Ongi River
The Ongi River ( mn, Онги гол, zh, 翁金河, 翁金高勒) flows from the southeastern slopes of the Khangai Mountains in Övörkhangai Province for through the endorheic Ongi River Basin in Mongolia and through the aimag capital Arvaikheer. In some particularly wet years, it used to empty into Ulaan Lake in north central Ömnögovi Province, in most years it dries up earlier. In recent years it has been additionally threatened by 37 mining operations within the basin, but successful pressure by Tsetsgeegiin Mönkhbayar and the Ongi River Basin Movement helped convince 35 of the operations to cease explorations and harmful activities in the region. The water and groundwater in this area may be contaminated with mercury and cyanide from the mining industry.Lovgren S. 2008. ‘Mongolia gold rush destroying rivers, nomadic lives.

Khangai Mountains
The Khangai Mountains ( mn, Хангайн нуруу, Hangain nuruu, ); form a mountain range, range in central Mongolia, some west of Ulaanbaatar. Name Two provinces of Mongolia are named after the Khangai mountains: Arkhangai (North Khangai) and Ovorkhangai (South Khangai). The mild climate area where the two provinces meet (in eastern Khangai) is known as the cradle of Mongolian and nomadic civilization. The plains at the foot of the eastern Khangai host the Orkhon Valley, Orkhon Valley World Heritage Site. The Xiongnu capital Luut Khot (Lungcheng), the Xianbei state, Xianbei capital Ordo and the Rouran capital Moomt (Mume) are said to have been located there. Later empires also established their capitals there: e.g. the Uyghur Khaganate (745–840) built their capital Ordu-Baliq in the region. Features The tallest mountain is Otgontenger ( "Youngest sky"), which is about 4,000 metres tall. It is revered by the Mongols and state ceremonies are held there. Suvraga Khairkha ...

Endorheic Basin
An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic. Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas. Etymology The term was borrowed from French ''endor(rh)éisme'', coined from the combining form ''endo-'' (from grc, ἔνδον ''éndon'' 'wit ...

Mongolia
Mongolia; Mongolian script: , , ; lit. "Mongol Nation" or "State of Mongolia" () is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of , with a population of just 3.3 million, making it the world's most sparsely populated sovereign nation. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population. The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous land empire in history. His grandson Kublai Khan conquered China proper and established the Yuan dynasty.

Ömnögovi Province
Ömnögovi ( mn, Өмнөговь ''Ömnögovǐ'', ''South Gobi'') is an aimag (province) of Mongolia, located in the south of the country, in the Gobi Desert. Ömnögovi is Mongolia's largest aimag. The capital is Dalanzadgad. The province is rich in mineral deposits, including gold and copper. Agriculture is of minor importance. Vegetables are grown in some oases, e.g. in Dal near Dalanzadgad. As the aimag has various sights to offer, tourism is gaining importance. Ömnögovi includes several well known tourist areas, including the Flaming Cliffs, Gobi Gurvansaikhan National Park and Khongoryn Els - The Singing Sand Dunes.

Tsetsgeegiin Mönkhbayar
Tsetsgeegiin Mönkhbayar ( mn, Цэцгээгийн Мөнхбаяр) is a Mongolian herdsman and environmental activist. Mönkhbayar was elected to chair the local citizens' council in the Ongi River region 1996, after actively participating in meetings for some time. In 2001 he co-founded the Ongi River Movement, which eventually led to establishment of the Mongolian Nature Protection Coalition uniting 11 Mongolian river movements. After 1990, more than 30 companies were licensed to mine for gold on the Ongi River and its tributaries. Illegal mining practises and weak law enforcement resulted in contamination and depletion of the river. With the Ongi River Movement, Mönkhbayar convinced the Mongolian Government and Parliament to pass and enforce more restrictive laws in 2006. Erel Mining Company was shut down, and the other mining businesses were forced to use more sustainable methods. This has led to a significant improvement of the quality and amount of water in the river. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury (element)
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( ) from the Greek words, ''hydor'' (water) and ''argyros'' (silver). A heavy, silvery d-block A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-blo ... element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...

Cyanide
Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many different forms. In chemistry, a cyanide () is a chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic cyanides, the cyanide group is present as the anion . Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the group is linked by a covalent bond to carbon. For example, in acetonitrile (), the cyanide group is bonded to methyl (). Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus rather toxic. Bonding The cyanide ion is isoelectronic with carbon monoxide a ...

Mining Industry
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, and ...
