples in the pilot production process of Plang copper mine,and the results were compared with chemical analysis methods.The results showed that the qualified rates of internal and external inspection were 90%and 85%respectively after grinding the samples to-40 mesh size.The test results can be guaranteed within 24 hours.The use of X-ray fluorescence analysis instead of chemical analysis can not only reduce the labor intensity of processing and testing,save costs,but also improve work efficiency and timely guide the production of Pulang copper mine.
