In recycling copper scrap, the removal of impurity elements is a critical subject for the purpose of ensuring product quality. In the current investigation, lead and nickel in copper, the removal of which has long been considered difficult by conventional pyrolysis, were successfully and simultaneously removed by the very simple method of adding iron oxide to molten copper. This technology enables efficient recycling of copper scrap.
