how does a water flotation mill work for gold

  • Ore processingWaihi Gold

    The barren slurry now known as tailings is pumped to the tailings storage facility (5). In contrast by the time the carbon reaches the first adsorption tank it has recovered most of the gold and silver from solution. This loaded carbon is then pumped to the elution circuit (6) where the gold and silver is washed off with superheated water.

    Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite coal is naturally hydrophobic.
