EXTRACTION OF IRON IN A BLAST FURNACE reduction

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.

(PDF) EXTRACTION OF IRON Fahad Zafar - Academia.edu

A preheated blast of air at 1500 O C, is blown into the furnace under pressure near to the bottom. The blast oxidizes carbon to CO 2. C + O 2 CO 2 + heat Formation of CO 2 is an exothermic reaction in which a huge amount of heat is liberated which rises the temperature to 1900 O C in this region.

THE BLAST FURNACE - IRON PRODUCTION

Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
