Abstract

AbstractThe recent progress in electrical comminution using high‐voltage pulses and the technical challenges in order to bring this technology to the mining industry are outlined. Pre‐weakening ore particles and preferential liberation of minerals at coarse sizes are the two major research outcomes that may have potential benefits for the industry. A particle pre‐weakening characterization method by single‐particle/single‐pulse test has been developed. The emerging challenges for the mining industry to realize the benefits of this novel comminution technology include scale‐up for industrial application, hybrid circuit design, maximization of pulse‐induced cracks, and study of the downstream processing effects.
