1. A froth flotation process for recovering at least one value mineral from a mineral ore body, the process comprising:
adding a beneficiating amount of a collector to at least one stage of a froth flotation process, wherein the collector comprises a primary or secondary organic ammonium salt of an organic sulfur-containing acid selected from the group consisting of hydrocarbyl dithiophosphoric acids, hydrocarbyl monothiophosphoric acids, mercaptobenzothiazoles, hydrocarbyl xanthic acids, hydrocarbyl thioglycolic acids and hydrocarbyl trithiocarbonic acids.
