    Flotation of Gold and Gold-Bearing Ores ScienceDirect

    01-01-2016· The first detailed laboratory study of the influence of sodium sulfide on the flotation of gold-bearing ores was undertaken in the mid-1930s (Leaver and Woolf, 1935). The outcome from this study was that, in general, sodium sulfide retards the flotation of gold, although for some ores there was benefit in its addition.

    Froth Flotation Method JXSC Machine

    This froth flotation method is used to treat quartz sulfide ores or gold-silver-bearing pyrite and pyrrhotite containing gold telluride, pyrrhotite, chalcopyrite and other sulfide minerals.

    Flotation Froth an overview ScienceDirect Topics

    Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig. 17). A chemical reagent, called a frother, is normally added to promote the formation of small bubbles.
