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

The process of smelting separates the metal from the mineral by heating the mineral in the presence of a material known as a flux. The desired mineral settles to the bottom of the melt and can be separated out. The (unwanted) material at the top of the melt can harden into slag. The smelter is often in a different location than the mine.
