Global copper mine output shrinks 2.4% in first 11 months of 2017: ICSG

摘要

World mine production declined an estimated 2.4% in the first 11 months of 2017, with concentrate production declining 2% and solvent extraction-electrowinning (SX-EW), 3.5%. The decline in world mine production owed to: a 1.6% decline in production in Chile, the world's biggest copper-mine producing country, which was negatively affected by the strike at the Escon-dida mine and lower output from Codelco mines; lower concentrate production in Argentina, Canada and Mongolia of 57%, 15.5% and 15%, mainly from lower grades in planned mining sequencing and Argentina's Alumbrera mine approaching end-of-life; a 14.5% decline in Indonesian concentrate production, with output constrained by a temporary ban on concentrate exports that started in January and ended in April; and a 12% decline in U.S. production owing to lower ore grades, mining rates and unfavourable weather conditions at the start of the year.
