FIELD: enrichment of useful minerals. SUBSTANCE: ground ore is treated by modifiers and is conditioned with sulfhydryl collecting agent. N,N-bis-(2-oxyethyl)-3-aminopropine-1 is added before said collecting agent being used, their mass ratio being 1;80-1:160. Then foaming agent is added. Sulfide minerals are flotated to isolate foamed product and tail fraction. Said tail fraction is treated by oxyhydryl collecting agent and scheelite is flotated to isolate tungsten minerals as foamed product. EFFECT: improves efficiency of the method. 1 dwg, 2 tbl
