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 2540 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.

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.

The first notable application for copper ore came in 1995 at the Cyprus Sierrita copper mine in the USA. However, on account of the extremely abrasive ore, no economical service lifetimes could be achieved for the grinding rolls. The breakthrough came in 2006 at the Cerro Verde copper ore project (Fig. 8) in Peru.
