The invention relates to a method of recovering metals in circuit boards in a classified manner, in particular to a method of recovering copper, tin, nickel, palladium, gold, silver and resin in PCBs.The method successively comprises the following steps: crushing the circuit boards into fine fragments through process flows such as crushing, acid leaching, anode rotating rattling electrolysis andflotation; then acid-leaching the fine fragments to dissolve active metal tin or nickel; then placing insoluble substances in an anode rotating rattling electrolytic cell to be electrolyzed to recovercopper; then filtering the mixture to obtain an anode filter residue, transferring the anode filter residue to water or heavy oil to be floated, wherein noble metals are settled and resin drifts on the surface by means of density variation of the metals, resin and a solvent, and recovering resin powder in the upper layer; and finally, further separating the noble metals by means of smelting. Themethod provided by the invention is an environment-friendly process which can separate and recover various metals and resins from waste circuit boards, so that all resources in the circuit boards arerecovered.
