How does a blast furnace extract iron?
The blast furnace
- Iron(III) oxide + carbon → iron + carbon dioxide.
- In the blast furnace, it is so hot that carbon monoxide can be used, in place of carbon, to reduce the iron(III) oxide:
- iron(III) oxide + carbon monoxide → iron + carbon dioxide.
What is the reaction temperature involved in blast furnace for extraction of iron?
Reaction taking place in zone of reduction in blast furnace Carbon monoxide reduces ferric oxide to spongy iron at about 900 K.
What is the word equation for the extraction of iron from iron oxide?
Q3. Iron is extracted from iron oxide in the blast furnace. (a) The equation for one of the reactions in the blast furnace is: Fe2O3 + 3CO 2Fe + 3CO2 (i) Complete the word equation for this reaction.
What is the product of blast furnace?
Blast furnace produces Hot metal (Liquid Iron) using Iron ore, Coke, Sinter, Pellets and fluxes such as Lime-stone, Pyroxenite, Quartzite reacting with oxygen from pre heated air.
What is the reaction of blast furnace?
The reactions of the blast furnace involve 1) combustion of the fuel and its conversion into carbon monoxide, 2) reduction of the ore, and 3) formation of slag. A reaction such as FeO + CO = Fe + CO2 can occur in both the forward and backward direction under conditions existing somewhere in the blast furnace.
Which reaction takes place in blast furnace?
Reduction of iron oxides takes place.
What is the output of iron and steel industry?
Industry produced 82.68 million tons of total finished steel and 9.7 million tons of raw iron. Most iron and steel in India is produced from the iron ore.
What is the formula of slag?
The slag can generally be expressed by the formula FeSNa2S(O). Both reactions 9.5 and 9.6 are heterogeneous and endothermic in nature.
What happens in blast furnace?
In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout …
What are the reactions occurring inside the blast furnace?
Now, we can study what are the reactions occurring inside the blast furnace at different temperatures. Ferric oxide (Fe 2 O 3) is reduced Fe 3 O 4 by carbon monoxide. Fe 3 O 4 contains FeO and Fe 2 O 3. CO is reduced to carbon and oxidized CO 2.
What happens to the iron (III) oxide in a blast furnace?
In this reaction, the iron (III) oxide is reduced to iron, and the carbon is oxidised to carbon dioxide. In the blast furnace, it is so hot that carbon monoxide can be used, in place of carbon, to reduce the iron (III) oxide: iron (III) oxide + carbon monoxide → iron + carbon dioxide Fe2O3(s) + 3CO (g) → 2Fe (l) + 3CO2(g)
What is iron extraction blast furnace metallurgy?
Iron, when extracted from iron ore such as haematite containing iron (III) oxide, Fe2O3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron.
How is carbon monoxide used in a blast furnace?
In the blast furnace, it is so hot that carbon monoxide can be used, in place of carbon, to reduce the iron (III) oxide: The blast furnace is a continuous process (ie reactants are added constantly so that the reaction does not stop).
