FIELD: mining industry; concentration. ^ SUBSTANCE: invention relates to concentration of materials containing minerals luminescent under action of radiation. Proposed device contains transport mechanism, impulse excitation source, photodetector installed from side of incident X-radiation or from side opposite to incident X-radiation luminescent intensity signals processing unit, and instruction generation unit with actuating mechanism. It is furnished with unit for calculating ratio of luminescence components made in form of programmable controller. Luminescence signals processing unit is made in form of analog-to-digital converter. Output of impulse excitation source is connected with first input of programmable controller and with second input of analog-to-digital converter. Output of photodetector is connected with first input of A/D converter whose output is connected with second input of programmable controller whose output is connected with input of instruction generation unit of actuating mechanism. ^ EFFECT: increased selectivity of separation process owing to use of differences in kinetics of roentgen luminescence of separated materials. ^ 1 dwg
