Copper output slumped at Chile’s state miner Codelco and BHP’s sprawling Escondida mine in November, according to Chile state copper agency Cochilco, amid a turbulent month of riots and mass protests that rocked the mineral-rich South American nation.
Cochilco said output at Codelco, the world’s largest copper miner, plummeted 11% in November over the same month in 2018 to 155 200 t. Production at BHP’s Escondida, the globe’s largest copper mine, fell 1.5% to 103 200 t.
