Application Note #5041 describes the analysis of copper ore concentrate, with complete information about sample preparation, method calibration and repeatability.
Analysis of copper sulfide ore, a major source of copper, and other Cu concentrates can reveal the presence of not only harmful elements, such as arsenic, but also elements more valuable than copper, including silver or gold. As the quality of Cu ore deposits has decreased, the demand for reliable analysis has increased. For the described method, fifteen copper concentrate samples were used as references for calibration and were prepared using the pressed powder technique. Calibration was performed for Cu, Zn, Pb, Bi, Ag, As and Cd using the Supermini200 with a Pd-target X-ray tube. To test the precision for Cu concentrate analysis, ten measurements were performed. The calibration accuracy obtained in the report shows performance and repeatability precise enough for daily analysis use.
The results show how, with these application techniques, a benchtop spectrometer can be a powerful tool for ore and concentrate analysis for both process control and screening. A copy of this report may be requested at: http://www.rigaku.com/products/xrf/supermini/app5041.
