Zusammenfassung:FIELD: chemistry. ^ SUBSTANCE: method comprises the extraction of molybdenum in sulphide form from water multicomponent solutions by the way of sodium sulphide loading to original solution, subsequent solution treatment with sulphuric acid up to pH = 2.5-3 and precipitation of molybdenum sulphide. beforehand sodium benzoate is added to original solution, its mole ratio to molybdenum salt is not less than 1:1. Sodium sulphide consumption must be not more than 100% of amount stoichiometrically necessary for molybdenum trisulphide precipitation. ^ EFFECT: decreasing of consumption. ^ 2 cl, 1 tbl, 1 ex
