Abstract

A method for separating components of a material includes assaying the material to determine the components and the specific gravity of at least one component. The material is ground into a heterogeneous gangue of predetermined particle size. Optionally, the particle size is determined according to Stokes' law. The gangue is delivered to a fluidizing bed having a gas permeable floor and a gas source delivering gas through the gas permeable floor at a predetermined gas flow rate, optionally corresponding to the terminal velocity of a component to be separated from the gangue. The gangue separates according to specific gravity and particles are extracted at a predetermined distance from the fluidizing bed.
