ABSTRACT:
A process and an apparatus for purifying a stream of mechanically comminuted material as well as for enriching fine ores and other minerals uses mechanical sorting. The thickness of the material stream is enlarged by shaking and an upper and a lower layer containing bigger or lighter and smaller or heavier particles, respectively, form due to the effect of gravity on the material stream. The layers are separated by the edge of a tube, whereupon the upper layer leaves the apparatus through the tube. A preferably exchangeable or liftable and lowerable disc deflects the path of the lower layer of the material stream in a meander-like or winding manner to controllably brake the speed of that material stream.
