Operations At A Copper Refinery And Smelter Facility As Peru Post Biggest Trade Surplus In Years

An employee stands in front of a machine moving copper anodes and cathodes during the electrolytic refining process at the Southern Copper Corp. refinery in Ilo, Peru, on Thursday, Jan. 26, 2017. Peru posted its biggest trade surplus in five years in December, as rising copper output and higher prices boosted exports. The South American country last year overtook China to became the world's biggest copper producer after Chile, allowing it to record its first annual trade surplus in three years.
