Three substances are needed to enable toextractionof iron from itsore.The combined mixture is called the charge:Iron ore, haematite - often contains sand with iron oxide, Fe 2 O 3. Limestone (calcium carbonate). Coke - mainly carbon. Thechargeis placed a giant chimney called a blast furnace
Blast furnacesare used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals. Rapid combustion is maintained by the current of air under pressure. A zinc-leadblast furnaceand lead-splash condenser
The blast furnace Iron is extractedfrom iron orein a huge container called a blast furnace. Iron ores such as haematite contain iron (III) oxide, Fe2O3. The oxygen must be removed from the iron
Extractionof Metals.ExtractionofIron.. Chemistry of theblast furnace().. Limestone is calcium carbonate (CaCO 3) and it is added to theblast furnaceto remove the impurities in theironore. Calcium carbonate is decomposed by heat in thefurnaceto give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates)
Iron Extraction Manufacturing Process-Blast FurnaceMethod.Ironis extracted from different ores exist in the world. Hematite (Fe 2 O 3) is reduced toironmetal in theblast furnaceunder several steps. Limestone and coke are used as other raw materials to generate heat and reducing agents
Theextraction of ironin theblast furnace. Diagram showing the carbonextraction of iron. Raw Materials:IronOre (Haematite), Coke, Limestone and Air. Explanation:IronOre, Coke and Limestone are mixed together and fed into the top of theblast furnace. Hot air is blasted into the bottom of theblast furnace; Zone 1. Coke is used as the
Smelting method used in theextraction 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 enclosedfurnace. The charge consists of roasted ore, coke and limestone in …
Blast furnacesproduce pigironfromironore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmakingblast furnacesconsist of several zones: a crucible-shaped hearth at the bottom of thefurnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from

The process of theextraction of ironis carried out by the following steps: Concentration of ore Calcination or Roasting of ore Reduction of ore : ... Theblast furnaceis a cylindrical tower like structure about 25m to 35m high. It has an outer shell of steel. Inside offurnaceis lined with fire bricks
Extracting ironfromironore using aBlast Furnace. Introduction. The common oresof ironare bothironoxides, and these can be reduced toironby heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air
Sep 04, 2012· The following process takes place inside theblast furnace: Coke is added to haematite as it acts as a reducing agent foriron(III) oxide. Carbon, which comes into contact with haematite, reduces some of theiron(III) oxide. Reductionof iron(III) oxide:iron(III) oxide + carbon -->iron+ carbon dioxide 2 Fe2CO3 (s) + 3 C (s) --> 4 Fe (l) + 3

On passing Pre heated compressed air inside thefurnace, four distinct zones are formed. a. Zone of reduction combustion: This zone lie at the bottom of theblast furnacewhere carbon burns in presence of pre heated air forming CO 2 and heat. C + O 2 → Co 2 + heat Here, the temp is maintained above 1500 0 c. This produces the energy required
Theextraction of ironfrom its ores is quite a technical process. Theironore is first roasted in air to produceiron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in ablast furnace. These materials are loaded into theblast furnacefrom the top while ablastof hot air is introduced into it from beneath via small pipes known as tuyeres
Products formedin Blast Furnace. Limestone is also decomposed to CaO which removes silicate impurity of the ore as slag. The slag is in molten state and separates out fromiron. Theironobtained fromBlast furnacecontains about 4% carbon and some other impurities. Thisironis known as pigiron
Ironoxides can come to theblast furnaceplant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2 O 3) or Magnetite (Fe 3 O 4) and theironcontent ranges from 50% to 70%. Thisironrich ore can be charged directly into a
