Abstract

A method and apparatus for sorting a mixture of particles containing a first group of particles of substantially uniform size and density and a second group of particles of substantially the same size as the particles of the first group and of different density than the particles of the first group. The noted mixture is supplied to a reservoir in which it is fluidized so that the particles gather into different levels in accordance with their density. The particles are then removed from the reservoir at their different levels.
