Melba Flats, Tasmania
Melba Flats is a railway siding on the Emu Bay Railway east of Zeehan that served as a terminus for trains carrying copper ore from the Mount Lyell Mining and Railway Company in west coast Tasmania, once the Emu Bay Railway ceased services into the Zeehan townsite. The section of line near Melba Flats was operational by December 1900. The Rosebery to Zeehan connection closed on the 14 August 1965, however the Rosebery to Melba Flats section re-opened on the 15 January 1970. The Mount Lyell company had trucks deliver the ore along the Queenstown to Zeehan road to this siding, until 1994. The Melba Flats area is the site of numerous historical workings; hand workings and hand constructed mining shafts dating back to the 1880s. Lead, zinc, silver, tin and nickel have been located in varying quantities in the area. Allegiance Mining in the 2000s investigated open pit mining of niccolite and pentlandite Pentlandite is an iron–nickel sulfide with the chemical formula . Pentl ...

Zeehan, Tasmania
Zeehan is a town on the west coast of Tasmania, Australia south-west of Burnie. It is part of the West Coast Council, along with the seaport Strahan, and neighbouring mining towns of Dundas, Rosebery and Queenstown. History The greater Zeehan area was inhabited by the indigenous Peerapper and Tommeginne clans of the North West group for over 10,000 years prior to the British colonisation of Tasmania. They were greatly coastal peoples, residing in small numbers on a diet consisting of muttonbirds, seals, swan eggs and cider gum, and constructed bark huts when strong westerly winds brought about rain and icy temperatures. European naming On 24 November 1642, Dutch explorer Abel Tasman became the first European explorer to sight and document the Heemskirk and West Coast Ranges. Tasman sailed his ships close to the coastal area which today encompasses the Southwest Conservation Area, south of Macquarie Harbour, but was unable to send a landing party ashore due to poor weat ...

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] |
Charles Whitham
Charles Whitham was the author of the oft-reprinted ''Western Tasmania: A land of Riches and Beauty'', which was a comprehensive study of the geographical features of West Coast, Tasmania and the conditions of the region in the 1920s. Early life Charles Whitham was born in India in 1873. He and his parents travelled to Tasmania in 1886. His first book was published in 1917. ''Western Tasmania'' The book was originally published in 1924 and reprinted in 1949 and in 1984. Extracts from the book were reproduced in ''The Mercury'' in the 1930s. The book is a mix of geographical and historical information about the west coast, and includes sections on Macquarie Harbour and the Mount Lyell Mining and Railway Company. Whitham had personally travelled to many of the locations and features that he described as well as to most of the peaks of the West Coast Range. His photographs in the State Library of Tasmania attest to some of the places that he had visited. It was not until th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentlandite
Pentlandite is an iron–nickel sulfide with the chemical formula . Pentlandite has a narrow variation range in Ni:Fe but it is usually described as having a Ni:Fe of 1:1. It also contains minor cobalt, usually at low levels as a fraction of weight. Pentlandite forms isometric crystals, but it is normally found in massive granular aggregates. It is brittle with a hardness of 3.5–4 and specific gravity of 4.6–5.0 and is non-magnetic. It has a yellowish bronze color. Pentlandite is the most important source of mined nickel. Name and discovery It is named after the Irish scientist Joseph Barclay Pentland (1797–1873), who first noted the mineral. Paragenesis Pentlandite is the most common terrestrial nickel sulfide. It typically forms during cooling of a sulfide melt. These sulfide melts, in turn, are typically formed during the evolution of a silicate melt. Because Ni is a chalcophile-like element, it has preference for (i.e. it "partitions into") sulfide phases. In sul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niccolite
Nickeline or niccolite is a mineral consisting primarily of nickel arsenide (NiAs). The naturally-occurring mineral contains roughly 43.9% nickel and 56.1% arsenic by mass, but composition of the mineral may vary slightly. Small quantities of sulfur, iron and cobalt are usually present, and sometimes the arsenic is largely replaced by antimony. This last forms an isomorphous series with breithauptite (nickel antimonide). Etymology and history Medieval miners looking for copper in the German Erzgebirge ("Ore Mountains") would sometimes find a red mineral, superficially resembling copper ore. Upon attempting extraction, no copper was produced, and subsequently, the miners would be afflicted with mysterious illness. They blamed a mischievous sprite of German mythology, Nickel (similar to ''Old Nick'') for besetting the copper (German: Kupfer). This German equivalent of "copper-nickel" was used as early as 1694 (other old German synonyms are ''Rotnickelkies'' and ''Arsennickel' ...

Allegiance Mining
Allegiance Mining NL (ASX:AGM) is an Australian mining company listed on the Australian Securities Exchange on 29 October 1993. Allegiance operated the Avebury nickel mine project on the west coast of Tasmania, Australia. Allegiance had an ongoing exploration effort targeting nickel sulphide deposits around the Avebury nickel project area and production was scheduled to start in 2008. Avebury was a significant nickel sulphide discovery located 8 km west of Zeehan. The mineralisation is essentially remobilised nickel sulphide (pentlandite mineral) and is of simple metallurgy, producing some of the world's highest-grade nickel sulphide concentrate. On February 21, 2023, Allegiance Mining's U.S. division filed for Chapter 11 bankruptcy protection. Takeover Offer by Zinflex On 17 December 2008, Allegiance received a bid from Ziniflex Australia Limited ("Ziniflex") at $0.90 cents per share (increased to $1.00 per share if the bid was successful).

Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Dry Port
A dry port (sometimes referred to as an inland port) is an inland intermodal terminal directly connected by road or rail to a seaport, operating as a centre for the transshipment of sea cargo to inland destinations. In addition to their role in cargo transshipment, dry ports may also include facilities for storage and consolidation of goods, maintenance for road or rail cargo carriers and customs clearance services. The location of these facilities at a dry port relieves competition for storage and customs space at the seaport itself. A dry inland port can speed up the flow of cargo between ships and major land transportation networks, creating a more central distribution point. Inland ports can improve the movement of imports and exports, moving the time-consuming sorting and processing of containers inland, away from congested seaports. Background The term inland port is used in a narrow sense in the field of transportation systems to mean a specialized facility for intermod ...

West Coast, Tasmania
The West Coast of Tasmania is mainly isolated rough country, associated with wilderness, mining and tourism. It served as the location of an early convict settlement in the early history of Van Diemen's Land, and contrasts sharply with the more developed and populous northern and eastern parts of the island state. Climate The west coast has a much cooler and wetter climate when compared to the east coast. Frequent low pressure systems hit the west coast causing heavy rain, snow, and ice. The West Coast Range blocks these systems from impacting the east, therefore making the West Coast a rain catchment with some areas receiving over of rain a year. In winter temperatures at sea level hover around , and when not raining, morning frost is common. The temperatures are much lower inland from the coast with maximums in winter often failing to surpass . Typically, the snow line in winter is around 900 metres (3000 ft), however sea level snow falls several times each winter as ...
