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

What is cupola furnace?

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
