The various elemental behaviors of copper, lead and zinc in molten copper slags under an external electrical field at 1503 K are described. The molten copper slag cleaning process can be significantly improved by a vertical electric field. Compared to the natural settling process, the copper recovery rate increased from 20% to 92%. An external electric field in the slag cleaning process can accelerate the copper enrichment in the cathode and decrease its oxygen element content. In addition, the application of external electric fields can also be propitious for the removal of some heavy metal elements including zinc and lead.
