Chuquicamata is the largest open pit copper mine in terms of excavated volume in the world. It is located in the north of Chile, just outside Calama, at 2,850 m (9,350 ft) above sea level. It is 215 km (134 mi) northeast of Antofagasta and 1,240 km (770 mi) north of the capital, Santiago. Flotation and smelting facilities were installed in 1952, and expansion of the refining facilities in 1968 made 500,000 tons annual copper production possible in the late 1970s. Previously part of Anaconda Copper, the mine is now owned and operated by Codelco, a Chilean state enterprise, since the Chilean nationalization of copper in the late 1960s and early 1970s. Its depth of 850 metres (2,790 ft) makes it the second deepest open-pit mine in the world, after Bingham Canyon Mine in Utah, United States.

<span class="mw-page-title-main">Mining in Japan</span> Overview of mining in Japan

Mining in Japan is minimal because Japan does not possess many on-shore mineral resources. Many of the on-shore minerals have already been mined to the point that it has become less expensive to import minerals. There are small deposits of coal, oil, iron and minerals in the Japanese archipelago. Japan is scarce in critical natural resources and has been heavily dependent on imported energy and raw materials. There are major deep sea mineral resources in the seabed of Japan. This is not mined yet due to technological obstacles for deep sea mining.

<span class="mw-page-title-main">Mining in Iran</span>

Mining in Iran is still under development, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014. Mineral production contributes only 0.6 percent to the country's GDP. Add other mining-related industries and this figure increases to just four percent (2005). Many factors have contributed to this, namely lack of suitable infrastructure, legal barriers, exploration difficulties, and government control.

Resources are classified as either biotic or abiotic on the basis of their origin. India contains a multitude of both types of resource and its economy, especially in rural areas, is heavily dependent on their consumption or export. Due to overconsumption, they are rapidly being depleted.
