Ore processing – Waihi Gold
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 Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grindingThe gold is recovered from this solution by electrowinning, zinc precipitation or refining technology such as the Mintek Minataur process The eluted carbon may still contain various organic 48 2 4 4Au NaCN O H O NaAu CN NaOH+++ → + 22 2 The process design of gold leaching and carboninpulp circuitsThe process design of gold leaching and carboninpulp
