摘要： PROBLEM TO BE SOLVED: To provide a means for efficiently recovering platinum group elements by efficiently concentrating platinum group elements into a molten copper phase obtained from copper iron scrap (scrap containing both copper and iron) containing platinum group elements typified by platinum.
SOLUTION: The copper iron scrap containing the platinum group elements, is melted and a carbon source is caused to be contained in the obtained molten material, and thus, this molten material comprises two-liquid phases of a molten copper phase containing one or more kinds rare metals selected from the group composed of Nd, Pr and Dy and a molten iron phase containing carbon concentration of ≥1 mass%, and the molten copper phase is recovered by separating this two liquid phases, and the platinum melted in this molten copper phase is separated and recovered from the molten copper phase. The copper iron scrap may contain rare metal and a member containing the rare metal may be added into the molten material. Further, the total concentration of the rare metal contained in the molten copper phase, is desirable to be ≥1 mass%.
