FIELD: minerals concentration equipment, in particular, lump-by-lump separation of radioactive and non-radioactive ores.
SUBSTANCE: method involves feeding ore lumps into measurement zone; registering gamma-radiation and separating ore lumps into concentration products on the basis of signal value surpassing predetermined tuning threshold value, with registration of gamma-radiation being performed with exposure and tuning threshold selected individually for each ore lump; selecting exposure duration in proportion to length of ore lump; selecting tuning threshold for each ore lump equal to product of tuning threshold value for ore lump with average weight in class under sorting process multiplied by square of ratio of exposure duration for ore lump under measurement process to exposure duration for ore lump with average weight in size class under sorting process.
EFFECT: increased efficiency of separation process by optimizing conditions for measuring all of ore lumps regardless of their weight.
