Open pit copper mining is a process of extracting the valuable metal, copper, from large, open pits. The process typically begins by removing overburden, or earth and rock that sits on top of the ore. Then bulldozers and large backhoes are used to excavate the ore from the pit. Next, giant dump trucks are used to haul the ore to the surface for processing at the shelter. This process is very dangerous and harmful to the environment.

Copper is a metal that is widely used in the production of household and industrial products. It is most commonly used in electrical wiring and copper plumbing. It is also used in automobiles and other transportation vehicles, as well as in electronic products such as computers and cell phones.
Copper is usually gotten from open pit mines, and these mines are often located in rugged terrain where the environment is often not suitable for human habitation. Such mines generally require extensive engineering work to build them and maintain them throughout the mining operation. Copper deposits are found in approximately 50 countries around the world, including the United States, China, Peru, Chile, Mexico, Australia, and the United Kingdom. Although copper is one of the most common elements on our planet, only about 8% of the world’s supply of copper has been discovered to date.
After Open pit copper mining has been carried out successfully, the extraction of the copper concentrate is initiated. Upon successful extraction of the copper concentrate, which is done in the concentrator plant, it is transported to the shelter for further processing. At the shelter, it is processed to remove the Sulphur and other impurities that remain in the ore. Next, it is melted down, poured into molds and then allowed to cool. Once the metal is cooled, it is ready to be used to make different types of products, such as wire and pipe. These products are then sold to the manufacturing companies that produce them for use in a wide range of industries, including power, construction and transportation.
Which is the largest open pit copper mine in the world?
The Bingham Canyon Mine in Utah is the largest open pit copper mine in the world. The mine was opened in 1906 and is now operated by Rio Tinto Group, a multinational mining and metal corporation based in England. The mine has a combined depth of more than 2 miles! It is recorded that 30 open pit copper mining operations have been carried out successfully at Bingham Canyon Mine.
Where is the Bingham Canyon Mine located?
The Bingham Canyon Mine is located in Utah. The mine is located in the Great Salt Lake Desert near Salt Lake City. It is known for its spectacular turquoise-colored waters and is one of only eight places on Earth where you can see the sunrise and sunset from the same spot.
Is open pit copper mining safer than shaft mining?
“Open pit mining generally usually provides higher efficiency with lower costs than underground mining due to lower operational costs such as ventilation and pumping.” Says Minerals Council of Australia CEO, Brendan Pearson. Compared to shaft mining, which is more hazardous due to falling rock, the risk of accidental death is lower with open pit mining because the miners are not operating in narrow shafts where death can occur from falling rocks. In other words, open pit mining is a safer method of extraction. It is also less harmful to the environment because the waste products that are produced during the mining process can be recycled instead of being disposed of in a landfill.
How is copper gotten from an open pit mine?
There are mainly two ways to carry out Open pit copper mining (to extract copper from open pit mines). The first is using solution mining. This process requires injecting a mixture of water and copper salt into a pit to remove the minerals for the surrounding rock. The mixture is then pumped to the surface and the copper is separated from the impurities and deposited into huge tanks or ponds.
The second is by heap leaching. This method involves piling the waste rock and mining waste at the bottom of the pit and then soaking it with sulfuric acid to dissolve the metals. Once dissolved, the mixture is pumped to the surface where it is run through a series of filters to separate the copper from the rock and other impurities.

What are the risks associated with open pit copper mining?
There are many risks that are associated with open pit copper mining. One of the most significant risks is the contamination of the surrounding groundwater supplies. Copper mining operations release large amounts of acidic wastewater into the surrounding soil and water during the extraction process. This contaminated water can seep into the surrounding groundwater supplies, where it can cause serious damage.
Other potential environmental impacts include the destruction of wildlife habitats and the permanent loss of land habitat. Wildlife species that inhabit the area near open pit mines can be seriously affected by the mining operations. They can become trapped underground by the excavation equipment or poisoned by the chemicals and wastewater released by the mines.
Environmental Effects of Open Pit Mining
One of the biggest environmental problems with open pit copper mining is contamination of the ground water. The chemicals used in the mining process tend to leak into the groundwater and then contaminate nearby streams and rivers. Mining, and open pit copper mining, also releases large amounts of carbon dioxide into the atmosphere. Both of these effects can have a devastating effect on the surrounding environment. The ecological impact of open pit mining can be compounded if the miners use toxic tailings ponds to dispose of the waste material instead of properly disposing of it.
