UTILIZATION OF LASER-INDUCED BREAKDOWN SPECTROSCOPY (LIBS) FOR FAST ONLINE DETERMINATION OF ELEMENTS OF INTEREST IN MINERALS

Popis výsledku v původním jazyce

We report on the utilization of Laser-Induced Breakdown Spectroscopy (LIBS) for determination of elements of interest in minerals. LIBS is a simple atomic emission spectroscopy technique capable of real-time, essentially nondestructive determination of the elemental composition of any substance (solid, liquid, or gas). This technique is presently undergoing rapid research and development among others as the method for geochemical analysis. LIBS has attractive potential as the field tool for rapid man-portable and/or stand-off chemical analysis. In this work we focused on the determination of the spatial distribution of precious metals (Pt, Ni, etc.) in the ore cross-section. As reference techniques for LIBS, Energy dispersive X-ray spectroscopy (EDS) and TESCAN Integrated Mineral Analyzer (TIMA) were utilized. For localization of metal structures inside the mineral sample microCT system was used. The advantages and disadvantages of combining LIBS with microCT will be detailed.
