King Island (Tasmania)
King Island is an island in the Bass Strait, belonging to the Australian state of Tasmania. It is the largest of three islands known as the New Year Group, and the second-largest island in Bass Strait (after Flinders Island). The island's population at the was 1,585 people, up from 1,566 in 2011. The local government area of the island is the King Island Council. The island forms part of the official land divide between the Great Australian Bight and Bass Strait, off the north-western tip of Tasmania and about halfway to the mainland state of Victoria. The southernmost point is Stokes Point and the northernmost point is Cape Wickham. There are three small islands immediately offshore: New Year Island and Christmas Island situated to the northwest, and a smaller island Councillor Island to the east, opposite Sea Elephant Beach. King Island was first visited by Europeans in the late 18th century. It was named after Philip Gidley King, Colonial Governor of New South Wales, who ...

Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...

Open Pit
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting eac ...

Mining In Australia
Mining in Australia has long been a significant primary sector industry and contributor to the Australian economy by providing export income, royalty payments and employment. Historically, mining booms have also encouraged population growth via immigration to Australia, particularly the gold rushes of the 1850s. Many different ores, gems and minerals have been mined in the past and a wide variety are still mined throughout the country. Production overview In 2019, Australia was the world's largest producer of iron ore and bauxite; the second largest of gold, manganese, and lead; the third largest of zinc, cobalt, and uranium; the fifth largest of salt; the sixth largest of copper and nickel; the eighth largest producer of silver and tin; the fourteenth largest of phosphate; and the fifteenth largest of sulfur. The country is also a major producer of precious stones. Australia is the world's largest producer of opal and is one of the largest producers of diamond, ruby, sapphi ...

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 ...
