In accordance with the present invention, there is provided a method of improving the separation of mineral values from their associated gangue. The method itself involves the addition of an effective amount of a treatment reagent to the froth flotation process which enhances the ore recovery. The treatment reagents of the method of the present invention comprise water-soluble organophosphonates which when added to the flotation feed slurry enhance the recovery of ore values therefrom. The organophosphonate treatment reagent may be used alone or in combination with a polymeric dispersant. |
