Coltan is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite, and the tantalum-dominant mineral is tantalite.
Mining in Australia has long been a significant primary sector industry and contributor to the Australian economy by providing export income, royalty payments and employment. Historically, mining booms have also encouraged population growth via immigration to Australia, particularly the gold rushes of the 1850s. Many different ores, gems and minerals have been mined in the past and a wide variety are still mined throughout the country.
Pebble Mine is the common name of a proposed copper-gold-molybdenum mining project in the Bristol Bay region of Southwest Alaska, near Lake Iliamna and Lake Clark. Discovered in 1987, optioned by Northern Dynasty Minerals in 2001, explored in 2002, drilled from 2002-2013 with discovery in 2005. Preparing for the permitting process began and administrative review lasted over 13 years.
The mining industry of the Democratic Republic of the Congo produces copper, diamonds, tantalum, tin, gold, and more than 63% of global cobalt production. Minerals and petroleum are central to the DRC's economy, making up more than 95% of the value of its exports.
Mining in Afghanistan was controlled by the Ministry of Mines and Petroleum, prior to the August 15th takeover by the Taliban. It is headquartered in Kabul with regional offices in other parts of the country. Afghanistan has over 1,400 mineral fields, containing barite, chromite, coal, copper, gold, iron ore, lead, natural gas, petroleum, precious and semi-precious stones, salt, sulfur, lithium, talc, and zinc, among many other minerals. Gemstones include high-quality emeralds, lapis lazuli, red garnet and ruby. According to a joint study by The Pentagon and the United States Geological Survey, Afghanistan has an estimated US$1 trillion of untapped minerals.
The mineral industry is one of the main sectors of the Armenian economy and in 2017 accounted for 30.1% of its exports.
Natural resource economics deals with the supply, demand, and allocation of the Earth's natural resources. One main objective of natural resource economics is to better understand the role of natural resources in the economy in order to develop more sustainable methods of managing those resources to ensure their availability for future generations. Resource economists study interactions between economic and natural systems, with the goal of developing a sustainable and efficient economy.
Helvetia is a ghost town in Pima County, Arizona, United States that was settled in 1891 and abandoned in the early 1920s. Helvetia is an ancient name for Switzerland.
Mining in the United States has been active since the beginning of colonial times, but became a major industry in the 19th century with a number of new mineral discoveries causing a series of mining rushes. In 2015, the value of coal, metals, and industrial minerals mined in the United States was US $109.6 billion. 158,000 workers were directly employed by the mining industry.
Barton Mine, also known as Net Lake Mine, is an abandoned surface and underground mine in Northeastern Ontario, Canada. It is located about 0.50 km (0.31 mi) north of the Temagami Arena in Temagami North and just east of the Ontario Northland Railway in northwestern Strathy Township. Dating back to the early 1900s, it is one of the oldest mines in Temagami. Barton was the site of a fire in the early 1900s, after which it never had active mining again.
The Mountain Pass Rare Earth Mine and Processing Facility, owned by MP Materials, is an open-pit mine of rare-earth elements on the south flank of the Clark Mountain Range in California, 53 miles (85 km) southwest of Las Vegas, Nevada. In 2020 the mine supplied 15.8% of the world's rare-earth production. It is the only rare-earth mining and processing facility in the United States.
Kerr-Sulphurets-Mitchell (KSM) is an active mine exploration project 65 km northwest of Stewart, British Columbia. The property is 100% owned by Toronto-based Seabridge Gold. Denver-based royalty company Royal Gold owns a 2% net smelter return royalty on the mine. Since May 2011, the project has also been called Kerr-Sulphurets-Mitchell-Iron Cap due to the addition of significant reserves from the Iron Cap region.
Namibia has one of the richest uranium mineral reserves in the world. There are currently two large operating mines in the Erongo Region and various exploration projects planned to advance to production in the next few years.
The mining industry of Lesotho is mostly concentrated on diamond mining and as such the mining sector in the country has not played any significant role in furthering its economy. Apart from diamonds, the country's main mineral resources have been identified as base metals, clays, dimension stone, sand, gravel and uranium. The lack of initiative to extract other minerals commercially is mainly attributed to the inadequacy of infrastructure and finances. Between 2000 and 2011, the percentage of GDP contributed by diamond mining to Lesotho's economy rose from "virtually zero" to about 4%.
The mining industry of Togo is centred mainly around the extraction of phosphate, ranking it 19th in world production. Other minerals extracted are diamond, gold, and limestone. More minerals identified but yet to be brought into production mode are manganese, bauxite, gypsum, iron ore, marble, rutile, and zinc. The mineral sector contributes 2.8% to the country's gross domestic product (GDP).
The mining industry of Liberia has witnessed a revival after the civil war which ended in 2003. Gold, diamonds, and iron ore form the core minerals of the mining sector with a new Mineral Development Policy and Mining Code being put in place to attract foreign investments. In 2013, the mineral sector accounted for 11% of GDP in the country and the World Bank projected a further increase in the sector by 2017.
Molybdenum mining in the United States produced 65,500 metric tons of molybdenum in 2014, worth US$1.8 billion. The US was the world's second-largest molybdenum producer, after China, and provided 25% of the world's supply of molybdenum.
The mining industry of Cyprus is synonymous with copper extraction which began around 4,000 BC. Copper dominates the mining sector along with mining of iron pyrite, gold, chromites and asbestos fibers, bentonite, cement, and also petroleum. Though at one time, copper was a mainstay of the economy, as of 2012, the mining sector does not contribute in a significant way to the GNP.
The mining industry of Yemen is at present dominated by fossil mineral of petroleum and liquefied natural gas (LNG), and to a limited extent by extraction of dimension stone, gypsum, and refined petroleum. Reserves of metals like cobalt, copper, gold, iron ore, nickel, niobium, platinum-group metals, silver, tantalum, and zinc are awaiting exploration. Industrial minerals with identified reserves include black sands with ilmenite, monazite, rutile, and zirconium, celestine, clays, dimension stone, dolomite, feldspar, fluorite, gypsum, limestone, magnesite, perlite, pure limestone, quartz, salt, sandstone, scoria, talc, and zeolites; some of these are under exploitation.
Mining has been conducted on an industrial scale in present-day Canada since the late 18th century. The industry remains an important aspect of the economy of Canada to this day, particularly in the North, and Canadian-domiciled mining companies have increasingly expanded their operations globally.
