The Mining Process Waihi Gold

The Mining Process. 1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately.

Large track mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore dressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 metres (3,300 feet) below the surface, and tunnels are extended to the ore body.
