Gold Fields will invest $ 7mn to improve its copper processing operations in Cerro Corona mine, Cajamarca, Peru. The investment will be used to improve the crushing process and pebbles circuit as well as the storage and shipment of ore concentrate at the Salaberry Port.
The South African miner also received the National Service of Environmental Certification of Peru’s approval, to begin the optimization processes at its facilities in Cajamarca on Tuesday. Part of this process will include replacing the primary sizer-type crushers with similar ones, but with a greater capacity to directly process the mineral even if the ore is harder.
The Cerro Corona mine, which began operating in 2008, is expected to produce around 407,000mt of copper concentrate in its 15-year life expectancy. Its Metallurgical Process Plant has a processing capacity of 18,000mt per day.
