Laser-Induced Breakdown Spectroscopy (LIBS) is a crucial tool for measuring elemental concentrations in various industrial applications, particularly in pyrometallurgy. This study presents a mobile LIBS prototype system designed to analyze molten metals, effectively allowing for in-situ and in-line measurements during the materials processing. The system utilizes a lance that immerses in the molten metal while an inert gas flows through to minimize contamination from slag and fluxes present on the surface. This continuous renewal of the molten surface ensures representative sampling of the bulk material. The performance of the system is demonstrated through the simultaneous measurement of concentrations of copper, nickel, iron, cobalt, and sulfur in molten matte at elevated temperatures of 1125 °C. Notably, the technology aids in optimizing industrial processes by determining the ideal moment to cease oxygen blowing in converters and facilitating accurate elemental concentration measurement during alloying. This work illustrates the utility of LIBS in enhancing productivity and cost-effectiveness within the mining industry, addressing the ongoing challenges of process optimization.
