extraction of iron by blast furnace in gujarati
Describe the extraction of Iron from its Hematite ore in ...
EXTRACTION OF IRON: The most important raw materials or ores from which iron metal extracted are oxide ores hematite (Fe2O3) or limonite (Fe2O3. 3H2O). The first stage involved in the manufacture of iron is the reduction of oxide ores in a blast furnace as given in fig. This involves the crushing of the oxide ore to produce lumps.
Iron Ore Mining Techniques, Metal Extraction, Types of ...
extracting iron from iron ore using blast furnace: Extracting iron from its ore requires a series of steps to be followed and is considered as the penultimate process in metallurgy. The steps need the ore to be concentrated first, followed by the extraction of the metal from the concentrated ore after which the metal is purified.
Alevel Chemistry/AQA/Module 2/Extraction of Metals ...
Extraction of Iron: Iron, Fe, is extracted from its metal oxide in the Blast Furnace using Carbon as a reducing agent. To the Blast Furnace, the following 'ingredients' are added: Hematite (Fe 2 O 3 ), Limestone (CaCO 3 ) and Coke (C).
iron ore processing for the blast furnace
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.
Reactions occurring in blast furnace
Extraction of iron in a blast furnace is a continuous process with reactants being fed in and products removed. The iron produced is referred to as pig iron has a carbon impurity (45%) that makes it too brittle to be useful.
Iron Production Chemistry LibreTexts
The production of iron from its ore involves an oxidationreduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides.

The Blast Furnace | Scool, the revision website
The method. Three substances are needed to enable to extraction of iron from its ore. The combined mixture is called the charge: Iron ore, haematite often contains sand with iron oxide, Fe2O3. Limestone (calcium carbonate). Coke mainly carbon. The charge is placed a giant chimney called a blast furnace.
flow chart of extraction of iron by blast furnace
This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. 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 ...
What is a blast furnace and how does it work? | AnswersDrive
Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
Extracting Iron from Iron Ore in a Blast Furnace Essay ...
The Iron is extracted from the ore that contains the most amount of iron. The iron is extracted from its oxide ore called Hematite. Many things are produced in the extracting or iron from iron ore in a blast furnace. The iron ore is reacted with carbon and oxygen in .
Selective leaching of zinc from blast furnace dust with ...
According to the pH values of the lixiviants and the stability constants shown in Table 3, it can be inferred that the decreases of the pH and the stability constants can improve the dissolution of both the zinc and undesired iron from blast furnace dust. For these theoretical and practical reasons, iminodiacetic acid was chosen as the ligand to extract zinc from blast furnace dust because of its .
Smelting Wikipedia
Smelting. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
Extracting Iron and Steel
Aug 13, 2010· Extracting iron from iron ore using a Blast Furnace . Introduction ... In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something.
Blast furnace
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron, but also others such as lead or a blast furnace, fuel, ore, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes ...
