Researchers from EMPA and SELFRAG have trained a computer to recognise how much a piece of rock has been broken by electric pulse fragmentation by the sound of the electrical discharge. This has the potential to allow future systems to recognise how much the rocks are breaking and automatically adjust energy input to achieve target size reduction.

Low grade tungsten ores were crushed traditionally and with an electric pulse treatment stage. Electric pulse treatment made the ore weaker and concentrated W in the fine fraction, while producing less fines overall than traditional crushing.
