Middleback Ranges
The Middleback Range is a mountain range on the eastern side of Eyre Peninsula in South Australia. The Middleback Range has been a source of iron ore for over a century, particularly to feed the Whyalla Steelworks. Mines in the region were first developed by BHP from the 1890s and are now owned and operated by Liberty House Group. Geography The Middleback Range extends from Iron Knob at the northern end near the Eyre Highway to the Lincoln Highway, halfway between Whyalla and Cowell at its southern extent. The Ironstone Hill Conservation Park is immediately west of the southern part of the ranges. Geology The Middleback Range is part of the Cleve Subdomain of the Gawler Craton. The iron ore deposits are primarily of Early Proterozoic metasediments of the Hutchison Group. Mining All of the mines in the Middleback Range are operated as open pit mines, producing magnetite and hematite ores. Magnetite is processed at Whyalla, and hematite is exported. The mines are serviced by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Ranges Of South Australia
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations have different plants and animals. Because ...

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 ...

BHP Whyalla Tramway
The BHP Whyalla Tramway is a gauge heavy-haul railway on the Eyre Peninsula in South Australia. It runs from haematite mines at Iron Monarch, Iron Baron and Iron Duke in the Middleback Range, about west of Whyalla, to company steelworks at the coastal city of Whyalla. Opened in 1901, it was built by, and until 2000 operated by, the Broken Hill Proprietary Company (BHP). it was owned by Liberty House Group and operated on its behalf by rail operator One Rail Australia, which was sold in 2022 to Aurizon. History In 1899, BHP was granted a lease to mine iron ore from the Middleback Ranges. The ''Hummock Hill to Iron Knob Tramways and Jetties Act 1900'' authorised BHP to build a 54 kilometre line from Hummock Hill, Whyalla to Iron Knob that opened on 28 August 1901. In 1930, a branch opened from Middleton Junction to Iron Baron. The latter closed in 1947 and reopened in 1958. In 1990 it was extended 32 kilometres from Iron Baron to Iron Duke.

Hematite
Hematite (), also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of . It has the same crystal structure as corundum () and ilmenite (). With this it forms a complete solid solution at temperatures above . Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined as an important ore mineral of iron. It is electrically conductive. Hematite varieties include ''kidney ore'', ''martite'' (pseudomorphs after magnetite), ''iron rose'' and ''specularite'' (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is not only harder than pure iron, but also much more brittle. Maghemite is a polymorph of hematite (γ-) with the same chemical formula, but with a spinel structure like magnetite. Large deposits of hematite are found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetite
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe2+Fe3+2O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and leaves a black streak. Small grains of magnetite are very common in igneous and metamorphic rocks. The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ''ferrous-ferric oxide''. Properties In addition to igneous rocks, magnetite also occurs in sedimentary rocks, including banded iron formations and in lake and marine sediments ...

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 ...

Government Of South Australia
The Government of South Australia, also referred to as the South Australian Government, SA Government or more formally, His Majesty’s Government, is the Australian state democratic administrative authority of South Australia. It is modelled on the Westminster system of government, which is governed by an elected parliament. History Until 1857, the Province of South Australia was ruled by a Governor responsible to the British Crown. The Government of South Australia was formed in 1857, as prescribed in its Constitution created by the Constitution Act 1856 (an act of parliament of the then United Kingdom of Great Britain and Ireland under Queen Victoria), which created South Australia as a self-governing colony rather than being a province governed from Britain. Since the federation of Australia in 1901, South Australia has been a state of the Commonwealth of Australia, which is a constitutional monarchy, and the Constitution of Australia regulates the state of South A ...
