This paper describes experiments carried out to investigate the application of Laser-Induced Breakdown Spectroscopy (LIBS) to measure the metal grade of seafloor massive sulfides in situ as part of a deep-sea mineral processing system. In the experiment, particles of sulfide minerals containing metallic elements such as copper, lead and zinc were used. The measurements were performed in bulk liquids...
The aim of this study is to investigate the application of Calibration-Free Laser-Induced Breakdown Spectroscopy (CF-LIBS) calculations, to determine the composition of metals and minerals submerged in seawater using a long-pulse laser. The compositions of six different brass standard samples submerged in seawater calculated using CF-LIBS showed good agreement with their certified values. For analysis...
