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.
Read MoreA research team led by the Camborne School of Mines, part of the University of Exeter, has quantified the way in which electric pulse disaggregation can improve the liberation and recovery of foraminifera from well-cemented carbonate rocks.

Read MoreLow 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.
Read MoreDirector Dan Parvaz recently posted a quick introduction to how electric pulse fragmentation (EPF) works using the Selfrag Lab system as an example. The article can be found on Linkedin HERE.
