Nine amazing open-pit mines in the world

Open-pit mining, also known as open-pit mining, is a process of removing the covering on the ore body, obtaining the required minerals, and extracting useful minerals from the open mining field. The landscape created by this technology is no worse than those of nature. Here are nine amazing open-pit mines.

1. Milne, Russia-This is an inactive diamond mine, located in Milne, Eastern Siberia. It is the largest diamond mine in the world and the second largest open-pit mine in the world, with a pit depth of 525m and a diameter of 1200m. It is one of the earliest and largest tubular diamond mines in the former Soviet Union, and this mine has been abandoned at present. It is said that when the mine is in mining operation, it takes two hours for a truck to drive from the bottom to the top of the mine. Because the area of the mine is too large, it is forbidden for helicopters to fly over it to prevent the strong airflow generated in the pit from inhaling helicopters.

2. Bingham Canyon Mine, USA-Bingham Canyon Mine is an open-pit copper mine located in Salt Lake City, Utah. It is the largest and deepest open pit mine in the world, 0.6 miles (0.97 kilometers) wide and 2.5 miles (4 kilometers) wide!

3. Karguli Super Gold Mine-Australia's largest open-pit gold mine. The pit is rectangular in shape and about 3.5 kilometers long, 1.5 kilometers wide and 570 meters deep. 

4. Dakong (Kimberly Mine), South Africa-Kimberly Diamond Mine is located in Cape Province, South Africa, and is a world-famous diamond capital. Besides the world-famous diamonds, Kimberly is also famous for this huge masonry mining site, also known as Kimberly Hole. The Kimberly Cave was built in 1870, and a total of about 3 tons of diamond mines were produced before it was closed in 1914. It is 1097 meters deep, with an entrance diameter of about 500 meters, and covers an area of 17 hectares. In order to dig such a big hole, more than 22 million tons of soil were dug from here. Nowadays, it has become a key scenic spot for tourists to visit and enjoy.

5. Deiwick Diamond Mine, Canada-Deiwick Diamond Mine is located in the northwest territory of Canada. This mine was first excavated in 2003, and it can produce 8 million carats or 1,600 kilograms of diamonds every year.

6.Ekati Diamond Mine, Canada-Aikadi Diamond Mine is the first open-air and underground diamond mine in Canada, which is located about 310 kilometers northeast of Yellowknife, about 200 kilometers away from the Arctic Circle and close to La Quetglas. From 1998 to 2009, the six open-pit mines of Aikadi Diamond Mine produced 40 million carats of diamonds. After the high-quality ore near the surface was mined, the Aikadi diamond mine began to be mined underground.

7. Glasberg Copper Mine, Indonesia-Glasberg Mine is located in Papua Province, Indonesia. It is the world's largest gold producing area and the third largest copper mine in the world, with an annual output of more than 58 million grams of gold, 170 million grams of silver and 610,000 tons of copper.。

8.Chuquicamata(Chuqui), Chile is a copper mine in Chile. Although it is not the mine with the largest copper reserves in the world, it is currently the mine that produces the most copper in the world. This mine is now 850 meters deep.

9. Escondida Copper Mine, Chile-Escondida mine is located in the Atacama Desert in northern Chile. Mining began in 1990, and its annual output ranks first among copper mines in the world. In 2007, the output of copper was 1.5 million tons, valued at more than 10 billion US dollars, accounting for nearly one tenth of the global copper output.
