A particle separator and a method for sorting particles or matter from a particulate mixture discharged thereon is described. It comprises an endless belt conveyor having an outer surface provided with a plurality of longitudinally extending parallel endless sorting channels formed therein. The endless belt is driven and displaced in a longitudinal direction under a supply bin which discharges the particulate mixture in an upper region thereof. The channels have a predetermined width/depth ratio and are configured to receive and retain therein unwanted matter of a size capable of being received in the channels. An adjustable support frame adjustably positions the endless belt conveyor at a desired inclined transverse angle above a support surface. The particulate matter is discharged in an upper region thereof at a receiving end and gravitates transversely of the longitudinal direction of displacement of the endless belt towards a lowermost part of the endless belt where it is discharged and conveyed. A substantial portion of the unwanted matter is trapped in the channels during this gravitational displacement of the particulate mixture, and discharged at a discharge end of the conveyor whereby to remove a substantial part of this unwanted matter from the particulate mixture.
