FIELD: chemistry.
SUBSTANCE: method of froth flotation for extracting at least one precious mineral from the mineral ore body, which comprises: adding an enriching amount of collector at least at one stage of froth flotation process. The collector comprises primary or secondary organic ammonium salt of the organic sulfur-containing acid, selected from the group consisting of hydrocarbyl dithiophosphoric acids, hydrocarbyl monothiophosphoric acids, mercaptobenzothiazoles, hydrocarbyl xanthogenic acids, hydrocarbyl thioglycolic acids and hydrocarbyl trithiocarbonic acids. The collector comprising primary or secondary organic ammonium salt of C1-C5 hydrocarbyl dithiocarbamic acid is used using one of the versions of method implementation.
EFFECT: increased efficiency of the flotation extraction of precious minerals, reduced hazardous exposure on personnel and environment.
