Beschreibung
Zusammenfassung:	The present invention provides methodes and composition for improving a froth flotation process for the removal of mineral values from aqueous solutions. The method uses mercaptide microemulsions to improve the separation effectiveness of a collector. The present invention provides a method of enhancing the performance of a collector in a froth flotation separation of mineral ore in a medium, the method comprising the steps of: forming a slurry by blending a collector microemulsion, the mineral ore in a medium, and optionally other additives, -and removing concentrate from the ore by sparging the slurry; wherein the collector microemulsion comprises a continuous phase which is an aqueous carrier fluid and a dispersed phase comprises a mercaptide.
