Background

Elemental analysis is important in the analysis of ores, from screening at the mine site and throughout the processing areas to final analysis. Majors and minors are important during processing, to ensure proper extraction and process control. Trace elemental analysis, especially of precious metals, is also extremely important to ensure the value of the processing is optimized. In lead/zinc ores the money elements are lead, zinc and in some ores silver, as well. Along the entire processing line, a fast and simple technique is required to monitor these and other elements. Rigaku offers the NEX CG EDXRF elemental analyzer to meet these industry challenges. The NEX CG, using indirect excitation and polarization, is a powerful, yet simple tool for the measurement of the elements sodium through uranium in rocks and ores.
