Abstract
A mixture of particles of different materials is further comminuted by rubbing contact while moving at high relative velocity along a surface of a solid body to a substantially smaller size range during which the particles of different materials acquire a very high differential charge, and while bearing such high differential charge the particles of different material are entered into an electric field for efficient separation of particles of one material from particles of another material.
