There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling. Open pit mining is

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. This process removes 93% of the gold and
