Particles (24) of ore, e.g. having a radio-active component, are sorted by feeding the particles in a stream on a conveyor (12) past one or more detectors (14) to detect a specific ore characteristic in the particles and deflecting either the particles detected to include the characteristic above a predetermined level or the particles which do not include the characteristic or the particles which include the characteristic below the predetermined level from the stream by means of a fluid jet from a fluidically operated valve (18). <IMAGE> |
