Mount Keith, Western Australia
Mount Keith Mine is an open pit nickel mine in Western Australia. It is operated by BHP. The site's closest landmark is the town of Wiluna, to the north. Overview The mine is located on the north end of the long Norseman- Wiluna Greenstone belt, with nickel sulfide deposits of the dyke-like or sill deposit type. The important known nickel deposits are in the ultramafic rocks of the lower cycle, around 2700 Ma old. In 1971, the mine was thought to be able to provide 10% of the world's demand for nickel; in 1992 it was estimated as containing 270 million tons of sulfide ore, grading 0.6% nickel, enough for about twenty years. Previously owned by WMC Resources Limited, which commissioned the mine in 1995, it was acquired by BHP in June 2005. In 2009, BHP reduced the mine's activity, laying off 300 employees. Production Mount Keith is part of BHP's Nickel West operations, which includes, apart from Mount Keith, the Leinster Nickel Mine, the Kambalda Nickel Concentrator, ...

Wiluna, Western Australia
Wiluna is a small town in the Mid West region of Western Australia. It is situated on the edge of the Western Desert at the gateway to the Canning Stock Route and Gunbarrel Highway. It is the service centre of the local area for the local Martu people, the pastoral industry, the Wiluna Gold Mine, and many more people who work on other mines in the area on a " fly-in/fly-out" basis. Wiluna's climate is hot and dry, with an annual rainfall of . Mean maximum temperatures range from 19 °C (66 °F) in July, to 38 °C (100 °F) in January. The closest service centre is in Meekatharra. Overview Wiluna has from 200 to 600 Aboriginal people living within its community, depending upon the nature, time and place of the traditional law ceremonies across the Central Desert region. The traditional Aboriginal owners (a grouping known as the Martu) were "settled" as a consequence of the British colonisation process that began in the 1800s. In the 1950s a church- ...

Megaannum
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the mean yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Mines In Australia
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces ...

Nickel Mines In Western Australia
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] |

Ravensthorpe Nickel Mine
The Ravensthorpe Nickel Mine is a nickel mine and hydrometallurgical processing plant located at Bandalup Hill, east of Ravensthorpe, Western Australia. Built by BHP Billiton, it was closed in January 2009, after less than a year of operation due to a collapse in the price of nickel. It was sold in December 2009 to First Quantum Minerals who reopened the mine in December 2011, after 18 months of modifications and re-commissioning. Following a period of low nickel prices, the operation was placed on care and maintenance in October 2017. Production recommenced in January 2020 with POSCO purchasing a 30% shareholding in May 2021. History Mining in Ravensthorpe considerably predates the current nickel mine, with gold discoveries dating back to 1898. The town experienced a down turn after World War I but mining for copper continued up until the 1970s. A railway line connected Ravensthorpe with the port of Hopetoun from 1901 to 1925, when the line was closed. BHP Billiton commence ...

Leinster Nickel Mine
Leinster ( ; ga, Laighin or ) is one of the provinces of Ireland, situated in the southeast and east of Ireland. The province comprises the ancient Kingdoms of Meath, Leinster and Osraige. Following the 12th-century Norman invasion of Ireland, the historic "fifths" of Leinster and Meath gradually merged, mainly due to the impact of the Pale, which straddled both, thereby forming the present-day province of Leinster. The ancient kingdoms were shired into a number of counties for administrative and judicial purposes. In later centuries, local government legislation has prompted further sub-division of the historic counties. Leinster has no official function for local-government purposes. However, it is an officially recognised subdivision of Ireland and is listed on ISO 3166-2 as one of the four provinces of Ireland. "IE-L" is attributed to Leinster as its ''country sub-division'' code. Leinster had a population of 2,858,501 according to the preliminary results of the 202 ...

WMC Resources Limited
WMC Resources Limited was an Australian diversified mining company. History Western Mining Corporation (WMC) was formed in 1933, when William Robinson, the Australian-born London-based managing director of Broken Hill Associated Smelters, was able to interest several large London-based mining companies into forming syndicates to develop gold mines in Australia. WMC's strategy was to use the newly emerging sciences of mining geology and related geochemistry and geophysics to find new gold deposits. It was a company based on the idea that if they applied good science to exploration, they would be successful. WMC began operations in Western Australia in December 1933 when it commenced an extensive aerial survey of the Eastern Goldfields. It acquired its first profitable mining operation in June 1935 when it took an option over a new gold discovery at Cox's Find, 43 miles northwest of Laverton. WMC pioneered district-scale aerial photography in the 1930s, flying many areas in W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfide
Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S2− or a compound containing one or more S2− ions. Solutions of sulfide salts are corrosive. ''Sulfide'' also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide. Hydrogen sulfide (H2S) and bisulfide (SH−) are the conjugate acids of sulfide. Chemical properties The sulfide ion, S2−, does not exist in aqueous alkaline solutions of Na2S. Instead sulfide converts to hydrosulfide: :S2− + H2O → SH− + OH− Upon treatment with an acid, sulfide salts convert to hydrogen sulfide: :S2− + H+ → SH− :SH− + H+ → H2S Oxidation of sulfide is a complicated process. Depending on the conditions, the oxidation can produce elemental sulfur, polysulfides, polythionates, sulfite, or sulfate. Metal sulfides react with halogens, forming sulfur and metal salts. :8 MgS + 8 I2 → S8 + 8 M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Far Eastern Economic Review
The ''Far Eastern Economic Review'' (''FEER'') was an Asian business magazine published between 1946 and December 2009 in the English language.
