So why is there a good name for something that doesn't seem to exist? Because it is easy to find iron minerals in nature, often bright orange, that are not magnetite, haematite, goethite and so on, but "somehow" iron hydroxides. The tendency then is to name that.

There are four naturally occurring isotopes of iron, iron-54, iron-56, iron-57, and iron-58. Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of.

How iron is made - material, manufacture, making, history, used .

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is.

Iron processing | Britannica

Iron is allotropic—that is, it exists in different forms. Its crystal structure is either body-centred cubic (bcc) or face-centred cubic (fcc), depending on the temperature. In both crystallographic modifications, the basic configuration is a cube with iron atoms located at the corners. There is an extra atom in the centre of each cube in.

BBC - GCSE Bitesize: Making iron

Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions. Carbon is more reactive than iron, so it can push out or displace the iron from iron oxide. Here are the equations for the reaction:.
