When you ponder the origin of iron your mind likely wanders into visions of steel mills medieval-age forges or some other manufacturing process characterized by hard hands-on work and very high temperatures. But apart from being a type of metal used in various ways in human industry iron as also an element not a compound or alloy meaning that it is possible to isolate a single atom of iron. This is not true of most familiar materials for example the smallest amount of water than can still be called water includes three atoms one of them oxygen and the other two hydrogen.Get A Quote

Iron abbreviated Fe is classified as a metal not only for everyday purposes but also on the periodic table of the elements see Resources for an interactive example. This probably comes as little surprise but in fact metals outnumber nonmetals in nature by a wide margin of the 113 elements humans have discovered or created in laboratory settings 88 are classified as metals.
Iron by mass is the fourth-most-abundant element in the Earths crust. Irons total share of Earth may be considerably greater however given that the planets molten core is believed to consist chiefly of liquefied iron nickel and sulfur. When iron is extracted from the ground in mining operations it is in the form of ore which is elemental iron mixed with one or more types of rock. The most common type of iron ore is hematite but magnetite and taconite are also significant sources of this metal.
Iron rusts or corrodes very easily compared to other metals. This creates problems for engineers because at present nine-tenths of the metal that is refined includes iron.
Most of the iron mined for human use winds up in the form of steel. Steel is an alloy meaning a mixture of metals. A popular form of this product today is called carbon steel which is somewhat misleading because carbon contributes only a tiny fraction of the mass of this steel in all its forms. In the highest-carbon form of carbon steel carbon accounts for about 2 percent of the mass of the metal this figure can range down to 110th of 1 percent without the metal losing the title of carbon steel.
When judicious amounts of metals such as nickel vanadium tungsten and manganese are integrated into steel it makes an already hard substance even harder these alloy steels are therefore well-suited for inclusion in bridges cutting instruments and electrical-grid components.
A non-steel type of iron called cast iron includes a great deal of carbon by the standards of iron metalworking at least 3 to 5 percent. Cast iron is not as tough as steel but it is considerably cheaper so in moving from steel to cast iron you make the same general trade-off you do when going from prime rib to 70 percent lean hamburger.
Iron one of the most abundant elements on Earth helped give rise to entire civilizations and is the key ingredient in steel without which many of our modern structures would not be standing. The story of irons origins is astronomical and it begins with the element being born from the explosion of stars.
The origin of iron is a fascinating story that starts with a red giant a type of star. Iron is one of Earths most abundant metals and one of lifes building blocks. Humans animals and plants require the metal to sustain life.
By scientific standards the origin of iron is one of the most violent processes imaginable. A type of star known as a red giant begins to turn all of its helium into carbon and oxygen atoms. Those atoms then begin to turn into iron atoms the heaviest type of atom a star can produce. When most of a stars atoms become iron atoms it becomes what is known as a supernova. It explodes showering space with iron oxygen and carbon atoms far and wide.
Preparation After being mined iron ore is crushed into a powder. Huge magnetic drums are then used to separate iron-poor from iron-rich ore. The iron-rich ore sticks to the drums the rest falls away. The iron-rich powder is mixed with clay and made into marble-sized pellets which are then heat-hardened.
Born of these violent explosions Earths core is likely mostly molten iron and its crust is about 5 percent iron. The life on Earth also contains iron from plants to humans. The abundant metal is truly one of Earths essential building blocks.
Not all iron on the Earths surface got here with its initial planetary formation. Massive chunks of rock known as asteroids have broken apart throughout the history of our solar system sometimes through collisions with other asteroids showering down smaller chunks of rock. The meteorite fragments that came into Earths atmosphere and did not burn up in the intense heat brought more iron to the planets surface.
Though it has been an essential part of Earth since the planets inception humans did not begin producing iron into usable implements and products until about 2000 B.C. The historic period known as the Iron Age began in south-central Asia replacing what had been the key metal bronze. Civilizations learned that iron when mixed with carbon is more durable than bronze. Iron weapons also hold a sharper edge.
Iron continued as the key metal fabric in human civilization until the 1850s when innovators began to learn that if a bit more carbon was added to iron during the production process a durable yet flexible metal resulted. By the 1870s production innovations made this new metal alloy called steel more economically viable to mass produce. The demand for steel skyrocketed during the railroad boom of the 1800s because the metal was the ideal material for rail production.
Jun 05 2015nbsp018332The History of Iron. Iron is the fourth most abundant element making up more than 5 of the earths crust. The production of iron by humans started in around 2000 BC in south-west or south-central Asia. This marked the beginning of the Iron Age which saw the widespread replacement of bronze with iron for tools and weapons.
From being a crucial building block of steel to nourishing plants and helping carry oxygen in your blood iron is always busy helping sustain life on Earth.
Nov 30 2016nbsp018332Ironmaking Making Molten Iron. Iron is one of the main constituents of steel. Essentially steel is made from a combination of iron ore and carbon coal which are sourced from around the world. These two raw materials are put into a blast furnace and melted down to create molten iron.
A new model explaining this mysterious process suggests the core was created as dribs and drabs of iron percolated inward from Earths lower mantle according to a study published Oct. 6 in the .
Oct 16 2019nbsp018332The Iron Man suit that Tony Stark wears in the movies couldnt possibly be made of iron. There are a few reasons behind that namely the fact that iron is an extremely heavy and dense metal . It also rusts very easily and is not as strong as some of its own alloys such as steel.
Although many people dont think of iron as being a nutrient you might be surprised to learn that low iron is the most common nutritional deficiency in the U.S. Almost 10 of women are iron .
Billions of years ago the newborn Earth morphed from a messy ball of mixed-up rock to a perfectly layered planet with an iron core.
A new model explaining this mysterious process suggests the core was created as dribs and drabs of iron percolated inward from Earths lower mantle according to a study published Oct. 6 in the journal Nature Geoscience. The mantle is the viscous rocky layer between the crust and Earths iron core.
To confirm the model researchers recreated the conditions of the early Earth. By squeezing a tiny speck of iron and rock between two diamond-tipped anvils and then zapping the whole shebang with a laser scientists mimicked the hot temperatures and high pressures inside the young planet.
