Chuquicamata is the world's largest open-pit copper mine. It can only be visited on a free guided tour organized by the Chilean state-owned copper company Codelco. Although mining operations run throughout the year, tours are only conducted from Mondays to Fridays, holidays excepted. Reservations need to be made in advance through email at visitas@codelco.cl or through telephone at +56 552322122. You need to provide your name, number of people, number of people of 7 years and below, your country and any medical issues that could influence the tour.
The tour departs at 13:00 from the Codelco Norte visitor office on the north side of Calama, at the junction of Central Sur and Granaderos. The office is accessible by Buses B and D, and should not be confused with the Codelco Norte headquarters building opposite the Calama Plaza Mall on Balmaceda.
Your should wear long trousers, long sleeve shirt and covered shoes. You will get a helmet and warning west at the office. The tour itself is free but you will be asked for a voluntary donation for the children's fund.
The tour is conducted simultaneously in English and Spanish. It begins with a circuit around Chuquicamata town, once a thriving company town with banks, restaurants and playgrounds, but which has since been evacuated due to legal and health issues. The bus does not stop for visitors to get off in the town. The tour bus continues into the mine, passing mining trucks and old equipment, and stops to let visitors off at the Mirador, which offers a panoramic view of the central mine. There are some informational posters on the copper and mining extraction process, and a pile of copper ore for visitors to pick through.
You also can sign up at the local Tourist Office. Or, if everything else fails, you can also contact the tourism office in Antofagasta.
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.
