Bauxite Mining In Vietnam
According to the United States Geological Survey, Vietnam is estimated to hold the world's third-largest bauxite ore reserves after Guinea and Australia. The majority of Vietnam's reserves are located in the Central Highlands ( Tây Nguyên) and have only been minimally mined. Bauxite is typically strip mined and is used to produce aluminum. According to estimates by Vietnam's Ministry of Industry and Trade, Vietnam's reserves in the Central Highlands amount to 5.4 billion tons. Despite its large reserves, Vietnam produces only 30,000 tons of bauxite per year.Bauxite and Alumina ''U.S. Geological Survey, Mineral Commodity Summaries.''

Linc Energy
Linc Energy was an Australian energy company that specialised in coal-based synthetic fuel production, as well as conventional oil and gas production. It was engaged in development and commercialisation of proprietary underground coal gasification technology. Produced gas was used for production of synthetic fuel through gas-to-liquid technology, and was also used for power generation. The company had its headquarters in Brisbane, Queensland. In April 2016 the company was placed into voluntary administration. At the second creditors meeting in May 2016 the unanimous vote was for the company to be liquidated.

State-owned Enterprise
A state-owned enterprise (SOE) is a business entity created or owned by a national or local government, either through an executive order or legislation. SOEs aim to generate profit for the government, prevent private sector monopolies, provide goods at lower prices, implement government policies, or serve remote areas where private businesses are scarce. The government typically holds full or majority ownership and oversees operations. SOEs have a distinct legal structure, with financial and developmental goals, like making services more accessible while earning profit (such as a state railway). They can be considered as government-affiliated entities designed to meet commercial and state capitalist objectives. Terminology The terminology around the term state-owned enterprise is murky. All three words in the term are challenged and subject to interpretation. First, it is debatable what the term "state" implies (e.g., it is unclear whether municipally owned corporations and ente ...

Open-pit Mines
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique that extracts rock (geology), rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral deposits can be reached using underground mining. Open-pit mining is considered one of the most dangerous industrial sector, sectors in the industrial world. It causes significant effects to miners' health, as well as damage to the ecological land and water. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used. Extraction Miners typically drill a series of test holes to locate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coal Mining
Coal mining is the process of resource extraction, extracting coal from the ground or from a mine. Coal is valued for its Energy value of coal, energy content and since the 1880s has been widely used to Electricity generation, generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a "pit", and above-ground mining structures are referred to as a "pit head". In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging, and manually extracting the coal on carts to large Open-pit mining, open-cut and Longwall mining, longwall mines. Mining at this scale requires the use of Dragline excavator, draglines, trucks, conveyors, hydraulic jacks, and shearers. The coal mining industry has a long ...

Central Highlands (Vietnam)
The Central Highlands (), South Central Highlands (), Western Highlands () or Midland Highlands () is a region located in the south central part of Vietnam. It contains the provinces of Đắk Lắk, Đắk Nông, Gia Lai, Kon Tum, and Lâm Đồng. Geography The Central Highlands are a series of plateaus bordering the lower part of Laos and northeastern Cambodia, namely Kon Tum Plateau at 500m, Kon Plông Plateau, Kon Hà Nừng Plateau, Pleiku Plateau at 800m, Mdrak Plateau at approximately 500m, Đắk Lắk Plateau at around 800m, Mơ Nông Plateau with the height of about 800–1000m, Lâm Viên Plateau of approximately 1500m and Di Linh Plateau of about 900–1000m. All of these plateaus are situated south of the Annamite Range. The Central Highlands are mostly drained by tributaries of the Mekong.

Bauxite
Bauxite () is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (), boehmite (γ-AlO(OH)), and diaspore (α-AlO(OH)), Mixture, mixed with the two iron oxides goethite (FeO(OH)) and haematite (), the aluminium Clay minerals, clay mineral kaolinite () and small amounts of anatase () and ilmenite ( or ). Bauxite appears dull in Lustre (mineralogy), luster and is reddish-brown, white, or tan. In 1821, the French people, French geologist Pierre Berthier discovered bauxite near the village of Les Baux-de-Provence, Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished Laterite, lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and ...

Underground Coal Gasification
Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an ''in-situ'' gasification process, carried out in non-mined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide. Ratios vary depending upon formation pressure, depth of coal and oxidant balance. Gas output may be combusted for electricity production. Alternatively, the gas output can be used to produce synthetic natural gas, or hydrogen and carbon monoxide can be used as a chemical feedstock for the production of fuels (e.g. diesel), fertilizer, explosives and other products. The technique can be applied to coal resources that are otherwise unprofitable or technically complicated to extract by traditional mining methods. UCG offers an alternative to conventional coal mining methods for some resour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red River (Asia)
The Red River or the Hong River (; ; Chữ Nôm: 瀧紅), also known as the ' (lit. "Main River"; Chữ Nôm: 瀧丐) in Vietnamese and the (, ') in Chinese, is a -long river that flows from Yunnan in Southwest China through northern Vietnam to the Gulf of Tonkin. According to C. Michael Hogan, the associated Red River Fault was instrumental in forming the entire South China Sea at least as early as 37 million years before present. The name red and southern position in China are associated in traditional cardinal directions. The river is relatively shallow, and carries a lot of reddish silt along its way, appearing red brown in colour. Geography The Red River begins in China's Yunnan province in the mountains south of Dali. Main headstreams Leqiu River, Xi River and Juli River confluence at Nanjian where they form the Lishe River.
