Large amounts of waste electrical and electronic scrap containing considerable valuable metals such as copper, tin, gold, and silver is generated in Korea. In the view of resource recycling and to protect the environment it is necessary to recover the valuable metals from waste electric and electronic scrap. Present work reports a novel pyrometallurgical process for the recovery of copper and tin from the waste electrical and electronic scrap (WEES) by utilizing the waste copper slag as a slag formative. In each set of experiment, waste electric and electronic scrap were melted with waste copper slag for 30 min at 1573 K after adding suitable amount of CaO as an additional slag formative. Based on proposed process flow-sheet, >90% of copper and >80% of tin were recovered as Cu-Fe-Sn alloy from waste electric and electronic scrap.
