Nickel is a chemical element; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive, but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere.
Pentlandite is an iron–nickel sulfide with the chemical formula (Fe,Ni)9S8. Pentlandite has a narrow variation range in nickel to iron ratios (Ni:Fe), but it is usually described as 1:1. In some cases, this ratio is skewed by the presence of pyrrhotite inclusions. It also contains minor cobalt, usually at low levels as a fraction of weight.
The platinum-group metals (PGMs), also known as the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs), are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block.
The Sudbury Basin, also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. It is the third-largest known impact structure on Earth, as well as one of the oldest. The structure, the eroded remnant of an impact crater, was formed by the impact of an asteroid 1.849 billion years ago in the Paleoproterozoic era.
Pyrrhotite is an iron sulfide mineral with the formula Fe(1-x)S. It is a nonstoichiometric variant of FeS, the mineral known as troilite. Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic. The magnetism decreases as the iron content increases, and troilite is non-magnetic. Pyrrhotite is generally tabular and brassy/bronze in color with a metallic luster. The mineral occurs with mafic igneous rocks like norites, and may form from pyrite during metamorphic processes. Pyrrhotite is associated and mined with other sulfide minerals like pentlandite, pyrite, chalcopyrite, and magnetite, and has been found globally.
WMC Resources Limited was an Australian diversified mining company.
Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). They are used in the production of steels and alloys. The alloys impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the leading consumer of ferroalloys. The leading producers of ferroalloys in 2014 were China, South Africa, India, Russia and Kazakhstan, which accounted for 84% of the world production. World production of ferroalloys was estimated as 52.8 million tonnes in 2015.
Nickel Mines is a hamlet that is located in Bart Township, Lancaster County, Pennsylvania, United States. The zip code is 17562 and the area code is 717.
The Midcontinent Rift System (MRS) or Keweenawan Rift is a 2,000 km (1,200 mi) long geological rift in the center of the North American continent and south-central part of the North American plate. It formed when the continent's core, the North American craton, began to split apart during the Mesoproterozoic era of the Precambrian, about 1.1 billion years ago. The rift failed, leaving behind thick layers of igneous rock that are exposed in its northern reaches, but buried beneath later sedimentary formations along most of its western and eastern arms. Those arms meet at Lake Superior, which is contained within the rift valley. The lake's north shore in Ontario and Minnesota defines the northern arc of the rift. From the lake, the rift's eastern arm trends south to central lower Michigan, and possibly into Indiana, Ohio, Kentucky, Tennessee, and Alabama. The western arm runs from Lake Superior southwest through portions of Wisconsin, Minnesota, Iowa, and Nebraska to northeastern Kansas, and possibly into Oklahoma.
Edward Ching-Te Chao was one of the founders of the field of impact metamorphism, the study of the effects of meteorite impacts on the Earth's crust.
Nickel(II) chromate (NiCrO4) is an acid-soluble compound, red-brown in color, with high tolerances for heat. It and the ions that compose it have been linked to tumor formation and gene mutation, particularly to wildlife.
Despite being a mineral rich country, Cameroon has only recently begun to investigate mining on an industrial scale. Strong metal and industrial mineral prices since 2003 have encouraged companies to develop mines here. The terrain mainly consists of granite-rich ground with areas of ultramafic rocks that are sources of cobalt and nickel. There are also deposits of bauxite, gold, iron ore, nepheline syenite, and rutile. Alluvial gold is mainly mined by artisanal miners.
William Thomas Pecora II was an American geologist who served as 8th Director of the U.S. Geological Survey and later as Under Secretary of the Interior. Pecora had a successful career in both scientific and athletic spheres—he completed in fencing at the 1936 Summer Olympics, and during his lifetime was elected to both the American Academy of Arts and Sciences and the National Academy of Sciences. He was an early figure in what is now the Landsat program, and the William T. Pecora Award for remote sensing is named after him.
Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal.
James Curtis Booth was an American chemist who was the melter and refiner at the United States Mint in Philadelphia for many years.
Gay Gulch is an iron meteorite found in 1901 by miners near Dawson City, Yukon Territory, using a slice box to mine alluvial gold. They were exploiting Pliocene gravel, hence the meteorite may have fallen at that time.
The following list creates a summary of the two major producers of different minerals.
The Cerro Matoso mine in northwest of Colombia is one of the largest open-pit ferronickel mines in the world. and the largest mine of South America, containing the largest nickel reserve in Colombia. It is operated by Cerro Matoso S.A., a company that was owned by Hanna Company and the Instituto de Fomento Industrial (IFI), then by Shell, Billiton, and then the Anglo-Australian multinational BHP, since 2015 is owned by South32. There have been allegations that the mine's operations have caused heavy metal pollution affecting especially local indigenous Zenu and Afro-Descendant residents. These allegations have been rejected by Cerro Matoso on the basis of the available scientific and medical evidence. In March 2018 a Review Chamber of the Constitutional Court of Colombia ordered Cerro Matoso to pay damages to local communities. This decision was reversed partially in September 2018 by the Plenary Chamber of the Constitutional Court on the basis that it did not comply with constitutional precedent for payment of damages and noting that there was no evidence of a direct correlation between the mining operations and the alleged damages.
Millerite or nickel blende is a nickel sulfide mineral, NiS. It is brassy in colour and has an acicular habit, often forming radiating masses and furry aggregates. It can be distinguished from pentlandite by crystal habit, its duller colour, and general lack of association with pyrite or pyrrhotite.
The mining industry of Yemen is at present dominated by fossil mineral of petroleum and liquefied natural gas (LNG), and to a limited extent by extraction of dimension stone, gypsum, and refined petroleum. Reserves of metals like cobalt, copper, gold, iron ore, nickel, niobium, platinum-group metals, silver, tantalum, and zinc are awaiting exploration. Industrial minerals with identified reserves include black sands with ilmenite, monazite, rutile, and zirconium, celestine, clays, dimension stone, dolomite, feldspar, fluorite, gypsum, limestone, magnesite, perlite, pure limestone, quartz, salt, sandstone, scoria, talc, and zeolites; some of these are under exploitation.
