Molycorp
Neo Performance Materials (formerly Molycorp Inc.) is a Canadian mining corporation headquartered in Toronto, Ontario. The corporation was formerly traded on the New York Stock Exchange, owned the Mountain Pass rare earth mine in California. It filed for bankruptcy in June 2015 after changing competitive circumstances, declining prices on output and a 2014 restructuring. It was purchased by its largest creditor Oaktree Capital Management and was reorganized as Neo Performance Materials. History Molycorp Inc. Roots of the company dated back to 1919 when the Molybdenum Corporation of America, established as a subsidiary of the Electric Reduction Company, started molybdenum ore mining at Questa, New Mexico. In 1950, the Molybdenum Corporation of America bought the Mountain Pass mining claims, and began production in 1952. It changed its name to Molycorp in 1974. The corporation was acquired by Union Oil in 1977, which in turn became part of Chevron Corporation in 2005. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mountain Pass Rare Earth Mine
The Mountain Pass Rare Earth Mine and Processing Facility, owned by MP Materials, is an open-pit mine of rare-earth elements on the south flank of the Clark Mountain Range in California, southwest of Las Vegas, Nevada. In 2020 the mine supplied 15.8% of the world's rare-earth production. It is the only rare-earth mining and processing facility in the United States. It is the largest single known deposit of such minerals. As of 2022, work was ongoing to restore processing capabilities for domestic light rare-earth elements (LREEs) and work has been funded by the United States Department of Defense to restore processing capabilities for heavy rare-earth metals (HREEs) to alleviate supply chain risk. The mine was reported as operating in 2025. Geology The Mountain Pass deposit is in a 1.4 billion-year-old Precambrian carbonatite intruded into gneiss. It contains 8% to 12% rare-earth oxides, mostly contained in the mineral bastnäsite. Gangue minerals include calcite, barite, and ...

Molycorp Silmet
NPM Silmet AS is a rare-earth processor located in Sillamäe, Estonia. It is a subsidiary of Neo Performance Materials. History Pre-war history and World War II History of Silmet dates back to 1926 when Swedish-Norwegian ''Eestimaa Õlikonsortsium'' (; ), controlled by Marcus Wallenberg, was established to build a shale oil extraction plant in Sillamäe. For shale oil production, the consortium built a tunnel oven in 1928. However, due to the Great Depression, production halted in 1930 and was restarted only in 1936 by the reorganized consortium called ''Baltic Oil Company''. The second tunnel oven was added in 1938. The main product was gasoline. After the Soviet occupation started in 1940, the plant was nationalized according to the 30 May 1941 Moscow Agreement between the Soviet Union and Sweden. Germany invaded the Soviet Union in 1941 and the industry's infrastructure was largely destroyed by retreating Soviet forces. During the subsequent German occupation, the ...

Rare Earth Elements
The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare earths have diverse applications in electrical and electronic components, lasers, glass, magnetic materials, and industrial processes. The term "rare-earth" is a misnomer because they are not actually scarce, but historically it took a long time to isolate these elements. They are relatively plentiful in the entire Earth's crust (cerium being the 25th-most-abundant element at 68 parts per million, more abundant than copper), but in practice they are spread thinly as trace impurities, so to obtain rare earths at usable purity requires processing enormous amounts of raw ore at great expense; thus the name "rare" earths. Scandium and yttrium are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Questa, New Mexico
Questa is a village in Taos County, New Mexico, United States. The population was 1,770 at the 2010 census. The village has trails into the Rio Grande Gorge, trout fishing, and mountain lakes with trails that access the Sangre de Cristo Mountains that overlook the area. Questa is on the Enchanted Circle Scenic Byway, near the confluence of the Rio Grande and the Red River. The "Gateway to the Rio Grande del Norte Monument", its visitors can drive to an overlook of the Red River meeting the Rio Grande in the depth of the gorge. The Carson National Forest parallels Questa to the east. The Columbine Hondo Wilderness and Latir Peak Wildness are in the Carson National Forest close to Questa. With a large Hispanic population, the village economy was historically largely dependent on agriculture and income from a now-closed Chevron molybdenum mine. Many residents also commute to Taos, Red River, and Angel Fire to work in the hospitality industries there. Geography Accord ...

Pittsburg & Midway Coal Company
The Pittsburg-Weir Coalfield, also known as Weir-Pittsburg Coalfield and Cherokee Coalfield, is a coalfield located in Cherokee and Crawford counties in the southeast corner of Kansas. The first underground shaft mine was built in the region in 1874 near Scammon. Prior to that, there was scattered small-scale drift mining and surface mining of coal, but the construction of the first shaft mine ushered in an era which eventually led to as many as 290 significant mines and numerous other small ("dinky") mines in the two counties. The most active period of mining in the region was 1890-1910, and most of the coal camps were dismantled by the 1930s or 1940s. Mechanized strip mining overtook underground mining in output in 1931, and that combined with competition from eastern coal led to a demise in importance of underground mining in the region.

Unocal
Union Oil Company of California, and its holding company Unocal Corporation, together known as Unocal was a major petroleum explorer and marketer in the late 19th century, through the 20th century, and into the early 21st century. It was headquartered in El Segundo, California, United States. Unocal was involved in domestic and global energy projects. Unocal was one of the key players in the CentGas consortium, which attempted to build the Trans-Afghanistan Pipeline to run from the Caspian area, through Afghanistan, to the Indian Ocean, at a time after the Taliban siege of Kabul in 1996. On August 10, 2005, Unocal merged its entire upstream petroleum business with Chevron and became a wholly-owned subsidiary. Unocal then ceased operations as an independent company, but continues to conduct many operations as Union Oil Company of California, a Chevron company.

Mining Companies Of The United States
Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. 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, and final reclamation or restoration of the land after the mine is closed. Mining materials are often obtained from ore bodies, lodes, veins, seams, reefs, or placer deposits. The exploitation of th ...
