Mar 07, 2010· What is the chemical equation for making iron from its ore? Follow . 3 answers 3. ... Most of this is not chemical reactions as much as physical processes. The preparation of Coke uses heat to drive off all of the volatile compounds in the coal, leaving just elemental Carbon. ... There are two steps to iron extraction from iron oxide (iron ore ...
In the blast furnace, there are several chemical reactions taking place; that eventually result in the desired product (iron) being extracted. The coke (carbon) burns with oxygen to produce carbon dioxide. This reaction is exothermic. The CO 2 then reacts with more coke to give carbon monoxide.
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. The process involves the crushing and washing of ore.
Describe the essential reactions in the extraction of iron in the blast furnace. One chemical breaks down into two or more new chemicals. Calcium carbonate > calcium oxide + carbon dioxide CaCO3(s) > CaO(s) + CO2(g)
Oct 23, 2015· iGCSE / GCSE Chemistry: Extraction of iron () ... 6 Chemical Reactions That Changed History ... Describe the essential reactions in the extraction of iron in the blast furnace ...
This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke ...
This page is about chemical reactions involved in the iron processing, click here to get more infomation about chemical reactions involved in the iron processing. ... The Step by Step Process of Extracting Iron from its Ore using the Blast Furnace with details of Chemical Reactions. Question Answers based on the process of ex ... of the atoms ...
Jun 19, 2009· Iron ore contains oxygen atoms bonded with iron atoms (this can differ depending on which time of rock the iron ore originates from, see links). Therefore, let us assume it has one oxygen and one iron atom each to create an iron ore molecule; the word equation for this would be: Iron Ore > Oxygen + Iron +
in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2 O oxygen must be removed from the iron(III) oxide in order to leave the iron behind.
The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke.
Roughly 98% of iron ore on the global market is used in iron and steel production. Mining and processing. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating,,. Most iron ore is produced from openpit mines. After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing ...
This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the .
Get an answer for ''What is the equation of the exothermic reaction in a blast furnace?'' and find homework help for other Chemistry questions at eNotes ... pure iron from its ore, the following ...
How to extract iron from its ore The method Three substances are needed to enable to extraction of iron from its ore. The combined mixture is called the charge: Iron ore, haematite often contains sand with iron oxide, Fe2O3. Limestone (calcium carbonate). Coke mainly carbon. The charge is placed a giant chimney called a blast furnace. The blast furnace is around 30 metres high and lined ...
The production of iron from its ore involves an oxidationreduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides.
Chemical separation of impurity elements, such as silicon, aluminum, and sulfur, from iron ores often occurs in the processing to remove phosphorus from the ore. The treatments may include caustic or acid leaching of the ore, with or without a heating treatment, and .
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
The process of extraction of iron starts with the burning of carbon because of the hot air blasted in the furnace. The chemical reactions are as it follows below: C + O2 > CO2 (gas) + heat
Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction .
Coke, limestone flux, and iron ore (iron oxide) are charged into the top of the furnace in a precise filling order which helps control gas flow and the chemical reactions inside the furnace. Four "uptakes" allow the hot, dirty gas high in carbon monoxide content to exit the furnace throat, while "bleeder valves" protect the top of the furnace ...
Extraction of Metals. Extraction of Iron.. Chemistry of the blast furnace ().. Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates). ...
Oct 11, 2009· Iron ore can be found all over the world, in the form of rocks and other minerals. To be economically viable for mining, iron ore must contain at least 20% iron.
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.
Mar 07, 2010· The conversion of the Iron ore to the metallic Iron is a chemical reduction, but depends upon the chemical nature of the ore being used, for example: 2 Fe2O3 + 3 C (as coke) > 4 Fe + 3 CO2 (g) This is actually a series of reactions that are temperature dependent. 3 Fe2O3 + CO > CO2 + 2 Fe3O4 (Begins at 850° F) Fe3O4 + CO > CO2 + 3 FeO ...
