Minas Ragra
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 The Vanadium Corporation of America was a commercial producer of vanadium, a transition metal and a strengthening additive for steel. The company was founded in 1906 by Joseph M. Flannery and was headquartered in Pittsburgh, Pennsylvania. The comp .... 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. See also * * * * References Vanadium< ...

Vanadium
Vanadium is a chemical element with the 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. Spanish scientist Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by analyzing a new lead-bearing mineral he called "brown lead". Though he initially presumed its qualities were due to the presence of a new element, he was later erroneously convinced by French chemist Hippolyte Victor Collet-Descotils that the element was just chromium. Then in 1830, Nils Gabriel Sefström generated chlorides of vanadium, thus proving there was a new element, and named it "vanadium" after the Scandinavian goddess of beauty and fertility, Vanadís (Freyja). The name was based on the wide range of colors found in vanadium compounds. Del Rio's lead mineral was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

José J
José is a predominantly Spanish and Portuguese form of the given name Joseph. While spelled alike, this name is pronounced differently in each language: Spanish ; Portuguese (or ). In French, the name ''José'', pronounced , is an old vernacular form of Joseph, which is also in current usage as a given name. José is also commonly used as part of masculine name composites, such as José Manuel, José Maria or Antonio José, and also in female name composites like Maria José or Marie-José. The feminine written form is ''Josée'' as in French. In Netherlandic Dutch, however, ''José'' is a feminine given name and is pronounced ; it may occur as part of name composites like Marie-José or as a feminine first name in its own right; it can also be short for the name ''Josina'' and even a Dutch hypocorism of the name ''Johanna''. In England, Jose is originally a Romano-Celtic surname, and people with this family name can usually be found in, or traced to, the English county of C ...

Patrónite
Patronite is the vanadium sulfide mineral with chemical formula, formula Vanadium, Vsulfur, S4. 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. The mineral was first described in 1906 for an occurrence in the Minas Ragra vanadium mine near Junín, Cerro de Pasco, Peru. It was named for Peruvian metallurgist Antenor Rizo-Patron (1866–1948) the discoverer of the deposit. At the Type locality (geology), type locality in Peru it occurs in fissures within a red shale likely derived from an asphaltum deposit. Associated minerals include, native sulfur, bravoite, pyrite, minasragrite, stanleyite, dwornikite, quartz and vanadium bearing lignite. It has also been reported from the Yushkinite gorge on the Middle Silova-Yakha River on the Paikhoi Range of the polar Urals of Russia a ...

Vanadium Corporation Of America
The Vanadium Corporation of America was a commercial producer of vanadium, a transition metal and a strengthening additive for steel. The company was founded in 1906 by Joseph M. Flannery and was headquartered in Pittsburgh, Pennsylvania. The company operated several vanadium mines in multiple countries, including Peru. The raw material was converted into a ferroalloy at its plant in Bridgeville, Pennsylvania. By 1914, it was estimated that 75 percent of the world's vanadium ore production came from the American vanadium mine in Minas Ragra, Peru, making it one of the largest producers of the element in the world. In August 1916, James J. Flannery sold the company but remained chairman of the board. J. Leonard Replogle headed the syndicate that took over the company and became president of the new firm, which retained its original name. In 1919, the company acquired the Primos Chemical Company.
