The invention provides a regeneration treatment method for waste tinned copper pellets. The regeneration treatment method for the waste tinned copper pellets comprises the steps that the waste tinnedcopper pellets are added into a spiral feeder under a vacuum condition at first, the spiral feeder is heated, and the temperature in the spiral feeder is maintained and controlled to be 165-230 DEG C;then the waste tinned copper pellets are slowly fed into a collector by the spiral feeder, tin coatings and a small amount of copper on the surfaces of the waste tinned copper pellets are separated from the copper pellets to be powdery, and after being detinned, the copper pellets enter the collector together with the tin powder and copper powder separated from the copper pellets; the detinned copper pellets and copper-tin mixed powder are obtained in a screening mode; and then the copper-tin mixed powder is heated in an oil bath and screened for filtering, and copper powder and tin particlesare obtained in a separation mode. According to the regeneration treatment method for the waste tinned copper pellets, efficient mechanical separation of tin is achieved under the vacuum condition through the characteristic that tin cannot stand heat, the whole process is free of participation of any chemical reagent or chemical process, devices applied are simple, operation is convenient, and industrial application can be achieved.
