Limestone is used in the blast furnace as a flux material to help remove impurities such as silica, which would otherwise form a slag that interferes with the smelting process. When limestone is added, it combines with the impurities to form a molten slag that can be easily separated from the molten iron.

What are the 3 raw materials used in the blast furnace?
The three raw materials used in a blast furnace are iron ore, coke, and limestone. Iron ore is the primary source of iron, coke is used as a fuel and reducing agent, and limestone helps to remove impurities from the iron ore.
Which three substances are put into the blast furnace?
In a blast furnace, iron ore (Fe2O3), coke (carbon), and limestone (CaCO3) are commonly used. Iron ore is the source of iron, coke acts as a fuel and reduces the iron ore to iron, and limestone helps remove impurities by forming a slag.
What substance are mixed with iron ore in the blast furnace?
Coke (a form of carbon) and limestone are mixed with iron ore in the blast furnace. Coke provides the heat source for the chemical reaction, while limestone helps to remove impurities from the iron ore.
What is the charge in the blast furnace?
The charge in the blast furnace typically consists of iron ore, coke (a form of coal), and limestone. The iron ore is the main source of iron, the coke provides the heat and reducing agent, while the limestone helps remove impurities in the form of slag.
What goes into a blast furnace?
A blast furnace typically contains iron ore, coke (fuel derived from coal), and limestone. These materials are layered in the furnace and hot air is blown in at the bottom to create a chemical reaction that produces molten iron.
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 are the 3 raw materials used in the blast furnace?
The three raw materials used in a blast furnace are iron ore, coke, and limestone. Iron ore is the primary source of iron, coke is used as a fuel and reducing agent, and limestone helps to remove impurities from the iron ore.
What is a common flux in a blast furnace?
Limestone, dolomite, BOF slag, electric furnace slag, olivine

What is Blast Furnace?
A blast furnace is used to extract iron from its ore.

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
What three materials are used in a blast furnance?
The three materials typically used in a blast furnace are iron ore (mainly hematite or magnetite), coke (a form of carbon derived from coal), and limestone (as a flux to help separate impurities from the molten iron).
