Risdon Zinc Works
Risdon Zinc Works (trading as Nyrstar Hobart) is a major zinc refinery located in Lutana, a suburb of Hobart, Tasmania, Australia. The smelter is one of the world’s largest in terms of production volume, producing over annually of high-grade zinc, primarily as die-cast alloys and continuous galvanising-grade alloys. These products are exported for global markets and utilised in a wide range of industries and products, from building and infrastructure to transportation, business equipment, communications, electronics, and consumer goods. The facility produces zinc using the Roast, Leach, Electrowinning (RLE) method, creating leach byproducts, including cadmium, gypsum, copper sulphate, lead sulphate, sulphuric acid, paragoethite and leach concentrate. The refinery has been owned and operated by the global multi-metals business Nyrstar since 2007. Nyrstar Hobart works closely with the Nyrstar Port Pirie multi-metals smelter in South Australia. The facility is Tasmania's larges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Mercury (Hobart)
''The'' ''Mercury'' is a daily newspaper, published in Hobart, Tasmania, Australia, by Davies Brothers Pty Ltd (DBL), a subsidiary of News Corp Australia, itself a subsidiary of News Corp. The weekend issues of the paper are called ''Mercury on Saturday '' and ''Sunday Tasmanian''. The current editor of ''The'' ''Mercury'' is Craig Warhurst. History The newspaper was started on 5 July 1854 by George Auber Jones and John Davies. Two months subsequently (13 September 1854) John Davies became the sole owner. It was then published twice weekly and known as the ''Hobarton Mercury''. It rapidly expanded, absorbing its rivals, and became a daily newspaper in 1858 under the lengthy title ''The Hobart Town Daily Mercury''. In 1860 the masthead was reduced to ''The Mercury'' and in 2006 it was further shortened to simply ''Mercury''.

Williamsford, Tasmania
Williamsford, Tasmania is the location of a former mining community, south of Rosebery, Tasmania and on the western lower reaches of Mount Read. It was formerly reached by the North East Dundas Tramway a line which operated between 1896 and 1929. It was also the location of the Hercules Haulage - a 2-foot gauge haulage line on the western slope of Mount Read, and the later Rosebery - Williamsford Aerial Ropeway. The town had an Australian rules team in the Rosebery Football Association until the competition disbanded in 1963. In 1924, Charles Whitham wrote:- Williamsford is the township attached to Mount Read, and is right at the foot of the steepest and longest haulage line we have... 5 miles from Rosbery by road, and 18 miles from Zeehan by tramway, and if you like rugged and wild scenery you will find it a charming place By the late twentieth century there were no longer inhabitants of this community. The townsite is to become the new site of a collection of conife ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
EZ Industries
EZ Industries, formerly the Electrolytic Zinc Company, was a zinc miner and refiner in Australia. History EZ Industries was established in 1916 by Amalgamated Zinc as the Electrolytic Zinc Company to operate the Risdon Zinc Works on the banks of the Derwent River in Risdon, Tasmania. It was renamed EZ Industries in February 1957. In 1967, EZ purchased the Emu Bay Railway. In February 1983, EZ opened the Elura Nine near Cobar, New South Wales. It built a 45 kilometre railway line to connect with the Main Western railway line to move zinc to Newcastle for shipping to Risdon. In 1984, EZ was taken over by North Broken Hill Peko. EZ owned a 31% stake in the Ranger Uranium Mine through its Energy Resources of Australia Energy Resources of Australia Ltd () is a public company based in Australia.

First World War
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 Ferdina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrolytic Zinc Company Works At Risdon On The Derwent River, December 1921 (11661266494)
An electrolyte is a medium containing ions that is electrically conducting through the movement of those ions, but not conducting electrons. This includes most soluble salts, acids, and bases dissolved in a polar solvent, such as water. Upon dissolving, the substance separates into cations and anions, which disperse uniformly throughout the solvent. Solid-state electrolytes also exist. In medicine and sometimes in chemistry, the term electrolyte refers to the substance that is dissolved. Electrically, such a solution is neutral. If an electric potential is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons. The movement of anions and cations in opposite directions within the solution amounts to a current. Some gases, such as hydrogen chloride (HCl), under conditions of high temperature or low pressure can also function as electrolytes. ...

Great Lake, Tasmania
The Great Lake, officially yingina / Great Lake, is a natural lake and man-made reservoir that is located in the central northern region of Tasmania, Australia. Location and features Fed by the Pine Rivulet and Breton Rivulet, the original natural freshwater lake, much smaller in size than its current surface area, was expanded as a result of the 1922 construction of Miena Dam #2 at its southern outflow into the Shannon River. This dam is considered to be of high heritage value by Engineers Australia. Miena Dam #2 created the once-famous ''Shannon Rise'', in the 500-metre section of the Shannon River between the dam and Shannon Lagoon. The hatching of thousands of caddis moths in early summer, attracted large numbers of trout and fishermen. In 1967, a sloping-core rock-fill dam was built just downstream of Miena Dam #2 to increase the maximum-capacity level, destroying the ''Shannon Rise''. It was raised a further in 1982, causing Miena Dam #2 to be periodically submerg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcium Carbide
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of Ca C2. Its main use industrially is in the production of acetylene and calcium cyanamide. The pure material is colorless, while pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC2 (the rest is CaO (calcium oxide), Ca3P2 (calcium phosphide), CaS (calcium sulfide), Ca3N2 (calcium nitride), SiC (silicon carbide), etc.). In the presence of trace moisture, technical-grade calcium carbide emits an unpleasant odor reminiscent of garlic. Applications of calcium carbide include manufacture of acetylene gas, generation of acetylene in carbide lamps, manufacture of chemicals for fertilizer, and steelmaking. Production Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately . This is an endothermic reaction requiring per mole and high temperatures to drive off the carbon monoxide. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrona, Tasmania
Electrona is a rural residential locality in the local government area (LGA) of Kingborough in the Hobart LGA region of Tasmania. The locality is about south of the town of Kingston. The 2016 census recorded a population of 364 for the state suburb of Electrona. Electrona is also part of the Greater Hobart statistical area. It is a small residential area on the d'Entrecasteaux Channel in Southern Tasmania. It grew up around the Electrona Carbide Works which were established in 1909. History Electrona was gazetted as a locality in 1965. It is believed that the name was derived from the fact that a company making carbide, the first electrolytic industry in Tasmania, was on this site. Around 1908, James Gillies began negotiations with the State government to permit the construction of a Hydroelectric Power Scheme at Tasmania's Great Lake, for the purpose of providing power for his newly patented zinc smelting process and a calcium carbide factory. Construction of the factory c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
