Chile’s Escondida, the world’s biggest copper mine, said on Monday that it will invest $180-million to revamp an older concentrator plant with processing capacity of some 100 000 t/d.
Escondida has three concentrators, and once all of them are up and running, the mine expects to produce around 1.2-million tonnes of copper annually for the next decade. The mine, nestled high in Chile’s arid Atacama desert, produced 1.15-million tonnes in 2015.
