Abstract, A process and apparatus wherein a sizeclassified bed of particles is fluidized by agitating a supporting surface (50) with a gyratory motion to fluidize the particle bed. Particles are contacted with surfaces, e.g. vertically projecting surfaces (51) (62) (66) (68), movable with the supporting surface and defining two or more annular regions so as to impart sufficient fluidity to allow the particles to move within the particle bed and distribute themselves according to their relative densities. Particles are then permitted to move through openings (52) (70) (72) between these annular regions whereby the more dense particles tend to accumulate in one of the annular regions and …
