Quellaveco. Construction of Anglo American's copper project in Peru started in 2018, with the fouryear development culminating in its commissioning earlier this month. At full capacity, Quellaveco expects to deliver 300,000 tonnes of copper annually. The capex divided by 300,000t amounts to a capital intensity of 18,333.

History Miners at the Tamarack mine in Copper Country, in 1905. The Old Copper Complex in North America has been radiometrically dated to 9500 BP—, about 7480 BCE—making it one of the oldest known examples of copper extraction in the world. The earliest evidence of the coldhammering of native copper comes from the excavation at Çayönü Tepesi in eastern Anatolia, which dates between ...

The dose rates of an underground copperzinc mine and the radioactivities of collected samples were measured using a surveymeter and a gammaray spectrometer. There was no significant difference found between mine dose rates and background radiation in the region. The average activity concentrations of 226Ra, 232Th, and 40K in tailing samples were found to be 27%, 83%, and 71% higher than in ...
