The Hubbert peak theory says that for any given geographical area, from an individual oil-producing region to the planet as a whole, the rate of petroleum production tends to follow a bell-shaped curve. It is one of the primary theories on peak oil.
Welkom is the second-largest city in the Free State province of South Africa, located about 140 kilometres (90 mi) northeast of Bloemfontein which is the provincial capital. Welkom is also known as Circle City, City Within A Garden, Mvela and Matjhabeng. The city's Sesotho name, Matjhabeng means 'where nations meet', derived from the migrant labour system, where people of various countries such as Lesotho, Malawi and Mozambique etc. met to work in the mines of the gold fields.
Lephalale, also known as Ellisras, is a coal mining town in the Limpopo province of South Africa immediately east of the Waterberg Coalfield. The town was established as Ellisras in 1960 and named after Patrick Ellis and Piet Erasmus who settled on a farm there in the 1930s. In 2002, Ellisras was renamed Lephalale by the provincial government of Limpopo, after the main river that crosses the municipality. Lephalale is divided into three main subsections, Ellisras, Onverwacht and Marapong. Lephalale is derived from the setswana language meaning "to flow".
Uranium mining is the process of extraction of uranium ore from the ground. Over 50 thousand tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tons per year included Namibia, Niger, Russia, Uzbekistan, the United States, and China. Nearly all of the world's mined uranium is used to power nuclear power plants. Historically uranium was also used in applications such as uranium glass or ferrouranium but those applications have declined due to the radioactivity of uranium and are nowadays mostly supplied with a plentiful cheap supply of depleted uranium which is also used in uranium ammunition. In addition to being cheaper, depleted uranium is also less radioactive due to a lower content of short-lived 234
U and 235
U than natural uranium.
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.
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.
Uranium mining in the United States produced 173,875 pounds (78.9 tonnes) of U3O8 in 2019, 88% lower than the 2018 production of 1,447,945 pounds (656.8 tonnes) of U3O8 and the lowest US annual production since 1948. The 2019 production represents 0.3% of the anticipated uranium fuel requirements of the US's nuclear power reactors for the year.
Energy in Kazakhstan describes energy and electricity production, consumption and import in Kazakhstan and the politics of Kazakhstan related to energy.
Mining in South Africa was once the main driving force behind the history and development of Africa's most advanced and richest economy. Large-scale and profitable mining started with the discovery of a diamond on the banks of the Orange River in 1867 by Erasmus Jacobs and the subsequent discovery of the Kimberley pipes a few years later. Gold rushes to Pilgrim's Rest and Barberton were precursors to the biggest discovery of all, the Main Reef/Main Reef Leader on Gerhardus Oosthuizen's farm Langlaagte, Portion C, in 1886, the Witwatersrand Gold Rush and the subsequent rapid development of the gold field there, the biggest of them all.
Uranium One is an international group of companies, part of the management circuit of the TENEX Group of Rosatom State Corporation. Since 2013, it is a wholly owned subsidiary of Moscow-based Uranium One Group, a part of the Russian state-owned nuclear corporation Rosatom.
The mineral industry of Russia is one of the world's leading mineral industries and accounts for a large percentage of the Commonwealth of Independent States' production of a range of mineral products, including metals, industrial minerals, and mineral fuels. In 2005, Russia ranked among the leading world producers or was a significant producer of a vast range of mineral commodities, including aluminum, arsenic, cement, copper, magnesium compounds and metals, nitrogen, palladium, silicon, nickel and vanadium.
The second-largest mineral industry in the world is the mineral industry of Africa, which implies large quantities of resources due to Africa being the second largest continent, with 30.37 million square kilometres of land.With a population of 1.4 billion living there, mineral exploration and production constitute significant parts of their economies for many African countries and remain keys to economic growth. Africa is richly endowed with mineral reserves and ranks first in quantity of world reserves for bauxite, cobalt, industrial diamond, phosphate rock, platinum-group metals (PGM), vermiculite, and zirconium.
The mineral industry of Mozambique plays a significant role in the world's production of aluminium, beryllium, and tantalum. In 2006, Mozambique's share of the world's tantalum mine output amounted to 6%; beryllium, 5%; and aluminium, 2%. Other domestically significant mineral processing operations included cement and natural gas.
The mineral mining industry is a crucial piece of the Economy of Niger. Exports of minerals consistently account for 40% of exports.
Radioactive ores were first extracted in South Australia at Radium Hill in 1906 and Mount Painter in 1911. 2,000 tons of ore were treated to recover radium for medical use. Several hundred kilograms of uranium were also produced for use in ceramic glazes.
South Africa has a large energy sector, being the third-largest economy in Africa. The country consumed 227 TWh of electricity in 2018. The vast majority of South Africa's electricity was produced from coal, with the fuel responsible for 88% of production in 2017. South Africa is the 7th largest coal producer in the world. As of July 2018, South Africa had a coal power generation capacity of 39 gigawatts (GW). South Africa is the world's 14th largest emitter of greenhouse gases. South Africa is planning to shift away from coal in the electricity sector and the country produces the most solar and wind energy by terawatt-hours in Africa. The country aims to decommission 34 GW of coal-fired power capacity by 2050. It also aims to build at least 20 GW of renewable power generation capacity by 2030. South Africa aims to generate 77,834 megawatts (MW) of electricity by 2030, with new capacity coming significantly from renewable sources to meet emission reduction targets. Through its goals stated in the Integrated Resource Plan, it announced the Renewable Energy Independent Power Producer Procurement Programme, which aims to increase renewable power generation through private sector investment.
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.
Mining is important to the national economy of Mongolia. Mongolia is one of the 29 resource-rich developing countries identified by the International Monetary Fund and exploration of copper and coal deposits are generating substantial additional revenue. Coal, copper, and gold are the principal reserves mined in Mongolia. Several gold mines are located about 110 kilometres (68 mi) north of Ulaanbaatar, such as Boroo Gold Mine and Gatsuurt Gold Mine. Khotgor Coal Mine is an open-pit coal mining site about 120 kilometres (75 mi) west of Ulaangom. Ömnögovi Province in the south of Mongolia is home to large scale mining projects such as the Tavan Tolgoi coal mine and the Oyu Tolgoi copper mine. Oyu Tolgoi mine is reported to have the potential to boost the national economy by a third but is subject to dispute over how the profits should be shared. The International Monetary Fund (IMF) has estimated that 71 percent of the income from the mine would go to Mongolia.
