- Copper Mining Water Consumption
This means copper miners must find alternative water supplies and make better use of each liter of water consumed. And with many mines designed when less consideration was given to water scarcity, retrospective changes are necessary. "There are several motivators to reduce water consumption," says Yacoub. "The first is water stewardship.

production of 220 million pounds of copper. This gives 7.4 gallons of water/pound of copper, which is at the low end. The decrease in water usage by mines is better illustrated by exploring the data from specific mines. The Morenci Mine was the second largest open-pit copper mine in North America in 2009, and one of the largest in the world.
