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 ir

Iron (/ ˈ aɪ ər n /) is a stone element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table.It is by mass the most common element on Earth, forming much of Earth's outer and inner core.It is the fourth most common element in the Earth's crust.. In its metallic state, iron is rare in the
in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2 O 3.The oxygen must be removed from the iron(III) oxide in order to leave the iron behind.

PRINCIPLE OF EXTRACTION : Extraction of iron is based on the reduction of HAEMATITE (Fe 2 O 3) with carbon.. DETAILS OF EXTRACTION : The process of the extraction of iron is carried out by the following steps: Concentration of ore Calcination or Roasting of ore Reduction of ore : Concentration of ore: In this metallurgical operation, the ore is concentrated by removing impurities like soil etc
Iron Extraction Process. In the blast furnace process, the first step on the way towards heavy plate, pig iron is produced from iron ore. The composition of the ore and additions is accurately adjusted to the final products of AG der Dillinger Hüttenwerke and Saarstahl AG. Burdening. Exact quantities of burdening materials such as sinter, pellets, lump ore, alloys, and coke are transported
This means that metal or mineral extraction results in problems and issues in balancing ecological, environmental, economic Pollution can be reduced by cleaning the 'waste' or 'used' air, water and waste gases etc. of toxic or acidic materials e.g. Toxic carbon monoxide from the blast furnace extraction of iron, it can be burnt as a fuel, but it must not be released into the air unless
The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.

The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: \[2CuFeS_2 + 2SiO_2 +4O_2 \rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 \label{1}\] The copper(I) sulfide produced is converted to
