This list of mines in the Angola is subsidiary to the list of mines article and lists working, defunct and future mines in the country and is organised by the primary mineral output. For practical purposes stone, marble and other quarries may be included in this list.
The economy of Botswana is currently one of the world's fastest growing economies, averaging about 5% per annum over the past decade. Growth in private sector employment averaged about 10% per annum during the first 30 years of the country's independence. After a period of stagnation at the turn of the 21st century, Botswana's economy registered strong levels of growth, with GDP growth exceeding 6-7% targets. Botswana has been praised by the African Development Bank for sustaining one of the world's longest economic booms. Economic growth since the late 1960s has been on par with some of Asia's largest economies. The government has consistently maintained budget surpluses and has extensive foreign-exchange reserves.
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond converts to it extremely slowly. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth.

Blood diamonds are diamonds mined in a war zone and sold to finance an insurgency, an invading army's war efforts, or a warlord's activity. The term is used to highlight the negative consequences of the diamond trade in certain areas, or to label an individual diamond as having come from such an area. Diamonds mined during the 20th–21st century civil wars in Angola, Ivory Coast, Sierra Leone, Liberia, Guinea, and Guinea-Bissau have been given the label. The term conflict resource refers to analogous situations involving other natural resources.
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow.
The Argyle Diamond Mine is a diamond mine located in the East Kimberley region in the remote north of Western Australia. Argyle was at times the largest diamond producer in the world by volume, although the proportion of gem-quality diamonds was low. It is the only known significant source of pink and red diamonds, and additionally provided a large proportion of other naturally coloured diamonds, including champagne, cognac and rare blue diamonds.
Rio Tinto Group is an Anglo-Australian multinational and the world's second-largest metals and mining corporation, behind BHP, producing iron ore, copper, diamonds, gold and uranium. The company was founded in 1873, when a multinational consortium of investors purchased a mine complex on the Rio Tinto, in Huelva, Spain, from the Spanish government. Since then, the company has grown through a long series of mergers and acquisitions to place itself among the world leaders in the production of many commodities, including aluminium, iron ore, copper, uranium and diamonds. Although primarily focused on extraction of minerals, Rio Tinto also has significant operations in refining, particularly for refining bauxite and iron ore. Rio Tinto has joint head offices in London and Melbourne.
The Ekati Diamond Mine ("Ekati") is Canada's first surface and underground diamond mine. It is located 310 km (190 mi) north-east of Yellowknife, Northwest Territories, and about 200 km (120 mi) south of the Arctic Circle, near Lac de Gras. Until 2014 Ekati was a joint venture between Dominion Diamond Mines (80%), and the two geologists who discovered kimberlite pipes north of Lac de Gras, Chuck Fipke and Stewart Blusson each holding a 10% stake in the mine, until Fipke sold his share to Dominion.
Golconda Fort, (also known as Golla konda, is a fortified citadel built by the Qutb Shahi dynasty, located in Hyderabad, Telangana, India. Because of the vicinity of diamond mines, especially Kollur Mine, Golconda flourished as a trade centre of large diamonds, known as the Golconda Diamonds. The region has produced some of the world's most famous diamonds, including the colourless Koh-i-Noor, the blue Hope, the pink Daria-i-Noor, the white Regent, the Dresden Green, and the colourless Orlov, Nizam and Jacob, as well as the now lost diamonds Florentine Yellow, Akbar Shah and Great Mogul.
Lac de Gras is a lake approximately 300 kilometres (190 mi) north east of Yellowknife, in the Northwest Territories of Canada. Lac de Gras was the centre of the diamond rush of the 1990s. There are two working, and one closed, diamond mines in the area, Diavik Diamond Mine, Ekati Diamond Mine, and the care and maintenance Snap Lake Diamond Mine. It was called Ekati by aboriginal peoples.
The Kimberley Mine or Tim Kuilmine is an open-pit and underground mine in Kimberley, South Africa, and claimed to be the deepest hole excavated by hand, although this claim is disputed.
The Mir mine, also called the Mirny mine, is an open pit diamond mine located in Mirny, Sakha Republic, in the Siberian region of eastern Russia. The mine is more than 525 meters deep, has a diameter of 1,200 m, and is one of the largest excavated holes in the world.
The Black Diamond Mines Regional Preserve is a 6,000-acre (2,400 ha) park located north of Mount Diablo in Contra Costa County, California under the administration of the East Bay Regional Park District (EBRPD). The district acquired the property in 1973. The preserve contains relics of 3 mining towns, former coal and sand mines, and offers guided tours of a former sand mine. The 60 miles (97 km) of trails in the Preserve cross rolling foothill terrain covered with grassland, California oak woodland, California mixed evergreen forest, and chaparral.

The population of Lerala was 6,871 in the 2011 census, which was a 20.5% increase from the 2001 population.
Diceratosaurus is an extinct genus of nectridean lepospondyl within the family Keraterpetontidae. Fossils of Diceratosaurus were first described by Edward Drinker Cope in 1874. The species D. brevirostris is well known from Jefferson County, Ohio, with approximately 50 specimens having been collected from the Ohio Diamond Coal Mine. The mine was situated in the village of Linton, which became obscure soon after operations were completed and the mine closed in 1921.
Tanzania is a land rich in minerals. Mining makes up more than 50% of the country's total exports, of which a large part comes from gold. The country has gold reserves of 10 million ounces, generating revenue of over a billion USD. Diamonds are also found in significant amounts. Since it was opened in 1940, the Williamson diamond mine has produced 19 million carats (3,800 kg) of diamonds. Gemstones, nickel, copper, uranium, kaolin, titanium, cobalt and platinum are also mined in Tanzania. Illegal mining and corruption are ongoing problems. In 2017, the government passed a series of bills aimed at increasing revenue from minerals after a scandal which caused the dismissal of the Minister for Energy and Minerals.
The Golconda Diamonds are the Indian diamonds mined in a specific geographic area known as Godavari delta that use to be part of Golconda Sultanet—(in the present-day Andhra Pradesh and Telangana states of India). Golconda Fort-(as a seat of Golconda Sultanet), it is essentially the eastern part of modern Hyderabad, it became an important center for diamonds enhancement, skilled lapidary and trading for which Golconda Diamond became synonymous with Golconda itself. The region is known for producing diamonds for nearly 2000 years and was the only known source of diamonds on earth until 17th century. They are Type IIa—(a high rank according to grading standards) diamonds and are devoid of nitrogen, they are large in size and weight around 0.875 carats (0.1750 g) carat, while most of those are known for their colourless clarity.
