    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 diggersTo a casual observer, mining gold seems simple: find ore, extract it then process it into gold However, this isn’t the case since mining for gold is a more complex process which occurs in stages Before the precious metal can be extracted, firms are required to explore the area in order to accurately determine the size of the deposit and how the ore can be extractedAn Overview of the Five Stages of Gold Mining
