Abstract RU 2270725 C1

FIELD: mining; mineral dressing.

SUBSTANCE: the invention is pertaining to the field of mining, to mineral dressing, in particular, to the composition for flotation of minerals and may be used at floatation of the ores of the nonferrous metals, precious metals and black coal. The invention allows to increase the level of extraction of the target components. The composition includes a foam maker based on isoalkenylacetylene alcohols and the collector. The used foamer is based on the isoalkenylacetylene alcohols C9-C10 of the general formula RCH=CR'C≡CC(CH2R ")(CH3)OH and having the following structure (in mass %): isoalkenylacetylene alcohol C9-C10 of the general formula RCH=CR'C≡CC(CH2R")(CH3)OH: 80.0-99.0 %, diisoalkenylacetylenes C9-C10 of thegeneral formula RCH=CR'C≡CC (CH2R")=CHR"': 0-20.0 %, α-acethylene tertiary γ-diols C9-C10 of the general formula(RCH2)(CH3)C(OH)C≡C(CH2R")(CH3)OH: 0-5.0 %, where R=H, CH3; R'=CH3, C2Н5; R"=H, CH3; R'"=H, CH3, an inhibitor of the radical polymerization: 0-1.0 %.

EFFECT: the invention ensures an increased level of extraction of the target product.
