Mining In Guyana
Mining in Guyana is a significant contributor to the economy owing to sizable reserves of bauxite, gold, and diamonds. Much of these resources are found in Guyana's Hilly Sand and Clay belt, a region that makes up 20% of the country. Gold In 2012, export receipts for gold amounted to US$1.5 billion, nearly half of the country's total export receipt value. All gold mined in the country must be sold to the Guyana Gold Board, and sent abroad for refining at the Royal Canadian Mint. The gold mining industry is made up of small and medium-scale operations that support as many as 12% of the population. In the 16th century, European explorers were drawn to the Guianas due to rumors of a golden city called Manoa, ruled by the golden king El Dorado. This legend instigated settling of the region, but it wasn't until the 1840s when gold was found in significant quantities. After emancipation, small-scale gold mining was undertaken by many newly-freed Afro-Guyanese, who still make up a signi ...

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 (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-brown, white, or tan. In 1821, the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and Jamaica above carbonate rocks (limestone and do ...

Linden, Guyana
Linden is the second largest city in Guyana after Georgetown, and capital of the Upper Demerara-Berbice region, located at , altitude . It was declared a town in 1970, and includes the communities of MacKenzie, Christianburg, and Wismar. It lies on the Demerara River and has a population of 27,277 as of 2012. It is primarily a bauxite mining town, containing many mines 60–90 m deep, with many other pits now in disuse. Linden is the regional capital of Upper Demerara-Berbice. The Bauxite Company Commercial bauxite mining started in Linden a hundred years ago. In 1916 the Demerara Bauxite Company Limited, known as DEMBA, a subsidiary of the Aluminum Company of Canada Limited, was established with the objective of mining, processing and selling bauxite. The site chosen for this preliminary venture was on the Demerara River, south of the capital city Georgetown. At that time there was no settlement in the area, except for the wards of Wismar, Guyana Wismar and Christianbur ...

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

British Aluminium
British Aluminium was an aluminium production company. It was originally formed as the British Aluminium Company Ltd on 7 May 1894 and was subsequently known as British Alcan Aluminium plc (1982-1996). History In the late 1880s and early 1890s, innovations in the extraction of alumina from ore (bauxite) and of converting this into aluminium by electrolysis had precipitated a drastic fall in the price of the metal. The electrolytic process required large amounts of electricity, which could be easily and cheaply provided by hydro-electric power in the Scottish Highlands. The first aluminium ingots were produced at Foyers in the highlands in 1895 with the first hydro-electric powered smelter opening in 1896 followed by two more, at Kinlochleven in 1909 and Lochaber in 1929. Unsuccessful attempts at bauxite extraction in Northern Ireland forced the company to acquire a controlling interest in Union des Bauxites of Southern France. This established source was supplemented by the ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ...

British Guiana
British Guiana was a British colony, part of the mainland British West Indies, which resides on the northern coast of South America. Since 1966 it has been known as the independent nation of Guyana. The first European to encounter Guiana was Sir Walter Raleigh, an English explorer. The Dutch were the first Europeans to settle there, starting in the early 17th century, when they founded the colonies of Essequibo and Berbice, adding Demerara in the mid-18th century. In 1796, Great Britain took over these three colonies during hostilities with the French, who had occupied the Netherlands. Britain returned control to the Batavian Republic in 1802 but captured the colonies a year later during the Napoleonic Wars. The colonies were officially ceded to the United Kingdom in 1815 and consolidated into a single colony in 1831. The colony's capital was at Georgetown (known as Stabroek prior to 1812). The economy has become more diversified since the late 19th century but has relied on r ...
