Mining and Water Quality USGS

Although a water-treatment plant at Iron Mountain has reduced the amount of copper and zinc leaching from Iron Mountain by 80 to 90 percent since 1994, some acid waters from the mine site still make their way to Spring Creek, a tributary to the Sacramento

Water Consumption at Copper Mines in Arizona

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.

Water management for copper mining ScienceDirect

Jul 01, 2012 Effective water management is critical in any mining operation, so finding innovative mine dewatering and fluid transfer applications is essential for today's mineral extraction processes. Petar Ostojic discusses how custom engineered barge pump systems help accomplish this task in two copper mining companies.

Lessons From the Most Toxic Open Pit Copper Mine in the World

Nov 28, 2016 Except for canaries, underground mines have never been a threat to birds, and underground mines were the norm until the 1950s when open pit mining began in Montana. The Berkeley Pit was the first open pit mine in the area and today it is the most toxic open pit copper mine in the world. And it is lethal to water birds.
