FIELD: technological processes.
SUBSTANCE: luminescence is excited by pulse X-rays, and luminescent light flux that originates from radiated material, which stays in the maximum range of diamond slow component radiation, is transformed into electric signals. Digitisation of obtained aggregate of luminescence intensity values is carried out. Then intensity values are calculated for slow and fast components of luminescence at the moment of pulse X-rays interruption. Separation criterion is calculated, which is equal to ratio of design intensity values of slow and fast components of luminescence. If separation criterion stays in the range preset by threshold values, signal is sent to actuating mechanism for separation of useful material into concentrate sump.
EFFECT: higher selectivity of separation process and extraction of valuable component by application of differences in kinetics of separated materials X-ray luminescence.
