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.
The Republic of Karelia, Karjala or Karelia, is a republic of Russia situated in the northwest of the country. The republic is a part of the Northwestern Federal District, and covers an area of 172,400 square kilometres, with a population of 533,121 residents. Its capital is Petrozavodsk.
Karelian is a Finnic language spoken mainly in the Russian Republic of Karelia. Linguistically, Karelian is closely related to the Finnish dialects spoken in eastern Finland, and some Finnish linguists have even classified Karelian as a dialect of Finnish, though in the modern day it is widely considered a separate language. Karelian is not to be confused with the Southeastern dialects of Finnish, sometimes referred to as karjalaismurteet in Finland. In the Russian 2020–2021 census, around 9,000 people spoke Karelian natively, but around 14,000 said to be able to speak the language.
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.
North Karelia is a region in eastern Finland. It borders the regions of Kainuu, North Savo, South Savo and South Karelia, as well as Russia's Republic of Karelia. It is the easternmost region of Finland and shares a 300 kilometres (190 mi) border with Russia. The city of Joensuu is the capital and the largest settlement of the region.
Uranium mining in Utah, a state of the United States, has a history going back more than 100 years. Uranium mining started as a byproduct of vanadium mining about 1900, became a byproduct of radium mining about 1910, then back to a byproduct of vanadium when the radium price fell in the 1920s. Utah saw a uranium boom in the late 1940s and early 1950s, but uranium mining declined in the 1980s. Since 2001 there has been a revival of interest in uranium mining, as a result of higher uranium prices.
Karjalan Sanomat is a weekly Finnish language newspaper from the Republic of Karelia, published in Petrozavodsk. The newspaper was founded in 1920 as 'Karjalan kommuuni'.
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.
Ectoedemia occultella, the small birch leafminer, is a moth of the family Nepticulidae. It has a Holarctic distribution. It is found in most of Europe, east through Russia to Japan. It is also present in North America. Mines very similar to that of Ectoedemia occultella have been found on Rosaceae species in Nepal and Japan and these may belong to this species.
Vanadium(V) fluoride is the inorganic compound with the chemical formula VF5. It is a colorless volatile liquid that freezes near room temperature. It is a highly reactive compound, as indicated by its ability to fluorinate organic substances.
Karelianite is an rare mineral, a natural form of vanadium(III) oxide, V2O3. In terms of chemistry it is vanadium-analogue of hematite, corundum, eskolaite, tistarite, bixbyite, avicennite, and yttriaite-(Y). The name comes from Karelia, a region on the Finnish-Russian border. It may be associated with magnesium-rich rocks.

The Green Giant mine is one of the largest vanadium mines in Madagascar. The mine is located in Betioky Sud in Atsimo-Atsinanana. The mine has reserves amounting to 59.2 million tonnes of ore grading 0.68% vanadium. In August of 2007, the Canadian company Uranium Star Corp announced an agreement where it would buy a 75% ownership stake in the mine from Madagascar Minerals and Resources Sarl, and then bought full ownership in 2009. An aerial survey was conducted in 2007 and samples were drilled in 2008. Uranium Star Corp rebranded as Energizer Resources Inc in December 2009, and then as NextSource Materials Inc in April 2017. The mine is 11 kilometers from the Molo mine, which is also owned by NextSource.
