Lipscombite
Lipscombite (Fe2+,Mn2+)(Fe3+)2(PO4)2(OH)2 is a green gray, olive green, or black. phosphate-based mineral containing iron, manganese, and iron phosphate. Lipscombite is often formed at meteorite impact sites where its crystals are microscopically small, because crystal-forming conditions of pressure and temperature are brief. In the Classification of non-silicate minerals lipscombite is in the lipscombite group, which also includes zinclipscombite. This group is within the non-silicate, category 8, anhydrous phosphates, lazulite supergroup. Discovery The mineral lipscombite was first made artificially and then found in nature. It was named after chemist William Lipscomb by the mineralogist John W. Gruner who first made it artificially. While investigating the stability relations of iron oxides small, black, shiny crystals were obtained when a spherical iron pressure-temperature vessel was contaminated with phosphorus. The x-ray powder diffraction pattern was similar to laz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phosphate Minerals
Phosphates are the naturally occurring form of the element phosphorus. In chemistry, a phosphate is an anion, salt (chemistry), salt, functional group or ester derived from a phosphoric acids and phosphates, phosphoric acid. It most commonly means orthophosphate, a Derivative (chemistry), derivative of orthophosphoric acid, phosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one proton gives the dihydrogen phosphate ion while removal of two protons gives the hydrogen phosphate ion . These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.

Iron(III) Minerals
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechanical proper ...

Zinc Minerals
Zinc is a chemical element; it has Symbol (chemistry), symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 element, group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant Abundance of elements in Earth's crust, element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, Roasting (metallurgy), roasting, and final extractive metallurgy, extraction using electricity (electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Mineralogical Association
Founded in 1958, the International Mineralogical Association (IMA) is an international group of 40 national societies. The goal is to promote the science of mineralogy and to standardize the nomenclature of the 5000 plus known mineral species. The IMA is affiliated with the International Union of Geological Sciences (IUGS). The Association supports the activities of Commissions and Working Groups involved on certain aspects of mineralogical practice and facilitates interactions among mineralogists by sponsoring and organising meetings. In particular, the IMA holds its general meeting every four years. The last meeting was scheduled in 2022 in Lyon, France.

Humboldt County, Nevada
Humboldt County is a county in the U.S. state of Nevada. As of the 2020 Census, the population was 17,285. It is a largely rural county that is sparsely populated with the only major city being Winnemucca which has a population of 8,431. Humboldt County comprises the Winnemucca, NV Micropolitan Statistical Area and serves as an important crossroads in the national transportation network. Interstate 80 travels through the southeastern corner of the county, meeting US 95 in Winnemucca that serves as a primary freight corridor between Northern Nevada and Boise, Idaho and the Interstate 84 freight corridor that links much of the Pacific Northwest. The original transcontinental railway, constructed by the Central Pacific Railroad, reached Humboldt County on September 16, 1868. The Western Pacific Railroad would reach Humboldt County by November 1909, providing two mainline rail links to California and the Eastern United States. Both railroads have since been acquired by the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valmy, Nevada
Valmy is a census-designated place in Humboldt County, Nevada, United States, named after the Battle of Valmy in France. The Lone Tree gold-mining complex is located adjacent to I-80; mining ended there in 2007, though a small gold resource remains in place there. In 2021, Nevada Gold Mines sold the mine to i-80 Gold, who hope to process ore there. The Marigold mine is located further south of I-80 and has been in production since 1989. Valmy is also home to the North Valmy Generating Station, jointly owned by NV Energy and Idaho Power. Valmy has a post office, with the ZIP code 89438. As of the 2010 census, the community had a population of 37. History Established in 1910 by the Southern Pacific Railroad as a section point, it became Valmy on March 24, 1915. The post office from Stone House, Nevada, was moved to Valmy at that time. In 1932 Eugene DiGrazia bought Valmy's gas station, store, post office and bus depot. Popular culture In August 1977 Eric Meola shot photog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphate Mineral
Phosphate minerals are minerals that contain the tetrahedrally coordinated phosphate () anion, sometimes with arsenate () and vanadate () substitutions, along with chloride (Cl−), fluoride (F−), and hydroxide (OH−) anions, that also fit into the crystal structure. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common. Applications Phosphate rock has high concentration of phosphate minerals, most commonly from the apatite group of minerals. It is the major resource mined to produce phosphate fertilizers for the agricultural industry. Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy. The production of fertilizer is the largest source responsible for minerals mined for their phosphate content. Phosphate minerals are often used to control rust, and to prevent corrosion on ferrous materials applied with ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetragonal
In crystallography, the tetragonal crystal system is one of the 7 crystal systems. Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the Cube (geometry), cube becomes a rectangular Prism (geometry), prism with a square base (''a'' by ''a'') and height (''c'', which is different from ''a''). Bravais lattices There are two tetragonal Bravais lattices: the primitive tetragonal and the body-centered tetragonal. The body-centered tetragonal lattice is equivalent to the primitive tetragonal lattice with a smaller unit cell, while the face-centered tetragonal lattice is equivalent to the body-centered tetragonal lattice with a smaller unit cell. Crystal classes The point groups that fall under this crystal system are listed below, followed by their representations in international notation, Schoenflies notation, orbifold notation, Coxeter notation and mineral examples.Hurlbut, Cornelius S.; Klein, Cornelis, 1985, ''Ma ...

Classification Of Non-silicate Minerals
This list gives an overview of the classification of non-silicate minerals and includes mostly International Mineralogical Association (IMA) recognized minerals and its groupings. This list complements the List of minerals recognized by the International Mineralogical Association series of articles and List of minerals. Rocks, ores, mineral mixtures, not IMA approved minerals, not named minerals are mostly excluded. Mostly major groups only, or groupings used by ''New Dana Classification'' and ''Mindat''. Classification of minerals Introduction The grouping of the New Dana Classification and of the mindat.org is similar only, and so this classification is an overview only. Consistency is missing too on the group name endings (group, subgroup, series) between New Dana Classification and mindat.org. Category, class and supergroup name endings are used as layout tools in the list as well. ;Abbreviations: * "*" – Mineral not IMA-approved. * "?" – IMA discredited mineral name ...
