McArthur River Zinc Mine
The McArthur River mine is a zinc-lead mine, situated about 70 kilometres southwest of Borroloola, near the Gulf of Carpentaria in the northeastern Northern Territory, Australia. It is operated by McArthur River Mining (MRM), a subsidiary of the Swiss mining company Glencore. Although discovered in the 1950s, when it was originally called the HYC or "Here's Your Chance" deposit, it only opened as a mine in 1995. Initially an underground mining operation, the mine has been converted to open-cut. Early history The McArthur River zinc mine is based on one of the world's largest zinc, lead and silver deposits. Tom Lynott, the manager of McArthur River station is attributed with identifying the valuable metals in the area as early as 1887. Small mining ventures were attempted and failed due to the cost of transport. The deposit was proven in 1955 by a survey party from Mount Isa Mines (MIM) and named 'HYC' or 'Here’s Your Chance'. The name came out of a conversation between chie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borroloola, Northern Territory
Borroloola ( local Aboriginal languages: ''Burrulula'') is a town in the Northern Territory of Australia. It is located on the McArthur River, about 50 km upstream from the Gulf of Carpentaria. Location Borroloola lies on the traditional country of the Yanyuwa people, on the coastal plain between the Barkly Tablelands and the Gulf of Carpentaria. Rivers that run from the Tablelands escarpment to the Gulf regularly flood in the wet season, making travel on the unsealed section of Highway One along the coastal plain to Queensland impossible. The rivers of this region have carved spectacular gorges through sandstone deposits in their upper reaches. The rivers and coastal areas are host to barramundi, earning Borroloola a reputation among sports fisherman, and also to the deadly saltwater crocodile. The region has little rain from May to September and is characterised by lightly treed Savanna grasslands. History Garrwa (also known as Garawa) is a language of the Gulf regio ...

Federal Court Of Australia
The Federal Court of Australia is an Australian superior court of record which has jurisdiction to deal with most civil disputes governed by federal law (with the exception of family law matters), along with some summary (less serious) and indictable (more serious) criminal matters. Cases are heard at first instance by single judges. The court includes an appeal division referred to as the Full Court comprising three judges, the only avenue of appeal from which lies to the High Court of Australia. In the Australian court hierarchy, the Federal Court occupies a position equivalent to the supreme courts of each of the states and territories. In relation to the other courts in the federal stream, it is superior to the Federal Circuit and Family Court of Australia for all jurisdictions except family law. It was established in 1976 by the Federal Court of Australia Act. The Chief Justice of the Federal Court is James Allsop. Jurisdiction The Federal Court has no inherent jurisdicti ...

Albion Process
The Albion process is an atmospheric leaching process for processing zinc concentrate, refractory copper and refractory gold. The process is important because it is the most cost-effective method currently in use for extracting both the zinc and lead from concentrates that contain high lead levels (7% or greater). Zinc and lead often occur together and large remaining zinc deposits contain levels of lead that exceed what can be economically extracted through other techniques. The Albion process is not sensitive to the concentration grade and gives favorable recovery with both low grade and dirty concentrates. Environmental impact is also claimed to be mitigated using this technology because in contrast to other methods, sulfur dioxide is not emitted and less energy is consumed over all. History Development of the Albion process started during the early nineties led by Mount Isa Mines. It was first patented in 1993. Several pilot plant projects were conducted in 1994 and 1995 which t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc Smelting
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it. The most common zinc concentrate processed is zinc sulfide,. which is obtained by concentrating sphalerite using the froth flotation method. Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide.. Approximately 30% of all zinc produced is from recycled sources. Methods There are two methods of smelting zinc: the pyrometallurgical process and the electrolysis process. Both methods are still used. Both of these processes share the same first step: roasting. Roasting Roasting is a process of oxidizing zinc sulfide co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead (metal)
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 group, le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mineralogy
Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts. Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization. History Early writing on mineralogy, especially on gemstones, comes from ancient Babylonia, the ancient Greco-Roman world, ancient and medieval China, and Sanskrit texts from ancient India and the ancient Islamic world. Books on the subject included the ''Naturalis Historia'' of Pliny the Elder, which not only described many different minerals but also explained many of their properties, and Kitab al Jawahir (Book of Precious Stones) by Persian scientist Al-Biruni. The German Renaissance specialist Georgius Agricola wrote works such as '' De re metallica'' (''On Metals'', 1556) and ''De Natura Fossilium'' ( ...

Mount Isa Mines
Mount Isa Mines Limited ("MIM") operates the Mount Isa copper, lead, zinc and silver mines near Mount Isa, Queensland, Australia as part of the Glencore group of companies. For a brief period in 1980, MIM was Australia's largest company. It has pioneered several significant mining industry innovations, including the Isa Process copper refining technology, the Isasmelt smelting technology, and the IsaMill fine grinding technology, and it also commercialized the Jameson Cell column flotation technology. History In 1923 the orebody containing lead, zinc and silver was discovered by the miner John Campbell Miles. Mount Isa Mines Limited was one of three companies founded in 1924 to develop the minerals discovered by Miles, but production did not begin until May 1931.N Kirkman, ''Hilton Mine,'' (Mount Isa Mines Limited: Mount Isa, Queensland, 1990), 2–3. The other two companies were Mount Isa Silver Lead Proprietary and Mount Isa South. These were both acquired by MIM by late 19 ...

Ore Concentrate
Ore concentrate, dressed ore or simply concentrate is the product generally produced by metal ore mines. The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component. The concentrate is then transported to various physical or chemical processes called hydrometallurgy, pyrometallurgy smelters, and electrometallurgy where it is used to produce useful metals. Ore concentrates are classified as a hazardous cargo for shipping by the International Maritime Solid Bulk Cargoes (IMSBC) Code, which is part of the SOLAS Convention, due to their tendency under certain conditions, to liquefy, which may affect the stability of the ship due to the free surface effect potentially causing a ship to capsize Capsizing or keeling over occurs when a boat or ship is rolled on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is upside down in the water.

Dissemination
To disseminate (from lat. ''disseminare'' "scattering seeds"), in the field of communication, is to broadcast a message to the public without direct feedback from the audience. Meaning Dissemination takes on the theory of the traditional view of communication, which involves a sender and receiver. The traditional communication view point is broken down into a sender sending information, and receiver collecting the information processing it and sending information back, like a telephone line. With dissemination, only half of this communication model theory is applied. The information is sent out and received, but no reply is given. The message carrier sends out information, not to one individual, but many in a broadcasting system. An example of this transmission of information is in fields of advertising, public announcements and speeches. Another way to look at dissemination is that of which it derives from the Latin roots, the scattering of seeds. These seeds are metaph ...
