FIELD: technological processes; mining.
SUBSTANCE: method involves exciting irradiation of minerals, luminescence filtration, registration of filtered luminescent light flux part and useful component separation according to a given light flux value. Light flux registration is performed in the zone of spectral luminescence density minimum of separated minerals. During light flux filtration blue-green spectral zone within the range of 450-550 nm is separated, e.g. through a couple of SZS-3 and SS-20 filters or interference filter with maximum permeability at 520-530 nm.
EFFECT: increased process selectivity.
