Abstract
The invention concerns a method of sorting diamond-containing particles online from gangue particles. In the method, the particles (12) are subjected to irradiation by an X-ray or thermal neutron beam (20) from a source (18). A detector (22), arranged at a predetermined orientation to the incident beam (20), detects radiation which is elastically scattered by each particle. A diffraction spot pattern is then derived from the detected radiation and is compared, by a computer (24), with a diffraction spot pattern for diamond. A determination is made whether there is correlation between the patterns which is indicative of the presence, in the particle, of diamond. When such correlation exists, the relevant particles are separated from the other particle s.
