Key Stages In the Mining Process | Cornish Mining World Heritage Site

From finding the right location to dressing and smelting the ore, there was much more to mining than just what happened underground. The mining process was complex, with several stages. So what came first and how did it all work? There were six main stages in the Cornish mining process: 1. Prospecting/Surveying...

The Mining Process – Waihi Gold

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. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the...
