Blast furnace operation-Blast furnace Produces pig iron from iron ore and sinter. The iron oxide of ore and sinter is reduced to iron with the help of carbon monoxide(Co) which is produced inside the furnace by the action of hot air at about 1000. oC with coke.

Iron works are located close to coal fields so that plentiful of coal is available at cheap rate. Coal is used as reducing agent and as fuel. Pig iron is converted into cast iron by heating molten pig iron with scrap iron and coke in specially designed furnaces. A blast of hot air is blown through the mixture. Cast iron contains about 3% carbon.

The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state. A Blast furnace is a gigantic, steel stack lined with ...

Students reduce iron(III) oxide with carbon on a match head to produce iron in this small scale example of metal extraction. The experiment can be used to highlight aspects of the reactivity series. This experiment can easily be carried out on an individual basis by students. The experiment itself ...

In a blast furnace, iron ore reacts with hot coke to produce pig iron. The sintering or pelletising process prior to the blast furnace operation is added to allow blending of iron ores and also to control the size of the blast furnace feed. Sintering or pelletising improves the blast furnace operation and reduces energy consumption.

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.

Sep 13, 2013· Extraction of Iron (Fe) from its haematite Iron is extracted by heating the iron ore with carbon in the blast furnace. Three substances are needed to enable the extraction of iron from its ore. The combined mixture is called the charge:-Haematite, iron …
