PROBLEM TO BE SOLVED: To provide a method for recovering metals from electronic or electric parts with resins, by which highly concentrated metal-concentrates and highly concentrated resin-concentrates can be sorted, and by which valuable metals such as gold, silver, copper and palladium can be efficiently recovered from the electronic or electric parts with the resins such as printed boards. SOLUTION: The electronic and electric parts with the resins are crushed into crushed materials A and dust B by a crusher, and the crushed materials A are separated into magnetic materials C and non-magnetic materials D by a magnetic sorter. The non-magnetic materials D are sorted into the metal- concentrated M, O, Q and the resin-concentrates N, P, R by a jigging sorter. |
