Iron ore - Wikipedia, the free encyclopedia Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. In Australia iron ore is won from three main sources; massive magnetite ore as at Savage River, Tasmania; pisolite "channel-iron" ore derived by mechanical erosion of primary banded-iron formations and accumulated in alluvial channels such at Robe River, Western Australia; and banded iron formation related ores such as at Newman, Hamersley and Koolyanobbing, Western Australia. Thus, the iron ore must be powdered and mixed with coke, to be burnt in the smelting process. en.wikipedia.org /wiki/Iron_ore   (1142 words)

Mineral Information Institute - IRON ORE The principle ores of iron are Hematite, (70% iron) and Magnetite, (72 % iron). Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. Iron and steel face continual competition with lighter materials in the motor vehicle industry; from aluminum, concrete, and wood in construction uses; and from aluminum, glass, paper, and plastics for containers. www.mii.org /Minerals/photoiron.html   (1070 words)

ironsmelt The chemical process reduces iron oxide to pure iron by heating the ore to a liguid state and having the oxide bond to the carbon of the charcoal fuel in various formations of carbon mono- and di- oxides. Smelting chemically reduces ferrous oxide--contained in ore in various chemical configurations--into iron (without the oxide), and byproduct carbon mono- and di-oxides. The chemical elements of smelting are found in iron ore (ferrous oxide), charcoal or coke (carbon), and the air blast of the furnace (oxygen). home.europa.com /~heritage/ironsmelt.html   (2605 words)

Iron ore and direct reduced iron Iron ore is primarily found as the oxides or iron, notably haematite and magnetite and hydroxides as goethite and limonite. Iron ore is negotiated on the iron content where 1 per cent of iron ore is one unit. For Rio Tinto's Hamersley Iron, which is under pressure to begin secondary processing of iron ore, HIsmelt would enable the use of lower grade (cheaper) ores to around 62 per cent iron and higher levels of phosphorous and alumina. www.chemlink.com.au /iron.htm   (3260 words)

History of the Iron Ore Trade Iron ore shipments to be moved by these early freighter was spouted on the dock and then wheeled aboard in barrows through the gangways. A ton of iron ore is moved a thousand miles on the Great Lakes for seven-tenths of a mill per mile; a ton of iron ore is carried from Duluth, Minnesota to Buffalo, New York at a rate but little in excess of the ordinary railroad switching charge in any of the large cities. The iron ore trade had an influence upon the depth of the channels and gradual evolution in the type of steamer construction, through the development of loading and unloading appliances. web.ulib.csuohio.edu /SpecColl/glihc/articles/carrhist.html   (5708 words)

LBL IRON ORE PRODUCTION By 1830, the region was the third-largest producer of iron ore in the country. This is slag, a by-product of the iron smelting process, and debris from the Center Furnace production of more than 120 years ago. Northern industrialists recognized the region's potential when they found iron ore, www.lbl.org /Iron.html   (277 words)

USGS Minerals Infromation: Statistical Compendium - IRON ORE The principal ore minerals of iron are hematite, magnetite, siderite, and goethite. The natural ores, which consisted primarily of hematite and goethite, were extracted from near-surface zones of enrichment in the Precambrian banded iron ore formations of Minnesota, Michigan, and Wisconsin. This more easily reducible type of pellet is created by adding limestone and/or dolomite to the iron ore concentrate during the balling stage. minerals.usgs.gov /minerals/pubs/commodity/iron_ore/stat   (1134 words)

The Iron Ore Market This would seem to point to a situation with continued strong demand for iron ore and a finely balanced world market over at least the next two years and possibly longer, depending on both developments in the world economy and the speed with which new capacity can be brought into production. However, iron ore producers are used to manage supply and to time capacity additions so as to match demand increases. Spot iron ore freight rates shot up and earlier unheard of levels were recorded in early 2004. r0.unctad.org /infocomm/Iron/covmar04.htm   (588 words)

Handbook of Texas Online: IRON ORE DEPOSITS Iron ore deposits of two kinds occur in Texas in two general areas: magnetic iron ores in the central mineral region and brown ores (limonite, goethite, and hematite) in northeastern Texas. Significant amounts of iron ore were received and shipped both overseas and domestically during the decade. When iron production virtually ceased in 1910, less than 700,000 long tons of ore had been processed. www.tsha.utexas.edu /handbook/online/articles/view/II/gpi1.html   (549 words)

