Chile Mining Industry Reduces Freshwater Usage


Continental water use by the mining industry in Chile fell 6.8% in 2019 to 12.45 cubic metres per second compared with 2018, according to state copper agency Cochilco in its annual water report. Cochilco said part of the fall was due to a 1% reduction in the quantity of mineral processed as well as miners moving to use more seawater and to recirculate water more. The agency said seawater use increased by 1.7% to 4.06cu.m/s and recirculated water by 15% to 53.32cu.m/s, with a national recirculation rate of 76% compared with 73% in 2018.
