Australia’s gold mines by production, grades and costs ...

22/05/2019  Scale, grades, processing costs, open pit vs underground. The interesting aspect of the AISC metric is the number of factors that feed into the final figure, and similar to any other sector costs, they can vary from month to month and year to year. In the case of gold stocks, better grades usually translate into lower cost mines. Open cut mines are normally cheaper to operate than underground ...

Open-pit mining - Wikipedia

Typical open cut grades. Gold is generally extracted in open-pit mines at 1 to 5 ppm (parts per million) but in certain cases, 0.75 ppm gold is economical. This was achieved by bulk heap leaching at the Peak Hill mine in western New South Wales, near Dubbo, Australia.. Nickel, generally as laterite, is extracted via open-pit down to 0.2%. Copper can be extracted at grades as low as 0.11% to 0.2%.

Open-Pit Mining Methods

Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit ...
