Abstract
Processes by which a mixture of two or more discrete particulate materials, each of the materials having a different sliding coefficient of friction, can be separated using methods which take advantage of velocity differences generated by application of a force to the mixture over a surface as a function of its sliding coefficient of friction. In a first embodiment, the mixture is fed by a supply means (116, 118, 120) to the surface of a rotating disc (122), whereby the materials will be induced to move by centrifugal action. A second embodiment employs a surface (230) inclined to the horizontal and vibrated, causing materials of different coefficients of friction traverse the surface (230) along separate paths. A third disclosed embodiment uses an inclined slide (316) to provide separate momentum effected paths to the materials.
