FIELD: enrichment of mineral resources. SUBSTANCE: magnetic fraction in the form metal filings in proportion 0.005-0.07 of starting material is added into treated gold-laden material before processing. Then mixture is processed 1-3 times in disintegrators of rotor type. In this case gold is imparted with magnetic properties. This makes it possible to conduct following magnetic separation. EFFECT: enhanced efficiency of gold ore beneficiation. 1 tbl
