The Step-by-Step Process of Producing Iron from

Now, first of all, pure iron is rarely available (except if one or two meteorites crash). It has to be derived from iron ore that occurs near the surface when mining. Then the iron derived after a long processing in the blast furnace is handed over to the iron and steel industry to make a huge amount of useful materials. Most of the iron, however, is used in the construction industry. In fact, the entire construction sector is

Environmental impact of iron ore mining - Wikipedia

Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH)n(H2O)) or siderite (FeCO3). Roughly 98% of iron ore on the global market is used in iron and steel production. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating, Most iro

Processes and Procedures in the Extraction of

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Iron Ore Reduction - an overview ScienceDirect

The iron-ores that are charged into the process go through fluidized bed reactors where they are heated and reduced to Direct Reduced Iron (DRI). The DRI is then charged into the melter gasifier where the final reduction and melting as well as the production of reducing gas by gasification of coal with oxygen takes place (Schenk, 2011).