Berkshire Taconic :: Human history :: The Colonial Iron Ore Industry Iron ore is the first ingredient needed for making iron and this region was particularly rich in hematite. Workers excavated iron ore in chunks from both open pits, such as Ore Hill in Salisbury, Connecticut and shaft mines, such as the Klondike in Richmond. The four ingredients that are essential for iron production were plentiful in the Berkshire Taconic Landscape, so the region became a center of the colonial iron industry during the 19th century. www.lastgreatplaces.org /berkshire/history/art6162.html   (586 words)

Official Alabama Mineral Iron ore mining in the state ceased in 1975 primarily owing to the availability of inexpensive higher grade imported ores. Hematite, an oxide of iron (Fe), is also known as "red iron ore" and in 1967 was designated as the State Mineral by the Alabama Legislature. In 1904 Birmingham iron ore was used in casting the statue of Vulcan, which stands atop Red Mountain as the largest cast-iron structure ever made. www.archives.state.al.us /emblems/st_miner.html   (245 words)

Howstuffworks "How Iron & Steel Work" Iron ore is simply rock that happens to contain a high concentration of iron. One thing that gave certain countries an edge between the 15th and 20th centuries was the availability of iron ore deposits. For example, England, the United States, France, Germany, Spain and Russia all have good iron ore deposits. science.howstuffworks.com /iron2.htm   (98 words)

Iron When the iron moves in and out slightly from its position, the motion is transmitted to the histidine bound to it, which moves a section of the protein that interacts with the other proteins of the hemoglobin to make the bonding of oxygen more or less favorable. Iron is the fourth most plentiful element in the earth's crust (4.6%), but is so widely disseminated that it can be obtained only from ores in which iron has been specially concentrated. Iron is the most freqently encountered metal in daily life, always in the form of manufactured objects, and usually covered with a protective coating or buried deep within the object. www.du.edu /~jcalvert/phys/iron.htm   (8748 words)

IRON ORE PROCESSING Proposal entails mining the Mt Gibson iron ore deposit which is 280 km to the south east of Geraldton which has proven reserves of 260 million tonnes of magnetite which would be adequate for a 50 year project life. For fine ore using DRI producers, the lower price of fines containing the same amount of iron represents an important potential raw material advantage for any iron ore producer capable of using those fines (of course if not incurring the cost for its pelletisation). The downside is that a relatively high grade of iron ore is required as the process retains the impurities and even some unconverted iron oxide. www.chemlink.com.au /dri.htm   (4318 words)

iron ore & taconite All of the iron ore that is mined in the UP of Michigan and in northern Minnesota is moved out of the region as taconite pellets. Although many factors contributed to the development of the iron and steel industry, it is difficult to imagine one more critical than ore carriers, given the geographic proximity of the components necessary for iron and steel production near the shores of the Great Lakes. The importance of iron in settling the Great Plains during the Gilded Age is apparent in a letter dated 28 August 1877 by Kansas homesteader Howard Ruede. www.geo.msu.edu /geo333/iron_ore__taconite.html   (2055 words)

USGS Minerals Information: Iron Ore Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe).

Taconite - Digging into MN Minerals: Minnesota DNR The iron ore is separated from the taconite using magnetism. Taconite is a low-grade iron ore. When the high-grade natural iron ore was plenitful, taconite was considered a waste rock and not used. E.W. Davis of the University of Minnesota, along with other scientists and engineers, conducted years of laboratory tests and experiments to find a way to take the iron ore out of the taconite rock. www.dnr.state.mn.us /education/geology/digging/taconite.html   (434 words)

ofwgen4 The Hittites not only developed iron smelting, but for many years they controlled the area's supply of iron ore. By producing a harder metal than copper or bronze, the Hittites helped change the tools of agriculture and the weapons of warfare. Iron ore was known long before the technology was developed for smelting it. Iron is another matter because the iron age didn't begin until about 1000 BCE, or about 2,500 years later. www.ourfathersword.org /ofwgen4.html   (4864 words)

Iron Ore Companies... NWPX produces water pipes, and they do not mine iron ore. If they use iron ore in producing pipes, that would mean higher iron ore prices would result in higher costs for NWPX which they would cut into margins unless they raise prices. High iron ore prices would only benefit miners of iron ore, not manufacturers that use iron ore in their products. The largest iron ore producer in the world, RIO, announced a minimum annual dividend of $1.43 this year. www.marketocracy.com /cgi-bin/WebObjects/Portfolio.woa/ps/ReadTopicPage/source=AoBjGcDbDpBcAmDkMaKiAbDd/from=10   (636 words)
