<p>A method for separating metal materials plated on injection-molded products is provided to separate the metal materials from synthetic resin by generating bubbles on the surface of the injection-molded product in fermenting fermentation solution deposited on the crushed injection-molded product. The method for separating metal materials(14) plated on injection-molded products comprises an injection-molded product fermentation step of precipitating the waste injection-molded products in a fermentation solution(112) and fermenting the injection-molded products for the predetermined time and a metal separating step comprising a first separating step of firstly separating the metal material from synthetic resin(11,12) by impact and a second separating step of completely separating the synthetic resin and the metal by using the specific gravity of water.</p> |
