Apr 01 2021 The blast furnace is a huge steel stack lined with refractory brick where iron ore coke and limestone are dumped into the top and preheated air is blown into the bottom. The hot air that was blown into the bottom of the furnace ascends to the top in 6 to 8 seconds after going through numerous chemical reactions.
Feb 15 2021 The blast furnace Iron ores such as haematite contain iron III oxide Fe 2O 3. The oxygen must be removed from the iron III oxide in order to leave the iron behind. In this reaction the iron III oxide is reduced to iron and the carbon is oxidised to carbon dioxide.
Mar 03 2020 A blast furnace produces hot metal containing 3.6 C 1.2 Si and 95.2 Fe. The iron ore contains 90 haematite and 10 silica. The coke rate is 480 kgthm and the coke contains 95 carbon and 5 SiO 2. Calculate the weight of iron ore required per thm. Find out
Blast furnaces extract pure iron from the ironIII oxide in iron ore in a two step sequence. In the first step carbon and oxygen react to form carbon monoxide 2C s O2 g 2CO g In the second step ironIII oxide and carbon monoxide react to form iron and carbon dioxide Fe2O3 s
5 CS 2018 06204118 ve 3 This question is about iron. a Three of the raw materials added to a blast furnace used to extract iron from hematite are coke hematite and limestone. Name one other raw material added to the blast furnace. 1 b A series of reactions occurs in a blast furnace during the extraction of iron from hematite. Describe these reactions. .
The Extraction of Iron Chemistry LibreTexts. Extracting iron from iron ore using a Blast Furnace 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
2a. Extraction of Iron in a blast furnace. Sadly now shut down Raw Materials. Iron Ore e.g. haematite ore ironIII oxide the source of iron.. Fe 2 O 3 or magnetite ore. Fe 3 O 4 coke carbon C both fuel and reducing agent. hot air for the oxygen in it to burn the coke. O 2 limestone calcium carbonate to remove certain impurities like silica.
2 The impure zinc oxide can be treated in two ways to extract the zinc a It is roasted in a smelting furnace with carbon coke reducing agent and limestone to remove the acidic impurities. The chemistry is similar to iron from a blast furnace.
The following diagram shows the steps to convert iron from the blast furnace to steel. Scroll down the page for more examples and explanations. The following diagram shows how to extract aluminium from bauxite using electrolysis. Scroll down the page for more examples and explanations.

This is the basic chemical reaction in the blast furnace it has the equation Fe 2 O 3 3CO 3CO 2 2Fe. The limestone in the furnace charge is used as an additional source of carbon monoxide and as a flux to combine with the infusible silica present in the ore to form fusible calcium silicate. Without the limestone iron silicate .
Extraction of Metals. Extraction of Iron.. Chemistry of the blast furnace .. Limestone is calcium carbonate CaCO 3 and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition see examples of other carbonates. .
