METAL REGENERATION METHOD AND METAL-POWDER-CONTAINING RESIN MOLDED BODY MANUFACTURING METHOD

WIPO Patent Application WO/2023/175677

A1

Provided is a metal regeneration method including a step (S10) for preparing a metal mixture in which multiple types of non-magnetic metal bodies having different shapes from each other are mixed and a step (S20) for pulverizing the metal mixture into metal powder. In the step (S20) for pulverizing, the particle diameters of the entire metal powder are reduced so as to be equal to or less than a first value; first metal powder having the particle diameters that are equal to or less than a second value is removed from the entire metal powder, the second value being less than the first value; and second metal powder having particle diameters that are greater than the second value and equal to or less than the first value is recovered. The above metal regeneration method additionally includes a step (S30) for removing, from the second metal powder, third metal powder having particle diameters that are equal to or greater than a third value and recovering fourth metal powder having particle diameters that are greater than the second value and less than the third value. The third value is greater than the second value and less than the first value.
