  • Chlorine leach process - Falconbridge Nickel Mines Limited

    1975-04-29· After dissolution of all the metals except gold, the continued addition of chlorine to the leach slurry causes an abrupt rise in potential until gold starts to dissolve, after which sufficient additional chlorine is fed to the slurry to dissolve most of the gold. Thus substantially all the metals in the ore are leached and are present together in the same leach liquor from which they must be ...

  • Technologies | EnviroLeach Technologies Inc.

    Conventional gold mining operations rely heavily on cyanide leaching as the predominant method for recovering gold from ores and concentrates. Cyanide has been the leach reagent of choice in gold mining because of its high gold recoveries, robustness and relatively low cost. As a result, over 76% of all gold extracted worldwide is produced by hydrometallurgical extraction with the use of cyanide.
