A method and a device for recovering hydrogen pulverized powder of a raw-material alloy for rare-earth magnets capable of lowering the possibility that hydrogen pulverized powder remains in a recovery chamber; therefore, enhancing magnetic properties by reducing an oxygen content of an obtained rare-earth magnet. A processing container 50 is carried into a recovery chamber 40 from a processing chamber after inert gas is introduced into the recovery chamber 40. The raw-material alloy for rare-earth magnets in the processing container 50 is discharged into the recovery chamber 40 after the pressure in the recovery chamber 40 is reduced Thereafter, inert gas is introduced into the recovery chamber 40, and the raw-material alloy for rare-earth magnets is recovered into the recovery container 50 after a pressure in the recovery chamber 40 is set to a predetermined pressure by inert gas.
