Abstract
In an electrostatic separator or a magnetic separator, prior to electrically charging or magnetization of particles in order to carry out separation of mixed powder of particles having different properties from each other, classification is performed by a classifier so that the content of fine powder having a spherical equivalent diameter of 10 μm or smaller is 15 mass % or less. After the classification, prior to electrostatic separation or magnetic separation, an operation of dispersing the mixed powder of particles may be carried out.
