Manganese was an unincorporated community in Wood County, West Virginia, United States.
Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.
Cuming County is a county in the U.S. state of Nebraska. As of the 2010 United States Census, the population was 9,139. Its county seat is West Point.
Crimora is a census-designated place (CDP) in Augusta County, Virginia, United States. The population was 2,209 at the 2010 census, a 23% increase from the 1,796 reported in 2000. It is part of the Staunton–Waynesboro Micropolitan Statistical Area.
Axinite is a brown to violet-brown, or reddish-brown bladed group of minerals composed of calcium aluminium boro-silicate, (Ca,Fe,Mn)3Al2BO3Si4O12OH. Axinite is pyroelectric and piezoelectric.
Manganese dioxide is the inorganic compound with the formula MnO
2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO
2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery. MnO
2 is also used as a pigment and as a precursor to other manganese compounds, such as KMnO
4. It is used as a reagent in organic synthesis, for example, for the oxidation of allylic alcohols. MnO
2 is α polymorph that can incorporate a variety of atoms in the "tunnels" or "channels" between the manganese oxide octahedra. There is considerable interest in α-MnO
2 as a possible cathode for lithium ion batteries.
Group 7, numbered by IUPAC nomenclature, is a group of elements in the periodic table. They are manganese (Mn), technetium (Tc), rhenium (Re), and bohrium (Bh). All known elements of group 7 are transition metals.
Psilomelane is a group name for hard black manganese oxides including hollandite and romanechite. Psilomelane consists of hydrous manganese oxide with variable amounts of barium and potassium. Psilomelane is erroneously, and uncommonly, known as black hematite, despite not being related to true hematite, which is an iron oxide.
The mineral group tantalite [(Fe, Mn)Ta2O6] is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2). Iron-rich tantalite is the mineral tantalite-(Fe) or ferrotantalite and manganese-rich is tantalite-(Mn) or manganotantalite.
Romanèchite ((Ba,H2O)2(Mn+4,Mn+3)5O10) is the primary constituent of psilomelane, which is a mixture of minerals. Most psilomelane is not pure romanechite, so it is incorrect to consider them synonyms. Romanèchite is a valuable ore of manganese, which is used in steelmaking and sodium battery production. It has a monoclinic crystal structure, a hardness of 6 and a specific gravity of 4.7-5. Romanèchite's structure consists of 2 × 3 tunnels formed by Mn oxide octahedra.
Galaxite, also known as 'mangan-spinel' is an isometric mineral belonging to the spinel group of oxides with the ideal chemical formula Mn2+

Pelagic sediment or pelagite is a fine-grained sediment that accumulates as the result of the settling of particles to the floor of the open ocean, far from land. These particles consist primarily of either the microscopic, calcareous or siliceous shells of phytoplankton or zooplankton; clay-size siliciclastic sediment; or some mixture of these. Trace amounts of meteoric dust and variable amounts of volcanic ash also occur within pelagic sediments. Based upon the composition of the ooze, there are three main types of pelagic sediments: siliceous oozes, calcareous oozes, and red clays.
In sedimentology and geology, a nodule is a small, irregularly rounded knot, mass, or lump of a mineral or mineral aggregate that typically has a contrasting composition, such as a pyrite nodule in coal, a chert nodule in limestone, or a phosphorite nodule in marine shale, from the enclosing sediment or sedimentary rock. Normally, a nodule has a warty or knobby surface and exists as a discrete mass within the host strata. In general, they lack any internal structure except for the preserved remnants of original bedding or fossils. Nodules are closely related to concretions and sometimes these terms are used interchangeably. Minerals that typically form nodules include calcite, chert, apatite (phosphorite), anhydrite, and pyrite.
Konongo is a gold bar mining and manganese mining community located in Ashanti, Ghana. The town serves as the capital of the Asante Akim Central Municipal. As of 2012, Konongo has a settlement population of 41,238 people. Konongo is about 53 kilometres (33 mi) from Kumasi, the Ashanti capital.
Nace is an unincorporated community in Botetourt County, Virginia, United States.
Paint Bank is an unincorporated community in northern Craig County, Virginia, United States. It is located at the intersection of State Route 18 and State Route 311 northwest of the town of New Castle, the county seat. The village is located between Potts Mountain and Peters Mountain.
Manganese is a ghost town and former mining community in the U.S. state of Minnesota that was inhabited between 1912 and 1960. It was built in Crow Wing County on the Cuyuna Iron Range in sections 23 and 28 of Wolford Township, about 2 miles (3.2 km) north of Trommald, Minnesota. After its formal dissolution, Manganese was absorbed by Wolford Township; the former town site is located between Coles Lake and Flynn Lake. First appearing in the U.S. Census of 1920 with an already dwindling population of 183, the village was abandoned by 1960.
The Delinești mine is a large mine in the west of Romania in Caraș-Severin County, 38 km east of Reșița and 448 km west of the capital, Bucharest. Delinești represents one of the largest manganese reserve in Romania having estimated reserves of 7.5 million tonnes of manganese ore grading 20% manganese metal.
The Globurău mine is a large mine in the west of Romania in Caraş-Severin County, 29 km north of Orşova and 392 km west of the capital, Bucharest. Globurău is one of the largest manganese reserves in Romania with estimated reserves of 3 million tons of manganese.
Manganese is a chemical element with symbol Mn and atomic number 25.
The Royal Land Company of Virginia was set-up in Rockingham County, Virginia, on 27 March 1876, for the purpose of purchasing and developing mineral lands, mines, and manufacturing their products. It purchased, in 1876, from private parties and corporations, the fee simple and leases of numerous tracts of coal, iron, other mineral, and timber lands in Virginia and West Virginia, aggregating 154,997.75 acres (62,725.36 ha).
