Technical Poster: Applications of High-Performance XRF in Mining Laboratories
Mining laboratories offer interesting analytical challenges in the sense that their materials and products can be very varied: wide elemental coverage, wide concentration ranges and varied samples matrices, varied sizes, coatings and layers, heterogeneities and inclusions. Wavelength dispersive XRF has always been put to the test in these areas alongside other trace analysis techniques. Analytical performance of XRF instruments is being constantly advanced in order to cope with such challenges. In this technical poster, several applications are presented in which the power and flexibility of latest WDXRF spectrometers are fully exploited. Mapping of a geological sample illustrates the ability to define and locate grain boundaries and crystalline structures that are not visible to the naked eye. Figures 5 and 6 in the poster show a manganese rock sample having a clear inhomogeneous structure. XRF mapping identifies the constituents of the selected section of the sample. The interesting aspect of this analysis is the differences elemental segregations throughout the rock body. This provides basic information in order to understand how such rock formation have been formed and the chemical reaction which must have occurred during the formation.
