The invention relates to a waste circuit board metal recovering method and a recovering device based on the high frequency induction heating principle. The recovering method comprises the steps that a crucible is driven to rotate by an electric motor; an induction coil is electrified, the waste circuit board fragment metal in the crucible is heated under the action of electromagnetic induction, the metal under a rotation state clings to the inner wall of the crucible, and the metal shows a molten state after achieving a melting point; the metal under centrifugal force enters a cavity between the crucible and another crucible, then flows into a material collection bottle along the inner wall of the cavity, and finally is cooled by a device.
