1. The United States Montana, Butte City, Berkeley open-pit mine
Butte City, Montana, United States Berkeley open-pit mine
This was originally a copper mine, from 1955 to 1982 before mining, and later also found gold and silver. A well-designed drainage system, making the local water level is low, suitable for mining. Today, the depth of 1780 feet (about 540 meters) in Berkeley open pit filled with 900 feet (270 meters) of water, which mixed with metals and arsenic, cadmium, copper, zinc, pyrite, sulfuric acid and other chemicals. Acidic waste water with battery electrolyte (battery acid) is almost, you can directly from "exploitation" of copper. At present, the Berkeley open pit mine has been the U.S. federal government as a "Super Fund" (Superfund) hazardous material disposal sites, because it may pollute surrounding groundwater. Surprisingly, there turned out to be a tourist destination, there are gift shops, ticket for two dollars. This photo is August 2, 2006 by the International Space Station astronauts shot.
2. Chile's Escondida copper mine
Chile's Escondida copper mine
Escondida copper mine (Escondida mine) is located in northern Chile's Atacama Desert, began mining in 1990, annual output of copper in the world in the first place. 2007 annual output of 1.5 million tons of copper, valued at more than 100 billion U.S. dollars, accounting for nearly one-tenth of the world's copper production. Escondida copper mine workers in the total number of more than 6,000. This photo is a 2000 NASA's Terra satellite by the United States Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) captured.
3. Utah Copper pit Bin Han
Bin Han pit copper mine, Utah, United States
Bin Han copper in the United States Salt Lake City suburb 20 miles (about 32 km), Office of the Ochil Hills (Oquirrh Mountains), from the mining of copper production has more than 18 million tons, second to none in the world. The Copper 2.75 miles wide (about 4.4 kilometers) deep 4,000 feet (approximately 1.2 km), even if the Empire State Building will be two stacked together, would not have reached the Peak. By 2015, Bin Han copper will reach the depth of 4500 feet (approximately 1.37 kilometers), then, they can put down one of the Empire State Building. Copper within the mesa may be 80 feet (about 24 meters) high, on the one hand be used as a base for mining equipment, on the other layers of slope stability. Bin Han copper mining began in 1904, also named as historic sites by the United States. This photo from the International Space Station astronauts used a digital camera on September 20, 2007.
4. The United States, California, Yuba River gold mine
Yuba River Gold Mine, California, USA
Yuba River gold mining activities reached a peak in recent years, workers use high-pressure water jet in the upper reaches of the Sierra Nevada mining, dredging from the Yuba River, in the residue of the gravel to find gold, and later, resulting in such a red-brown and gray hills, and hills of water fills the valley between the strange landscape. In 1848, gold was found in the Sierra Nevada shortly after the panning technique (panning) will give devastating hydraulic mining. In the hydraulic mining, workers use high-pressure jet of water treatment sludge. In the gold extracted from the gravel after the gravel would be thrown away, cis-river into the Sacramento River. Yuba River was eventually injected into 685 million cubic feet of mining waste, which makes the water level increased from river overflows, flooding the farmland.
Yuba River dredging work began in 1893, shortly after the mining companies began filtering and re-screening residue, extracted from a smaller gold particles. In 1970, all the easy gold mining have all been adopted finished, and then is the production of cement, gravel mining. Today, the Yuba River surrounding the ownership of land dispersed in mining companies, private and government hands.

5. Toquepala Peru Copper
Peru toquepala Copper
Toquepala copper mine is located in the southern Peruvian Andes, a wide 1.5-mile (about 2.4 kilometers), 2300 feet deep (about 700 meters). The main minerals are copper mine, but also found a gold, silver, molybdenum and so on. From the figure we can see that the construction is used to transport ore 60 miles (about 96 kilometers) outside the coastal railway meandering through the left side of the map of the Central Valley, south-west extension. This photo of the astronauts on the International Space Station in September 22, 2003 shooting.
6. Furuibote copper mine in Indonesia
Indonesia Furuibote Copper
Furuibote Mine (Freeport Mine) also known as格拉斯博格copper (Grasberg complex), is located in Indonesia, Sudirman mountains a large mine. Here, copper was first discovered in 1936, gold was in 1988. Today, Furuibote mine is the world's largest gold and copper one. The open-pit width of 2.5 miles (4 km), the region, there is a large-scale underground mining activities. Can see the glacier from the photo. This photo of the astronauts on the International Space Station in June 25, 2005 shooting.
7. Kananie Mine, Mexico
Mexico Kanania Mine
Kanania mine (Cananea mine) in the United States border with Mexico south of Sonora, 25 miles (approximately 40 km) Branch. Photo at the top of the right side of Kaluolada mine (Colorada Pit) wide and 1.6 miles (2.5 km). It is the world's largest copper producer, but also gold mining. The two layers of metal are usually flock to the bedrock where the magma was found together. Where the crystallization of magma, while the hot fluid through their cycles and into the surrounding rock crevice, changing the characteristics of the rock, resulting in copper-rich ore and gold. Kanania miners strike in 1906 turned into violence, 19 people were killed in the conflict has also become the fuse Mexican Revolution of 1910. Kanania another mine strike in 2007. This photo of the astronauts on the International Space Station in March 3, 2008 shooting.
8. Jordan Phosphate Mine
Jordan Phosphate Mine
Jordan Phosphate Mining is an important industry. Jordan is rich in phosphate deposits, covering the country's roughly 60 percent of the land. Phosphorus is necessary for a variety of bio-minerals, without it, you can not produce food. Some scientists fear that such an important phosphorus shortage of resources will soon be revealed, they predict, in 30 years the world will enter the "peak phosphorus" (Peak Phosphorus), the phosphorus production begin to decline. At present no such minerals, artificial substitutes. This photo is September 17, 2005 by NASA's Terra satellite Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) captured. In the diagram, the red plants, blue water, light yellow and black representatives of rocks and soil. The mining industry concentrated in the lower half of the central left side of this figure, the entire region covered with stripes.
9. The United States, Arizona, new cornelia Copper
New cornelia Arizona copper mine
About 1750, copper was originally from this area Aho town (Ajo) south of the mined out. Diagram was a large-scale open-pit mining in 1912. In 1983, due to copper prices, new cornelia Mine (New Cornelia Mine) shut down. On the right of land covered with copper mine tailings, the top of the gray rectangle is a contaminated pond, copper is extracted from inside the pond.
10. Germany Hambach mine
Germany Hambach mine
This picture on the right bright white, black and blue stripe of the opencast coal mine in central and western regions of Germany. In which a coal mine is currently being considered by the world's biggest machine "Bagger 293" mining. This wheeled excavator spoon length is twice the football field, there are 30 storeys high and mining 30 million tons per year of lignite.
