Energy and environmental implications of copper
网页1999年4月1日Mining operations that include the production of refined copper by hydrometallurgical processes (the most widely used technology is leaching–solvent extraction–electrowinning, L-S-E) require significant amounts of water, typically 2.5–3.0 m 3 /s per ton of refined Cu. Water recirculation (up to 85% in new projects) is thus a
