  • The Mining Process – Waihi Gold

    A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

  • AARL Carbon Stripping System Operation: Elution ...

    During this stage a 2% caustic/3% cyanide solution mixture is re-circulated through the loaded carbon in the elution column until such time as a predetermined "top of column" temperature is reached. By this time most of the gold and silver on the carbon will have been desorbed into solution and both the carbon and the solution will have reached an optimum temperature for the subsequent ...

  • Carbon Stripping – Denver Mineral Engineers

    carbon as a sodium or calcium/gold cyanide ion pair (2) is desorbed from the carbon by a reversal of the adsorption kinetics. Gold is recovered from the pregnant strip solution by electrowinning onto steel wool. The gold depleted solution is then reheated and recycled to the carbon bed for reuse (see Figure 1).
