[0004] In recent years, the functions of automobiles have become more and more advanced, and the types and number of electronic devices mounted thereon have increased, and accordingly, the number of wire harnesses has also increased. Since the wire harness is stretched around the entire body and is difficult to remove, the wire harness was often crushed together with the body and the like and shredded with a shredder. However, wire harnesses generally have multiple wires, terminals, connectors,
It is composed of tapes that bind electric wires, and when this is crushed together with the car body and shredded with a shredder, non-ferrous metals such as electric wire conductors and terminals are mixed with the car body iron, and high-quality scrap iron is collected. Becomes difficult. In order to recover high-quality scrap iron, non-ferrous materials, especially non-ferrous metals such as copper and copper alloys used in wire harnesses, should be removed as much as possible before the crushing process. It is valid. Therefore, the removal of the wire harness has been performed at the stage before the crushing process. However, as the next stage, the removed wire harness needs to be processed. As shown in FIG. 3, as shown in FIG. 3, a wire harness is processed separately from a crushed vehicle body or the like, crushed using a shredder, and copper and copper alloy used as conductors and terminals, and other resin, etc. (dust)
And it has been done to separate.

Conventionally, it has been considered to obtain high-purity copper and further to use it as a material for electric wires. However, terminals and the like incorporated in the wire harness usually contain zinc or nickel. If they contain zinc or nickel, they are not easy to remove in furnaces that make conductors,
Even if nugget copper is recovered, it cannot be simply reused as a raw material for a conductor.
