Chuquicamata is one of the largest copper mines in the world. Located in northern Chile, the facility has been open since 1882, but much of the mine’s excavation and expansion has occurred since the late 1960s when the Chilean government assumed control of the copper industry. Chuquicamata reaches a depth of 850 meters (2,790 ft) and produces over 400,000 tons of metal annually. -22.305461°, -68.902242° Source imagery: NASA / Google Timelapse | Daily Overview
