La Escondida Mine
The mine is located in the Andes Mountains to the east of the city of Antofagasta, at an altitude of 3,100 meters.
With an annual production of 80,000 tons of refined copper, it is the biggest in the world. The ore is extracted in the open-cast mine and then taken to a gigantic refining plant. From here the metal is taken to Puerto Coloso, on the coast, to be exported.
The mine has reserves of 2,100 million tons of ore with a legal standard concentration of 1.3%.
There is a viewpoint where information about the operations of the Escondida Mine is provided through display panels and leaflets. You can also visit the mine in the programmed visits – you should inquire in advance for the timetable.
