Coal, distilled in a retort to expel the volatile content and leave the carbon as a spongy-looking solid called "coke".
(Strange - there are several versions of this question, suggesting to me poor teaching or text-books that focus only on the chemistry and not the overall process, purpose?and materials.)?

Why can't aluminium be extracted from aluminium ore using a blast furnace?
Because it is more reactive then carbon to be extracted in a blast furnace. Remember carbon is the reducing agent and for it to work the metal being extracted has to be lower in the reactivity series, e.g. iron
Why you used carbon refractory at blast furnace?
You don't. Carbon burns! The fuel is carbon (as coke). The refractory lining (fire-bricks) is made from minerals with very high melting-points.
Where does the carbon that is used in blast furnace come from?
Coal, distilled to drive off itscontents and leave the carbon, plus a little bit of non-volatile impurities, principally silica; in a form called Coke. (No relation to the colloquialcontraction of Coca-Cola! :-) )
What is the use of carbon dioxide?
used by plants and trees to be turned into oxygen.
What raw materials are used in a blast furnace?
Iron ore or Haematite (Fe3O2), Carbon in the form of 'Coke', and Limestone (Calcium Carbonate 'CaCO3') are all used in the blast furnace. Iron Ore is melted down with coke, the coke burns heat into the furnace. Oxygen gas is blasted in from the sides. The carbon (C) and oxygen (O2) react to form carbon dioxide gas (CO2). At higher temperatures more carbon (C) is reacted with the carbon dioxide(CO2) to create carbon monoxide (2CO). The carbon monoxide 'steals' the oxygen from the iron oxide (Fe3O2), reducing the iron oxide to iron. Due to the impurities in the iron, it is called 'pig iron'. Limestone (CaCO3) is added to remove the impurities from the iron. The limestone (CaCO3) reacts with mainly silicate in the iron, and becomes calcium silicate (CaSiO3) and carbon dioxide (CO2). Calcium silicate is known as 'slag' and is used for construction.
What is Blast Furnace?
A blast furnace is used to extract iron from its ore.
What is used in the furnace to extract the iron?
blast furnace
What is use of mud carbon in blast furnace?
Mudgun is hydraulically operated machine that is used to close the tap hole of the blast furnace after draining out the metal / slag from the furnace from time to time. It is heavy equipment and the most critical of all the equipments used in blast furnace. The failure of the machine will lead to shut down of the furnace to close the tap hole.

What is the waste gas in the Blast Furnace used for?
It is mostly carbon monoxide and nitrogen gases which has some heating value. So it is typically recovered and mixed with natural gas, &/or coke oven gas and used in boilers for steam or other steel heating furnaces for further processing of steel.
What is the difference between blast furnace coke and cupola coke?
Mainly the type of coke being used. The sulfur, ash and carbon content are different.
What element is the blast furnace used to extract?
Iron (Fe)
How tall is a blast furnace?
The air (hot blast and possibly added oxygen) ranges from 1800 to 2200F (depending on equipment and operating conditions. The flame temperature (RAFT) is between 3400 and 4200F. The liquid pig iron is generally about 2700F.
What is difference between Cupola furnace and blast furnace?
In essence nothing, a Cupola furnace is a type of blast furnace in that it is charged at the top and tapped at the bottom and air is blasted into the furnace via a wind belt and tuyres. A blast furnace in a steel works is a huge structure operated for long periods of time, it is charged with iron ore, coke and limestone and reduces the iron ore into pure iron. A Cupola furnace, as used in the foundry re melts pig iron, from the blast furnace, along with foundry scrap, steel scrap and scrap iron engine blocks and produced iron alloys of various specifications. A Cupola furnace is usually operated on a daily basis but some types can be continuously operated for several weeks
