<p>A method and a system for recovering precious metals are provided to reduce operating cost in a process of recovering precious metals, suitably apply an automation process to a PCB(printed circuit board) plating process, and enable precious metals to be recovered at a high recovery ratio and effectively recovered even at a low concentration. A system for recovering precious metals comprises: an anode wire and a cathode wire connected to a power supply; a body in which one or more anodes and cathodes respectively connected to the anode wire and the cathode wire are alternately disposed, and a target recovery solution is filled, wherein the cathodes are made from a porous metal with a plurality of pores as a three-dimensional reticular structure and manufactured by uniformly inserting a foaming agent into the molten metal while rotating molten metal to a rotation speed of 10,000 rpm or more; and a circulation unit for circulating the recovery solution contained in the body.</p> |
