应用X射线荧光光谱仪监控铜选矿流程,采用粉末压片法制样,确定了仪器最佳参数,建立了校准曲线。经北京矿业研究总院验证,原矿偏差小于±0.024%,尾矿偏差小于±0.004%,精矿偏差不大于士0.127%;相对标准偏差(n=9)≤1.76%。大量实验数据表明,粉末压片制样-X射线荧光光谱法测定流程原矿、尾矿、精矿中的铜的准确度、精密度均可满足对选矿的监控。 The process of copper beneficiation was monitored by X-ray fluorescence spectrometer. The sample was prepared by powder tablet method, the best parameters of the instrument were determined, and the calibration curve was established. The Beijing Mining Research Institute verified that the ore deviation less than ± 0.024%, tailings deviation less than ± 0.004%, concentrate deviation of not more than ± 0.127%; relative standard deviation (n = 9) ≤ 1.76%. A large number of experimental data show that the powder pellet preparation-X-ray fluorescence spectrometry process ore, tailings, copper in the concentrate accuracy and precision can meet the dressing monitoring.
