In recycling copper scrap, the removal of impurity elements is a critical subject for ensuring product quality. Lead and nickel which have been problematic to remove by conventional dry refining have been successfully removed, simultaneously, by the very simple method of adding Fe2O3 to molten copper. This technology enables the recycling of copper scrap by dry refining.
