<p>PROBLEM TO BE SOLVED: To surely prevent iron from the iron part of a iron core etc., from mixing into copper and to recover the copper part in high cleanliness and high purity from scrap of a motor and a transformer, etc., containing the iron core, etc., in a recycling method of copper from the scrap of the mixture of the iron part and the copper part. SOLUTION: The scraps 1, 2 of the mixture of the iron part and the copper part are arranged in the inner part of an induction heating coil 3, and only the iron part as magnetic body is induction-heated by energizing this induction heating coil and the copper part is made into semi-melting or melting state with this heat to remove the iron part remaining in the solid state. The recycling method of copper from the scrap is profitable to the recover of copper from the coil wound with a copper wire around the iron core.</p> |
