Why is Limestone added to a Blast Furnace for producing Iron?
it purifies it
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 the blast furnace during the extraction of iron?
Iron ore contains the impurities sand and clay, which are silicon oxides. Limestone is added to remove these impurities.
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).
How does limestone coke and iron ore get into the blast furnace?
through the top of the blast furnace
How is limestone usefull?
because in a blast furnace the limestone removes unwanted substances as slag.
What is a common flux in a blast furnace?
Limestone, dolomite, BOF slag, electric furnace slag, olivine

Limestone, Iron Ore and Coke.
What is the purpose of limestone in the blast furnace?
The limestone decomposes to quicklime and carbon dioxide, and the quicklime removes acidic impurities (eg SiO2). So basically limestone is to remove impurities
How does the function of the tonsils compare to the function of a furnace?
It doesnt
What are the three substances fed into the blast furnace?
Carbon rich coke limestone and iron
What is function of furnace?
A furnace is a device used for heating.It convert sample to ash.
What is Function of refractory lining in the furnace?
tell me funtion of tube types of furnace
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
