    These were loed in the gold mining areas where the slimes dams were retreated mainly to produce a concentrate for sulphuric acid production. The gold content was /ton of which about 50% was recovered in the concentrate. Early work in the flotation group focused on a wide range of problems associated with these flotation plants.

    Gold Flotation Circuit. Froth flotation is a physicochemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and appliion was developed for graphite by the Bessel brothers (1877).

    Elemental gold has a specific gravity of, and typical ore has a specific gravity of about All gravity concentration devices create movement between the gold and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material. The prospector's gold pan is the most familiar gravity concentration device.

    Nov 01, 2011 · "Flotation reagent selection is paramount and test work is necessary to ensure the optimum reagent suite is utilised. If the ore contains a low amount of iron sulphides, xanthate collectors are often suitable to float copper sulphideminerals. If native gold is present, dithiophosphates can be used which are less selective to iron sulphides.
