Bajo de la Alumbrera mine was a gold and copper mine in the Catamarca Province, of Argentina. It was the largest and the oldest open pit mine in Argentina.
The mine opened in 1997 and was met with local opposition before complaints about environmental pollution. The mine closed in 2018.
Bajo de la Alumbrera mine was a gold and copper mine in the Catamarca Province, of Argentina. [1] It is located 70 kilometres west of Andalgalá [1] and cost $1.2 billion to open. [2]
It is the largest and the oldest open pit mine in Argentina. [1] [3] In 2000, the mine was the fourteenth largest gold mine in the world and the ninth largest copper mine. [2]
The mine had 648 million metric tons of 0.54% copper and gold at 0.67 grams per metric ton. [2]
The mine uses cyanide and sulphuric acid to extract the copper and gold from the ore. It uses between 60 million and 100 million litres of water per day. The mine produces 314,000 tons of ore daily, which is mixed with water into mud that is piped 216 kilometres to San Miguel de Tucumán. In Tucumán, the mud is dried and concentrated before being moved by train to the Port of Rosario for separation and smelting outside Argentina. [1]
A 930 hectare tailing pond captures mine effluent. [1]
The mine opened in 1997, the first open pit mine in Argentina at the time. The mine's opening was met with complaints from activist, academics and the media. Although disputed by the mine's owners, Minera Alumbrera [ES], accusations linking the mine's activities to land, air occurred. [4] In 2009, Minera Alumbrera was jointly owned by Xstrata, Goldcorp, Northern Orion Resources, and the Argentinian government owned company: Mineral Deposits of the Waters of Dionysius. [1]
In 2008, the mine's owners were investigated for corruption, environmental criminality and gold smuggling. [1]
The 2009, 2010, and 2011 sustainability report published by the mine's owners downplayed environmental concerns raised about the mine. In 2011 and 2012, local community members protested the mine, including blocking the National Route 40 near Belén in May 2012. Protests were stopped by police without any dialogue with mine owners. [4]
The mine stopped operating at the end of 2018. [5] By 2018, the nearby Andalgalá community had successfully campaigned to halt the opening of the nearby Agua Rica mine for eight years. [6]
The mine's water consumption is the cause of desertification and activists have reported five leaks from the mine's pipelines. The water removed from the mud in Tucumán goes into the DP2 canal before reaching the Sali-Dulce river. The river is without plant and fish life. The canal has copper and arsenic at 20,000 the legal limit and levels of cadmium 5,000 times and mercury 10,000 times the legal limit, according to Bajo Alumbrera activist organization. [1]
Mining is the extraction of valuable geological materials from the Earth and other astronomical objects. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow.

Chuquicamata is the largest open pit copper mine in terms of excavated volume in the world. It is located in the north of Chile, just outside Calama, at 2,850 m (9,350 ft) above sea level. It is 215 km (134 mi) northeast of Antofagasta and 1,240 km (770 mi) north of the capital, Santiago. Flotation and smelting facilities were installed in 1952, and expansion of the refining facilities in 1968 made 500,000 tons annual copper production possible in the late 1970s. Previously part of Anaconda Copper, the mine is now owned and operated by Codelco, a Chilean state enterprise, since the Chilean nationalization of copper in the late 1960s and early 1970s. Its depth of 850 metres (2,790 ft) makes it the second deepest open-pit mine in the world, after Bingham Canyon Mine in Utah, United States.
Codelco is a Chilean state-owned copper mining company. It was formed in 1976 from foreign-owned copper companies that were nationalised in 1971.

The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest man-made excavation, and deepest open-pit mine in the world, which is considered to have produced more copper than any other mine in history – more than 19,000,000 short tons. The mine is owned by Rio Tinto Group, a British-Australian multinational corporation. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery. The mine has been in production since 1906, and has resulted in the creation of a pit over 0.75 miles (1,210 m) deep, 2.5 miles (4 km) wide, and covering 1,900 acres. It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine. The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013.

The Cobre mine was a copper mine in Cuba, the oldest in the new world. The open pit mine was operated from 1544 to 1998. The Spanish used slave labour and free coloured labour to work the mine. After it had been abandoned, in the 19th century a British company acquired the mine and reopened it, again using slaves and free coloured labourers, but also using skilled Cornish miners and steam engines from Cornwall to operate pumps. The mine was abandoned again, then reopened by an American company at the start of the 20th century. After the Cuban Revolution it was taken over by the state. After being finally abandoned the pit is now filled with a mineral-rich lake.
