Using a steelmaking furnace. 1.Hot metal obtained from blast furnace (hot pig iron). 2.O2 reacts with carbon in pig iron. 3.Produces CO2 & CO and escapes from metal. 4.Enough O2 is used to achieve steel with desired carbon content. Using an electric arc furnace. 1.Same as steelmaking furnace. 2. Furnace charged with a mixture of metal & lime. 3.
The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace. A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron…
EXTRACTION 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 ...
Start studying The Blast Furnace and extraction of Iron from its Iron Ore. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Iron is displaced from its ore (haematite) by carbon (from coke): 2Fe2O3 + 3C → 4Fe + 3CO2. Also displaced by carbon monoxide: Fe 2 O 3 + 3CO → 2Fe + 3CO 2. Iron burns in hot air blast to form CO 2 (exothermic): C + O 2 → CO 2. At high temperatures in the furnace,CO 2 is reduced to CO: CO 2 + C → 2CO. Limestone reacts with impurities to form slag, which is tapped off.
Extracting iron from iron ore using a Blast Furnace. Introduction. 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 and also the heat source ...
