Investigation of Potential of Laser-Induced Breakdown Spectroscopy for Detection of Spatial Deposition and microCT for Volume Deposition of Pt in Minerals/Ores

Popis výsledku v původním jazyce

The platinum group metals (PGMs) i.e. platinum, palladium, rhodium, iridium, osmium and ruthenium represent the key materials for automotive exhaust gas treatment. Since currently exist no adequate alternatives, the importance of these metals for automotive industry is steadily rising. In order to localize new ore deposits it is important to develop suitable methods capable to detect critical metals in real time, even in extremely harsh climatic conditions of some ore deposit sites. In this paper we demonstrate that laser-induced breakdown spectroscopy (LIBS) can be applied as a suitable tool for elemental analysis, especially for 2-dimensional elemental mapping of minerals. In order to obtain the information about metals distribution in the sample volume, the microCT station has been utilized. We focused on sperrylite detection, which is a simple platinum arsenide with the chemical formula PtAs2 obtained from unique Talnakh deposit (Siberia, Russia).
