FIELD: concentration of minerals. SUBSTANCE: initial raw is conditioned preliminary with collector-frothing agent following by separation and isolation of fuel mass to the foam product. The source of collector-frothing agent: fraction of reused aliphatic alcohols from dialkylphthalate production by esterification of aliphatic alcohols with phthalic anhydride in the presence of catalyst. EFFECT: improved method of coal flotation. 1 tbl
