Geology

The Atacama Desert in the north of the country contains major reserves of copper, gold, silver and industrial metals, it is the heart of Chile's mining industry. Chile's copper mines provide over 30% of the world's mine production of recoverable copper, according to to statisctics of the U.S. Department of the Interior.

Chuquicamata is an open cast copper mine, where a relatively poor copper ore is mined in impressive huge amounts. Modern mining and smelting technology allows the usage of such depostits at unrivaled low costs. The ore contains only between 1,13% and 1,18% metals, most of it copper, but also molybdenum and selenium in a very low proportion.

The Chuquicamata mine produces sulfidic ores, whilst the nearby Chuqui Sur mine, formerly known as Exótica, primarily produces oxide ores.

The tour of the working mine is offered by the mining company. It is free, but the visitors are requested to donate a small amount for the non-profit organization Chuqui Ayuda a la Infancia which helps children from the nearby village Calama. It is necessary to make a reservation at least three days in advance, however, it is possible to do this by email.


Description

The name Chuquicamata is a word from the Aymara language and refers to the chuco or chuqui Native American Indian group. They worked the copper deposits here in pre-Hispanic times to make their weapons and tools.

The opencast was the biggest pit in the world during the nineties. But it has lost its foremost position and the new Escondida Copper Mine is today the world's largest producing mine with 750,000 metric tons of production which was 5.6% of the world's production in 2000.

In the ninties Chuquicamata proiduced annually 600,000 to 650,000 metric tons of copper, and in 2000 this was 4.9% of the world's production. The mine also produces around 13,500t of molybdenum every year.

The visit of the mine is a popular trip and part of most tour company schedules. But the mine is a working mine, and so the visits are more or less a kind of promotion visit of the mining company.

Arrive early, preferably before 9.45 at the Oficina Ayuda a la Infancia, at the top of Avenida JM Carrera. You will need a passport and a small donation, about US$0.50. Demand is high in January and February, so you need to get there early. If there is sufficient demand afternoon tours can be arranged. To enter the smelter building you must wear sturdy boots, long trousers and a long-sleeved jacket although the mining company provides protective clothing as well.
