The Mustavaara mine is one of the largest vanadium mines in Finland. [1] The mine is located in Oulu Province. [1] The mine has reserves amounting to 30 million tonnes of ore grading 0.91% vanadium. [1]
Vanadium is a chemical element; it has symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.
Group 5 is a group of elements in the periodic table. Group 5 contains vanadium (V), niobium (Nb), tantalum (Ta) and dubnium (Db). This group lies in the d-block of the periodic table. This group is sometimes called the vanadium group or vanadium family after its lightest member; however, the group itself has not acquired a trivial name because it belongs to the broader grouping of the transition metals.
The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers. The battery uses vanadium's ability to exist in a solution in four different oxidation states to make a battery with a single electroactive element instead of two. For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids.
Ferrovanadium (FeV) is an alloy formed by combining iron and vanadium with a vanadium content range of 35–85%. The production of this alloy results in a grayish silver crystalline solid that can be crushed into a powder called "ferrovanadium dust". Ferrovanadium is a universal hardener, strengthener and anti-corrosive additive for steels like high-strength low-alloy steel, tool steels, as well as other ferrous-based products. It has significant advantages over both iron and vanadium individually. Ferrovanadium is used as an additive to improve the qualities of ferrous alloys. One such use is to improve corrosion resistance to alkaline reagents as well as sulfuric and hydrochloric acids. It is also used to improve the tensile strength to weight ratio of the material. One application of such steels is in the chemical processing industry for high pressure high throughput fluid handling systems dealing with industrial scale sulfuric acid production. It is also commonly used for hand tools e.g. spanners (wrenches), screwdrivers, ratchets, etc.
Vanadium(III) chloride describes the inorganic compound with the formula VCl3 and its hydrates. It forms a purple anhydrous form and a green hexahydrate [VCl2(H2O)4]Cl·2H2O. These hygroscopic salts are common precursors to other vanadium(III) complexes and is used as a mild reducing agent.
Vanadium(II) oxide is the inorganic compound with the idealized formula VO. It is one of the several binary vanadium oxides. It adopts a distorted NaCl structure and contains weak V−V metal to metal bonds. VO is a semiconductor owing to delocalisation of electrons in the t2g orbitals. VO is a non-stoichiometric compound, its composition varying from VO0.8 to VO1.3.
Vanadium nitride, VN, is a chemical compound of vanadium and nitrogen.
Placerville is a census-designated place (CDP) and post office in and governed by San Miguel County, Colorado, United States. The Placerville post office has the ZIP Code 81430. At the United States Census 2020, the population of the Placerville CDP was 362.
Tiger is a former populated place in Pinal County in the U.S. state of Arizona. The town was settled as Schultzcirca 1881 in what was then the Arizona Territory, then later reestablished as Tiger after World War I.
Sharsha is an upazila of Jessore District in the Division of Khulna, Bangladesh.
Uranium mining in Colorado, United States, goes back to 1872, when pitchblende ore was taken from gold mines near Central City, Colorado. The Colorado uranium industry has seen booms and busts, but continues to this day. Not counting byproduct uranium from phosphate, Colorado is considered to have the third largest uranium reserves of any US state, behind Wyoming and New Mexico.
The Potosi Mining District, or Potosi, was an area in Clark County of southern Nevada, U.S. It is listed on the National Register of Historic Places and includes three structures. The town was named after the famous silver-mining city of Potosi, Bolivia.
Patrónite is the vanadium sulfide mineral with formula VS4. The material is usually described as V4+(S22−)2. Structurally, it is a "linear-chain" compound with alternating bonding and nonbonding contacts between the vanadium centers. The vanadium is octa-coordinated, which is an uncommon geometry for this metal.
Rovana is an unincorporated community in Inyo County, California. It is located at the western edge of Owens Valley, 5.5 miles (8.9 km) north-northeast of Mount Tom, at an elevation of 5141 feet.
The Lac Doré Vanadium Deposit is a vanadium deposit first discovered by the Government of Quebec at Lac Doré. The closest mining town to the site is Matagami. In 1998, its control was transferred to the Société générale de financement du Québec, and its wholly owned subsidiary SOQUEM
Vuorokas iron mine was active in Vuolijoki during the years 1965-1985. During this time there were mined 1.348 million tons of ore. The ore contained on average 34% iron, 7.5% titanium and 0.2% vanadium. Together with Otanmäki mine Vuorokas mine was a major vanadium producer in the world.
Khlong Khanan railway station is a railway station located in Ban Khuan Subdistrict, Lang Suan District, Chumphon. It is a class 3 railway station located 541.032 km (336.2 mi) from Thon Buri railway station.
Rankotea is a village located just outside the town of Brits in the North West province under the Madibeng municipality of South Africa. The village has a vanadium extracting mine called Bushveld Vametco located just before you enter the residence. A solar&battery is being built to supply 10% of the mine's power needs. Bushveld Vametco mine provides the community of Rankotea with funds where they may need them like funding few students of Rankotea with university fees. It also has provided funds to renovate schools and clinics. The community includes a primary school named Rantsou and a secondary school named Ramadikela. It also have a power station named RoshCon. The residents use the health care service of the mobile clinic provided by Madibeng that comes once a month and during the month they use that of the community of Mothotlung. They also use the SAPS and Postal Office of Mothotlung.
In 2015, 27.6 million metric tons of marketable phosphate rock, or phosphorite, was mined in the United States, making the US the world's third-largest producer, after China and Morocco. The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 billion.
The Minas Ragra was a large vanadium mine in the Pasco Region of Peru. The deposit was discovered by a United States Geological Survey expedition on November 20. 1905. Members of this expeditions were Donnel Foster Hewett and José J. Bravo In this deposit the mineral patrónite was first discovered by a member of the expedition Antenor Rizo-Patron. A mine was established in very short time by the Vanadium Corporation of America. By 1914 75% of the world vanadium ore production was coming from the Minas Ragra in Peru, making the mine the world leading producer of vanadium. With the production of vanadium as side product of uranium mining from carnotite the mine had to close in 1955.
