Evaluation of Portable X-ray Fluorescence Analysis and Its Applicability As a Tool in Geochemical Exploration

Large-scale, high-density geochemical explorations entail enormous workloads and high costs for sample analysis, but, early mineral exploration, absolute concentrations are not essential. Geochemists require ranges, dynamics of variation, correlations rather than accuracy. Thus, higher work efficiency lower analysis desirable exploration. This study comprehensively analyzed the reliability applicability portable X-ray fluorescence (pXRF) spectrometry in The results show that pXRF can be applied effectively to rock powder samples, preparation a longer detection time have been shown increase precision results. When is used on if less 30% samples assessed as containing an element, element usually undetectable using when these prepared powders, indicating data about detected unreliable; thus, it suggested some representative should selected testing before starting use exploration project. In addition, although extended increased results, more 80 s did significantly affect accuracy For this reason, recommended study. has advantages being low-cost, highly efficient, stable, its reliable enough exhibit spatial distribution indicator elements (arsenic, nickel, lead, sulfur, titanium, zinc) polymetallic mineralization Therefore, recommendable practical
