Question

method of separating copper powder and steel powder

Answer 1

Answer:

A method of separating a powder mixture is disclosed. A first magnetic field is applied to the powder mixture which may contains a non-magnetic metal powder and a contaminant powder. A field strength of the first magnetic field magnetizes the non-magnetic metal powder and leaves the contaminant powder non-magnetized. A second magnetic field is applied to the powder mixture to separate the magnetized metal powder from the non-magnetized contaminant powder.
