FIELD: mining industry. ^ SUBSTANCE: invention relates to technology of flotation processing of sodium-containing mineral stock, e.g. carnallite ores and capping salts from salt lakes. Collecting reagent employed is mixture of alkylmorpholines and glycol ester taken in ratio 1:(0.05-0.35), respectively, glycol ether, in particular, being 2,2,4-trimethylpentane-1,3-diol monoisobutyrate, 2,2,4-trimethylpentane-1-ol isobutyrate, 2,2,4-trimethylpentane-1,3-diol monoisobutyrate. Flotation feed contact with collector is accomplished in suspension with content of solids 35-55%. ^ EFFECT: reduced consumption of expensive collector and lowered content thereof in chamber product of halite flotation. ^ 3 cl, 4 tbl, 5 ex |
