Mumbai, Jan. 22 -- International Copper Study Group (ICSG) released preliminary data for November world copper supply and demand in its January 2026 Copper Bulletin. Preliminary data indicates that world copper mine production increased by about 1% over the first eleven months of 2025, with concentrate production increasing by 0.4% and solvent extraction-electrowinning (SX-EW) by 3.5 %. In 2025, global mine production benefited from additional output from projects ramping up to capacity and an improvement in production at a number of operating mines. However, lower grades and incidents at some major copper mines, including Kamoa (May) and Grasberg (September), significantly constrained global growth.
