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.PROCESSGOLD - Professional Process Mining Software,Process mining uses this data to visualize and analyze the actual end-to-end processes, with all variants and relevant key performance indicators.
