Rosebery, Tasmania
Rosebery is a town on the west coast of Tasmania, Australia. It is at the northern end of the West Coast Range, in the shadow of Mount Black and adjacent to the Pieman River now Lake Pieman. It lies on the Murchison Highway, 25 kilometres north-east of Zeehan and is part of the Municipality of West Coast Council. At the , Rosebery had a population of 752. The population of Rosebery declined by 22% in the years between 1996-2001. Its newer western area on the shore of Lake Pieman is known as Primrose. History Like most of the other settlements on the west coast of Tasmania, Rosebery is a mining town. In 1893, prospector Tom McDonald discovered gold in alluvial wash, along with boulders of zinc-lead sulphide in dense rainforest on the slopes of Mount Black. McDonald pegged several claims in the name of the Rosebery Prospecting Association (named after Lord Rosebery), which later became the Rosebery Gold Mining Company. The South Rosebery Mining Company was formed soon a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureau Of Meteorology
The Bureau of Meteorology (BOM or BoM) is an executive agency of the Australian Government responsible for providing weather services to Australia and surrounding areas. It was established in 1906 under the Meteorology Act, and brought together the state meteorological services that existed before then. The states officially transferred their weather recording responsibilities to the Bureau of Meteorology on 1 January 1908. History The Bureau of Meteorology was established on 1 January 1908 following the passage of the ''Meteorology Act 1906''. Prior to Federation in 1901, each colony had had its own meteorological service, with all but two colonies also having a subsection devoted to astronomy. In August 1905, federal home affairs minister Littleton Groom surveyed state governments for their willingness to cede control, finding South Australia and Victoria unwilling. However, at a ministerial conference in April 1906 the state governments agreed to transfer responsibility for m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
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, an ...

Emu Bay Railway
The Emu Bay Railway was a Tasmania, Australian railway company. The railway was significant during full operation, in that it linked the Tasmanian Government Railways system at Burnie with that at Zeehan that further linked to the Mount Lyell railway allowing connection through to Queenstown. It was listed on the Melbourne Stock Exchange. Following the closure of the Tasmanian government line at Zeehan railway station in 1960, until 1965, it operated the Melba Line on the West Coast of Tasmania following the closure of the Zeehan section until 1998. History The origins of the Emu Bay Railway can be traced back to February 1878 when the Van Diemen's Land Company opened a 71 kilometre, horse drawn wooden tramway line from Emu Bay (Burnie) to Rouse's Camp, near Waratah, to serve the Mount Bischoff tin mines. The line was surveyed by John C Climie. In 1887, the line was taken over by the Emu Bay to Mount Bischoff Railway Company and relaid with steel rails as a gauge railwa ...

Zinifex
Zinifex was an Australian company that operated lead and zinc mines, refineries and a lead smelter. It was established in April 2004, when the assets of Pasminco were spun-off. In 2008 it merged with Oxiana to form OZ Minerals. History In September 2001, Pasminco was placed in voluntary administration. Some assets were sold by administrator Ferrier Hodgson, with the remaining profitable assets spun-off to a new entity, Zinifex, which was listed on the Australian Securities Exchange (ASX) in April 2004. Assets included mines in Mount Isa and Rosebery, and smelters in Budel (The Netherlands), Clarkesville (United States), Hobart and Port Pirie. After floating on the ASX, Zinifex proved successful mainly due to the company keeping no hedges in place, and benefiting from rises in the zinc price. The share price rose from $1.80 in April 2004 to over $18 in December 2006. On 1 July 2008, Zinifex merged with Oxiana to form OZ Minerals. Operations Zinifex Limited was enga ...

Pasminco
Pasminco was an Australian mining company founded in 1988. It was placed in voluntary administration in September 2001 with its assets sold in stages until 2004 when the remaining assets were spun-off to Zinifex. History Pasminco was established in 1988 when Conzinc Riotinto of Australia and North Broken Hill Peko merged their lead and zinc operations. In May 1998 the Emu Bay Railway, which hauled trains from Pasminco's zinc mine at Rosebery to Burnie, was sold to Australian Transport Network. On 19 September 2001, Pasminco was placed in voluntary administration due to a combination of low commodities prices, high debt servicing costs, the adverse impact of a weak Australian dollar on its currency hedging position and a failure to secure appropriate financial accommodation from its financiers. In March 2002, its Broken Hill mining operations were sold to Perilya. Remaining assets including mines in Mount Isa and Rosebery, and smelters in Budel (The Netherlands), Clarkesv ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...
