Ore processing Waihi Gold

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. This 'loaded' carbon is then pumped to the elution circuit (6) where the gold and silver is washed off with
