Which three substances are put into the blast furnace?
Limestone, Iron Ore and Coke.
What are the three substances fed into the blast furnace?
Carbon rich coke limestone and iron
Why is Limestone added to a Blast Furnace for producing Iron?
it purifies it
What goes into a blast furnace?
Sinter, which is a mixture of iron ore, coke and limestone, and a blast of hot air. Externally to the furnace, iron ore, coke and limestone are mixed together Intimate mixing ensures that the reactants are as close as possible to each other. This is loaded into the top of the blast furnace. A blast of hot air ( ~ 1100 oC) is sent in at the bottom of the furnace, through tuyeres. The oxygen (air) is also one of the reactants. The products are tapped from the bottom of the furb=nace are liquid iron and 'slag' ( calcium silicate).
What is the process of smelting iron ore?
Iron ore is not normally smelted, instead it is reduced in a blast furnace with a mixture of coke & limestone. The coke burns removing the oxygen from the iron ore and melting the resulting iron. The limestone neutralizes acidic sulfur compounds and acts as a flux.
What is coke for in a blast furnace?
the Coke supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron.
How does limestone coke and iron ore get into the blast furnace?
through the top of the blast furnace
Pig iron is produced by heating the coke iron and limestone in a what?
Pig iron is produced when heating * Iron ORE (not iron as the question says!) * Coke * limestone in a Blast Furnace.

Is iron oxide ruduced or oxidised in a blast furnace?
It is 96% iron (the rest is mostly sulphur etc.).
What raw material are put into a blast furnace?
The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.

What is the function of coke in a blast furnace?
Coke is used in furnaces as a reducing agent.
How is iron refined?
Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie
