SANTIAGO, Jan 7 (Reuters) - Chile state miner Codelco and BHP's sprawling Escondida mine saw copper output fall in November, according to Chile state copper agency Cochilco, amid a tubulent month of riots and mass protests that left much of the South American nation in chaos.
Cochilco said output at Codelco, the world's top copper miner, plummeted 11% in November over the same month in 2018, to 155,200 tonnes.
Production at BHP's Escondida, the globe's largest copper mine, fell 1.5% to 103,200 tonnes.
The Collahuasi copper mine in northern Chile, a joint-venture between Anglo American and Glencore , produced 56,700 tonnes in November, up 9.7%, the agency said.
Chile is the world's top copper producer. (Reporting by Dave Sherwood and Fabian Cambero; Editing by Steve Orlofsky)
