Smelting method used in the extraction of iron - definition Smelting is the process in which ore is mixed with purifying or heat generating substance like limestone and coke, they are heated at high temperature in an enclosed furnace. The charge consists of roasted ore, coke and limestone in the approximate ratio of 12:5:3. Coke burns to give carbon monoxide which reduces the oxide ore to metal. Limestone acts …
Get PriceExtraction of Iron using blast furnace and various types of Steel: Iron ore is reduced to iron by heating them with coke (a form of carbon) in blast furnace. As mentioned earlier, common iron ores are hematite (Fe2O3) and magnetite (Fe3O4). The air blown into the bottom of the blast furnace is heated using the hot waste gases from the top. Heat energy is valuable, and it is important to ...

Coke is produced by heating ...
Get PriceEXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3. Haematite is added to the top of the furnace along with coke (i.e ...

Get PriceThe 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.
Get PriceBlast furnaces extract pure iron from the Iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C(s) + O_2(g) rightarrow 2CO(g) In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe_2O_3(s) + 3 CO(g) rightarrow 2 Fe(s) + 3 CO_2(g) Write the net chemical equation for the production of ...

Get PriceIron does not exist on the Earth as an element, but rather in the form of its oxides and sulphides in iron ore. They are the starting materials for the technical extraction of pig iron in the blast furnace. The blast furnace operates at 1900 °C in order to smelt iron from iron ore. To attain that temperature, coke (and not coal) is used as ...
Get PriceIron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3.
Get PriceIn 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...
