Copper ore was collected from Fu Shun, Liao Ning province, China. Before HVP (high voltage pulse) pretreatment, the materials were crushed into a size of 25–40 mm. The main compositions in copper ore are quartz, feldspar, pyrite, chalcopyrite, mica, and a few other minerals. The content of quartz is highest of all of the minerals.

The feed size of the mineral was 25–40 mm. The crushed products of −4 mm were considered as the completely broken products. The crushed products of +4 mm were regarded as the incompletely broken products. Fig. 5 shows that, under lower voltage, the yield of
