Savage River, Tasmania
Savage River is a small Australian mining village located on the west coast of Tasmania. History Government surveyor Charles Sprent discovered Savage River's iron ore deposits in 1877, however the minerals were left untouched for nearly a century due to the difficulty in extracting iron from the low-quality ore. Several surveys were conducted in the interim including one in 1926 by Australian Iron & Steel. The township at Savage River was constructed from 1965 to 1967 when Roy Hudson's Industrial and Mining Investigations Pty Ltd received backing to construct a mining project in the area.Travel: Savage River '' Sydney Morning Herald'', 14 January 2008.

Port Latta, Tasmania
Port Latta is a locality in North West Tasmania, with a processing plant and port used to export iron ore from the Savage River, Tasmania, Savage River mine. Ore is transported from mine to port by a slurry pipeline, which is 85 km long and paralleled by Pipeline Road. After de-watering, the ore is loaded onto ships via conveyor belts. The capacity of the mine, pipeline and conveyor belt is about 2.4MTpa. The mine and port opened in 1967, and was still operating in 2021 with an expected life of mine to 2035 as per their 2020 yearly report.

Slurry Pipeline
A slurry pipeline is a specially engineered pipeline used to move ores, such as coal or iron, or mining waste, called tailings, over long distances. A mixture of the ore concentrate and water, called slurry, is pumped to its destination and the water is filtered out. Due to the abrasive properties of slurry, the pipelines can be lined with high-density polyethylene (HDPE), or manufactured completely from HDPE Pipe, although this requires a very thick pipe wall. Slurry pipelines are used as an alternative to railroad transportation when mines are located in remote, inaccessible areas. Canadian researchers at the University of Alberta are investigating the use of slurry pipelines to move agricultural and forestry wastes from dispersed sources to centralized biofuel plants. Over distances of 100 kilometres pipeline transport of biomass can be viable provided it is used in processes that can accept very wet feedstocks such as hydrothermal liquefaction or ethanol fermentation.

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 ...

Tailings
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe) or siderite (, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the ''Financial Times'' quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except perhaps oil". Sources Metallic iron is virtually unknown on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-pit Mining
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 ea ...

Australian Iron & Steel
Australian Iron & Steel was an Australian iron and steel manufacturer. History Public company (1928-1935) Australian Iron & Steel (AI&S) was established in 1928 to take over the business of Hoskins Iron & Steel. That company had already commenced the work to replace its two blast furnaces at Lithgow with a new one at Port Kembla. However, it needed more funding to relocate its steelmaking and rolling operations to the coast at Port Kembla. The ordinary shares in the new company were held by the former shareholders of Hoskins Iron and Steel (the Hoskins family), Dorman Long and Baldwins Lid (two British companies) and Howard Smith Limited (an Australian coal and shipping company). There were also preference shareholders, who received preference shares paying 7.5%. Only Howard Smith and the preference shareholders paid cash for their shares. Hoskins and Dorman Long received their shares in exchange for assets that they contributed to the new company. Baldwins received their ...

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 ...
