ABSTRACT:
A fluidized, dry bed, ore concentrator in which a uniform air stream is utilized to fluidize ore particles within a region defined in part by two, moving, riffled surfaces. The particles are statically charged to enhance separation of particles within the fluidized mass. The less massive of the like-charged, fluidized particles are drawn off by a first riffled surface and denoted "tailings". The more massive, and valuable, of the particles are drawn off by the second of the two riffled surfaces and denoted as "fines".
