Ore processing – Waihi Gold

2021-11-12  The slurry (1) of ground ore and lime moves into a series of six leach tanks (2) where a sodium cyanide solution is added. The tanks provide sufficient retention time to allow the gold and silver to be dissolved by the cyanide solution. Oxygen is added to assist in this process. The slurry then moves through a series of carbon adsorption tanks (3).
