Iron oxide is mixed with coke(Carbon) and Limestone(Calcium Carbonate).
This mixture is named 'sinter'.
It is loaded into the top of the blast furnace. Whereupon a BLAST of hot air is blown in at the bottom through 'tuyeres'. The temperature is about 1100 oC . This is a 24 hour , 7 days a week process. It does not stop unless the furnace is to be closed down for maintainance, e.g. checking the silicon brick lining, and checking the cooling water jacket is water-tight etc.,
This hot air does two things;-
#1 it combines with the coke to form carbon monoxide (CO)
#2 it thermally decomposes the limestone to calcium oxide and carbon dioxide. Because of the 'shortage' of oxygen in the furnace and an excess of coke , the carbon dioxide also decomposes to form carbon monoxide.
The carbon monoxide is a very good reducing agent and reduces the iron ore to form iron.
Fe2O3 + 3CO = 2Fe + 3CO2
The CO2 can then re-circulate to form more CO.
The calcium oxide formed from the decomposition of limestone reacts with the impurities , mainly sand (silicon dioxide) to form 'slag' (Calcium silicate ' CaSiO3).
So you have two products viz. 'pig' iron and 'slag'.
The 'pig' iron has the carbon levels adjusted in a BOS plant to make steels. and the 'slag' is used to make 'breeze' blocks for building and for road surfaces.
NB THe coke(carbon) is obtained from coal. Coal is baked in coke ovens to release the unwanted gases e.g. sulphur dioxide, ammonia, hydrogen sulphide , methane etc., to form coke. These released gases are 'captured' and sold to make other chemicals. e.g. paints, fertilizers. etc.,
Hope that helps!!!!
No, iron oxide is not an element. It is a compound of iron and oxygen. (There is more than one kind of iron oxide, too.)
Iron oxide is made up of iron and oxygen combined together. There are three types of iron oxide viz., Iron(II) oxide (FeO) occasionally referred to as 'greenstone' , because it is slightly green in colour. Iron(III) oxide (Fe2O3) commerically referred to as iron ore. It is the most common and stable of the oxides of iron. Iron(IV)Oxide (Fe3O4) known as magnetite. Because a rod or bar of it will orientate towards the north pole. Historically it was named 'lodestone'.
Iron II oxide: FeO Iron III oxide: Fe2O3
No, it is a compound of a metal and a nonmetal. Pure iron is a metal, however.
It is not an element. It is an compound made of two elements: Iron and Oxygen, FeO.
It is made of iron oxide. It is made of iron oxide.
Flint is made from iron, iron oxide, and magnesium oxide.

The scientific name for rust is iron oxide. It is made up of the elements iron and oxygen. Turning iron to iron oxide is an example of corrosion.

Iron oxide is a chemical compound made of iron and oxygen. It exists in two main forms: Fe2O3 (iron(III) oxide, or hematite) and Fe3O4 (iron(II,III) oxide, or magnetite).
Iron II oxide: FeO Iron III oxide: Fe2O3
To make iron sulfate, mix iron oxide with sulfuric acid. For iron hydroxide, mix iron sulfate with a strong base like sodium hydroxide to precipitate out the iron hydroxide. Iron oxide can be made by heating iron metal in the presence of oxygen.
Since iron oxide is made from TWO elements (Fe, and O), it is a compounds and so you have a MOLECULE, not an atom of iron oxide.
