Description	{{The Escondida copper-gold-silver mine produces more copper than any other mine in the world (1.483 million tons in 2007), amounting to 9.5% of world output and making it a major part of the Chilean economy. The mine is located 170 kilometers (110 miles) southeast of Chile’s port city of Antofagasta, in the hyper-arid northern Atacama Desert at an elevation of 3,050 meter (10,010 feet) above sea level. This astronaut photograph features a large impoundment area (image center) containing light tan and gray waste materials (“spoil”) from of the Escondida mine complex. The copper-bearing waste, which is a large proportion of the material excavated from open pit excavations to the north (not shown), is poured into the impoundment area as a liquid (green region at image center), and dries to the lighter-toned spoil seen in the image. The spoil is held behind a retaining dam, just more than 1 kilometer (0.6 miles) long, visible as a straight line at image lower left.}}
