THE BLAST FURNACE - IRON PRODUCTION

A simplified diagram of a Blast Furnace is drawn below. A typical blast furnace may be up to 32 metres in height and 10 metres in diameter. They have thick steel sides, lined with refractory bricks, to ensure that heat is not lost. 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 ...

Useful Products from Rocks - Chemistry GCSE Revision

Extraction of Iron Ore from a Blast Furnace. A metal such as iron, which is less reactive than carbon, can be extracted from its ore using carbon. Reactions in the blast furnace: C + O 2 > CO 2; The coke burns, to form carbon dioxide and to produce heat; CO 2 + C > 2CO; The carbon dioxide reacts with more hot coke to produce carbon monoxide gas.

Blast furnace GCSE Wiki Fandom

Blast furnaces are used for extracting fairly reactive metals (e.g. iron, zinc) by reducing the metal oxide with carbon. Iron is extracted from haematite and magnetite (different oxides of iron). This happens in a blast furnace. A blast furnace is roughly 50m high, and lined with heat–resistant bricks. The haematite (the ‘charge’) is loaded into the blast furnace, along with coke (heated ...

PROCESSES INSIDE THE BLAST FURNACE

Iron ore, limestone and coke is the ‘’stock’ of the blast furnace. This is fed into the furnace at its top. A variety of processes take place within the blast furnace, as the ‘stock’ slowly moves downwards and temperatures increase. The removal of oxygen through the chemical process called ‘reduction’ is crucial (oxygen combines with carbon monoxide, forming carbon dioxide gas ...
