| Abstract: | A new approach for the removal of copper from solid ferrous scrap is described. With this proposal, solid ferrous scrap intermingled with copper is brought into contact with molten aluminium, which preferentially dissolves copper. After a duration of 5 to 10 minutes at a temperature of 1018 ± 5 K, steel scrap is removed from the bath, resulting in being free of copper contamination. The present method offers the advantage of far lower costs than any other processes ever suggested for copper removal. |
