The Various Stages In The Process Of Mining Gold

  • Gold extraction - Wikipedia

    Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.

    A sodium cyanide process is used to extract the gold from the ore, and various other processing techniques are used to produce 99.9% pure gold bullion from the ore. The results of the feasibility study show that the ore can be processed by agitation leaching, which is preferred over heap leaching due to the low recovery associated with the heap leaching technology. The problem is to find the

  • 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.
