Chuquicamata copper mine, Chile

by Martyn Unsworth

Aerial view of the Chuquicamata copper mine in Northern Chile. This is the largest open pit copper mine in the world by volume. At this location the copper and molybdenum is extracted from a porphyry deposit that was formed beneath a volcano in the Andean subduction zone.
