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 opencast 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.
