Why is limestone added to the blast furnace during the extraction of iron?
Limestone is added to the blast furnace during the extraction of iron to act as a flux. It helps to remove impurities, such as silica, from the iron ore by combining with them to form slag. The slag can then be easily separated from the molten iron.
What is the process called when removing impurities from Iron Ore?
The process is called smelting. It involves heating the iron ore in a furnace with a reducing agent such as coke (carbon) to remove the impurities and extract the pure iron metal.
What is the function of limestone in the furnace?
Limestone is added to the furnace as a flux to help remove impurities from the iron ore during the iron-making process. It reacts with the impurities to form slag, which can be easily removed from the molten iron.
What is iron carbonate?
Iron carbonate is a chemical compound with the formula FeCO3. It is a type of iron ore that is often found in sedimentary rocks. Iron carbonate is not commonly used as a source of iron because it is unstable and tends to decompose into iron oxide and carbon dioxide.
What is the product of iron sulfate plus calcium carbonate?
The product of iron sulfate reacting with calcium carbonate is iron carbonate and calcium sulfate. The iron from the iron sulfate displaces the calcium in the calcium carbonate to form iron carbonate, while the sulfate from the iron sulfate combines with the calcium to form calcium sulfate.
How does calcium carbonate purify iron?
Calcium carbonate (limestone) is used in blast furnaces to capture impurities and form a slag that floats above the molten iron to keep the impurities from mixing back into the iron.
When oxygen is blown into pure iron to remove impurities Wont it react with Iron itself to give iron oxide?
Oxygen is not blown into pure iron, it is blown into molten iron ore (many impurities) and coke has been added to the mix as well. the coke reacts with the impurities and the oxygen to purify the iron ore.

What is the purpose of limestone in the blast furnace?
Limestone is added to the blast furnace as a flux material. It helps to remove impurities in the iron ore by forming a molten slag that floats on top of the molten iron. This slag can then be easily separated from the iron.
How did Bessemer allow better use of iron ore?
This technique involved injecting air into molten iron to remove the carbon and other impurities.
What is the ending of this word equation sodium plus iron carbonate?
assuming you mean sodium plus iron II carbonate, the products are iron plus sodium carbonate. iron is a transitional metal which can make +2 or +3 ions, and YOU need to state that in your word equation. there no such thing as iron carbonate, but there is such thing as iron II carbonate and iron III carbonate
What elements make up iron carbonate?
Iron carbonate is formed from iron, carbon, and oxygen, where carbon and oxygen are in a carbonate ion (-2) form.Iron II carbonate (known as siderite) has the formula FeCO3, where iron has a valence of 2 and the carbonate ion has a valence of -2.Iron III carbonate (ferric carbonate) has the formula Fe2(CO3)2 where iron has a valence of 3.

The product of iron sulfate reacting with calcium carbonate is iron carbonate and calcium sulfate. The iron from the iron sulfate displaces the calcium in the calcium carbonate to form iron carbonate, while the sulfate from the iron sulfate combines with the calcium to form calcium sulfate.
Who invented the process to remove impurities by blasts of cold air blown through heated iron?
Henry Bessemer is credited with inventing the Bessemer process, a method to remove impurities from iron by blowing blasts of cold air through heated iron to oxidize impurities. This process revolutionized the steel-making industry by enabling mass production of high-quality steel at a lower cost.
