To regenerate a metallic material and a resin material having high purity by adsorbing/separating the resin powder with metal coating film from the crushed mixed powder while dividing to several stages and certainly separating the resin powder with the metal coating film from a metal coating film powder or a resin powder.

The metal coating film resin material p deposited with the metal coating film is crushed to prepare the mixed powder m of the metal coating film powder a, the resin powder b with the metal coating film and the resin powder c and the mixed powder m is separated into the resin powder c and the resin powder b with the metal coating film and the metal coating film powder a using magnetic force while conveying the mixed powder m. Further, the resin powder c having low metal content is separated/recovered using the magnetic force while these separated resin powder c and the resin powder b with the metal coating film are conveyed.
