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 grinding (SAG) mill (4) along with water and steel balls. Gold production declined and many gold mines closed during World War I (1914-1918) due to a shortage of manpower, decreasing ore reserves, and increasing costs.
