WO2007103151A2 Tribostatic separation system and method

A method for separating components of a material includes grinding (100) the material into gangue of predetermined particle size. The gangue is induced (200) with a tribostatic charge. Optionally, the tribostatic charge is induced while the gangue is in a chamber filled with inert gas. The particles of the gangue separate spatially (500) according to density and particles are extracted at a
