Mining is the extraction of ore from the ground through either open pit mining or underground mining Companies generally prefer open pit mining if the deposits are closer to the surface and spread across a large distance Open pit mines are less capex intensive and help companies achieve lower unit costs by deploying large equipment economies of scale allowing companies to operate in low

The nature of the ore deposit determines the mining and mineral processing techniques applied Oxide ore deposits are frequently of such low grade 3 to 10 parts per million that extensive mineral processing cannot economically be justified In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation see below These heaps can be

The technology of extraction is expensive primarily because the process always requires gold mining companies to manipulate large physical quantities of ore for small results The energy required to heave grind and process ore is itself valuable as are the chemicals used in the process and this places a lower limit on the quality of ore which can be profitably worked in the gold mining
