Abstract
Laser-induced breakdown spectroscopy (LIBS) is an atomic emission spectroscopy technique suitable for in-situ and in-line measurements during pyrometallurgy. A mobile prototype system was developed to measure elemental compositions of molten metals. An inert gas flows through a tube with its end immersed in molten metal and the gas bubbles out below the melt surface. The LIBS measurement is made through the tube and onto the bubble’s surface. This avoids measuring surface contaminants and slag. This paper presents the simultaneous measurement of Cu, Ni, Fe, Co, and S concentrations in molten matte at 1,125°C.
