Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-brown, white, or tan.

2CO
3. This white salt is widely used in processing metal oxides. It is on the World Health Organization's List of Essential Medicines for its efficacy in the treatment of mood disorders such as bipolar disorder.
Mining is the extraction of valuable geological materials and minerals from the Earth and other astronomical objects. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Ore is natural rock or sediment that contains one or more valuable minerals concentrated above background levels, typically containing metals, that can be mined, treated and sold at a profit. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining, and is therefore considered an ore. A complex ore is one containing more than one valuable mineral.
Spodumene is a pyroxene mineral consisting of lithium aluminium inosilicate, LiAl(SiO3)2, and is a commercially important source of lithium. It occurs as colorless to yellowish, purplish, or lilac kunzite (see below), yellowish-green or emerald-green hiddenite, prismatic crystals, often of great size. Single crystals of 14.3 m (47 ft) in size are reported from the Black Hills of South Dakota, United States.
The Argyle Diamond Mine was 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 was 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 a British-Australian multinational company that is the world's second-largest metals and mining corporation. It was founded in 1873 when a group of investors purchased a mine complex on the Rio Tinto, in Huelva, Spain, from the Spanish government. It has grown through a long series of mergers and acquisitions. Although primarily focused on extraction of minerals, it also has significant operations in refining, particularly the refining of bauxite and iron ore. It has joint head offices in London, England and Melbourne, Australia.
The Jadar region begins roughly at the Osečina and it is divided in two sub-regions: Upper Jadar, which is part of much larger region of Rađevina, and Lower Jadar, which is also part of another, larger region of Podrinje. Center of the Lower Jadar is the town of Loznica, which is not on the Jadar river, but some 10 km to the southwest.
Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel.
The mining of minerals in Nigeria accounts for only 0.3% of its gross domestic product, due to the influence of its vast oil resources. The domestic mining industry is underdeveloped, leading to Nigeria having to import minerals that it could produce domestically, such as salt or iron ore. The rights to ownership of mineral resources is held by the Federal Government of Nigeria, which grants titles to organizations to explore, mine, and sell mineral resources. Organized mining began in 1903, when the Mineral Survey of the Northern Protectorates was created by the British colonial government. A year later, the Mineral Survey of the Southern Protectorates was founded. By the 1940s, Nigeria was a major producer of tin, columbite, and coal. The discovery of oil in 1956 hurt the mineral extraction industries, as government and industry both began to focus on this new resource. The Nigerian Civil War in the late 1960s led many expatriate mining experts to leave the country. Mining regulation is handled by the Ministry of Solid Minerals Development, who are tasked with the responsibility of overseeing the management of all mineral resources in Nigeria. Mining law is codified in the Federal Minerals and Mining Act of 1999. Historically, Nigeria's mining industry was monopolized by state-owned public corporations. This led to a decline in productivity in almost all mineral industries. The Obasanjo administration began a process of selling off government-owned corporations to private investors in 1999. The Nigerian Mining Industry has picked up since the "Economic Diversification Agenda", from Oil & Gas, to Agriculture, Mining, etc., began in the country.
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 regional geology of Serbia describes the geologic structure and history inside the borders of Serbia.
The Hope Downs mine is an iron ore mining complex located in the Pilbara region of Western Australia. It comprises four large open-pit mines. The mines are co-owned by the Hancock Group and Rio Tinto, and the complex was named after Hope Hancock.
The Rio Tinto Boron Mine in Boron, California is California's largest open-pit mine and the largest borax mine in the world, producing nearly half the world's borates. Ore reserves are sufficient for production through at least 2050. It is operated by the Borax division of the Rio Tinto Group.
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 Jadar mining project is a proposed mining site. The deposit is one of the largest lithium deposits in the world and also contains boron. It is planned that both lithium and boron will be recovered from the ore. The deposit contains the mineral jadarite, the only occurrence of this mineral in the world. The mine is located in western Serbia in Mačva District. The Jadar mine has reserves amounting to 118 million tonnes of ore grading 1.8% lithium oxide The deposit was discovered in 2004 and in 2017 the Rio Tinto Group planned to start mining operations in 2023.
