All of this means that productivity, as measured in tons produced per worker per shift, can be 5 to 50 times lower, depending on the mining technique, than on the surface Balanced against this is the fact that underground only ore is mined, whereas in the open pit there are often several tons of waste stripped for each ton of oreOpenpit 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 openpit mining The removal of this material is known as stripping The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pitOpenPit Mining Methods

Measuring labor productivity in the gold mining industry
Measuring labor productivity in the gold mining industry By Adam Webb | 31 March 2017 Labor productivity in the mining industry is often expressed as tonnes of ore mined per man hour and, as a consequence, open pit mines are often described as being more productive than underground minesTypical open cut grades Gold is generally extracted in openpit mines at 1 to 5 ppm (parts per million) but in certain cases, 075 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 openpit down to 02% Copper can be extracted at grades as low as 011% to 02%Openpit mining Wikipedia
