Oyu Tolgoi
The Oyu Tolgoi mine, also (, ; "Turquoise Hill"), is a combined open pit and underground mining project in Khanbogd sum within the south Gobi Desert, approximately east of the Ömnögovi Province capital Dalanzadgad. The site was discovered in 2001 and is being developed as a joint venture between Turquoise Hill Resources (a majority owned subsidiary of Rio Tinto) with 66% ownership and the Government of Mongolia with 34%. The mine began construction as of 2010 and shipped its first batch of copper on 9 July 2013. The Oyu Tolgoi mining project is the largest financial undertaking in Mongolia's history and is expected upon completion to produce of copper annually. Financing for the project has come in part from the Rio Tinto Group and an investment agreement between Ivanhoe Mines and the government of Mongolia. Rio Tinto reached an agreement with the government in January 2022 to move the joint Oyu Tolgoi copper and gold project forward and resolve outstanding issues, ...

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The Atom, atoms are linked in a continuous framework of SiO4 silicon–oxygen Tetrahedral molecular geometry, tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of Silicon dioxide, SiO2. Quartz is, therefore, classified structurally as a Silicate mineral#Tectosilicates, framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era during the Phanerozoic eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago ( Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of life on land occurred during the Devonian, as free- sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants ( pteridospermatophytes) appeared. This rapid evolution and colonization process, which had begun during the Silurian, is known as the Silurian-Devonian Terrestrial Rev ...

Molybdenum
Molybdenum is a chemical element; it has Symbol (chemistry), symbol Mo (from Neo-Latin ''molybdaenum'') and atomic number 42. The name derived from Ancient Greek ', meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a Native metal, free metal on Earth; in its minerals, it is found only in oxidation state, oxidized states. The free element, a silvery metal with a grey cast, has the List of elements by melting point, sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of the world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Most molybdenum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People's Republic Of China – Mongolia Relations
People's, branded as ''People's ViennaLine'' until May 2018, and legally ''Altenrhein Luftfahrt GmbH'', is an Austro-Swiss airline headquartered in Vienna, Austria. It operates scheduled and charter passenger flights mainly from its base at St. Gallen-Altenrhein Airport in Switzerland. History Founded as People's Viennaline in 2010, the first revenue flight of the company took place on 27 March 2011. For several years, People's only operated a single scheduled route between its St. Gallen and Vienna. However, the route network has since been expanded with some seasonal and charter services. In November 2016, People's inaugurated the world's shortest international jet route (and, after St. Maarten-Anguilla, second shortest international route overall). The flight from St. Gallen-Altenrhein Airport, Switzerland, to Friedrichshafen Airport, Germany, took only eight minutes of flight over Lake Constance and could have been booked individually. The airline faced severe criticism f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drilling Rig
A drilling rig is an integrated system that Drilling, drills wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called auger (drill), augers. Drilling rigs can sample subsurface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called 'offshore oil rigs' even if they don't contain a drilling rig). The term "rig" therefore generally refers to the complex equipment that is used to penetrate the surface of the Earth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploration Diamond Drilling
Exploration diamond drilling is used in the mining industry to probe the contents of known ore deposits and potential sites. By withdrawing a small diameter core of rock from the orebody, geologists can analyze the core by chemical assay and conduct petrologic, structural, and mineralogical studies of the rock. It is also often used in the geotechnical engineering industry for foundation testing in conjunction with soil sampling methods. The technique is named for the diamond encrusted drill bit used. History Rodolphe Leschot is often cited as being the inventor of the first core bit in 1863. Early diamond drilling opened up many new areas for mineral mining, and was related to a boom in mineral exploration in remote locations. Before the invention of the portable diamond drill, most mineral prospecting was limited to finding outcrops at the surface and hand digging. In the late 1970s, General Electric pioneered the technology of polycrystalline diamond compacts (PDCs) as a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
