  • Coal–oil assisted flotation for the gold recovery

    Selectivity for gold decreases for fine gold particles (−20 μm) because of the co-flotation of gangue components (Glembotski et al., 1974). Flotation of gold particles coarser than 200 μm is very difficult due to their high specific density, floating slower than finer particles and also requires more collector to recover by flotation ...

  • The Flotation of Alluvial Gold

    The air sparged hydrocyclone is effective at recovering fine gold from a fine Colarado River sand, but is not effective for the coarse and dense beach sands of New Zealand. The flotation column shows much promise for these sands, when recoveries of over 80 per cent and mass yields of less than one per cent can be achieved in a single pass.
