What did the bessemer converter do?
The Bessemer converter removes impurities from pig iron and produces steel.
How does limestone purify iron?
It removes the sandy impurities in the iron formed as 'slag' [calcium silicate] CaCO3---> CaO + CO2 CaO + SiO2 ----> CaSiO3.
What is the Bessemer Machine?
It isn't so much a machine. It is a method. It is used to make iron into steel. Iron has impurities and Bessemer found out that if you pump air into the iron it removes the impurities and it becomes steel.
What system removes excess sugar and impurities from the blood?
The excretory system removes excess sugar and impurities from the blood.
What gas removes impurities in pig iron?
The gas that is commonly used to remove impurities in pig iron is carbon monoxide. It reacts with the impurities in the iron, such as oxygen and sulfur, to form less reactive compounds that can be easily separated.
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.
Is steel a type of iron?
Steel is actually iron that was smelted at much higher temperatures than normally (usually with a blast furnace). This extreme heat that is added removes many more impurities, actually making it denser and harder than usual iron.
What are the main impurity in iron ore?
The main impurities in iron ore are silica, alumina, phosphorus, and sulfur. These impurities can affect the quality of the iron produced during the smelting process and need to be minimized through beneficiation processes.
Explain how limestone purifies the iron?
When limestone reacts with iron, it removes impurities and forms slag, which is less dense than molten iron and therefore floats over it, allowing it to be tapped off seperatly. It (the slag) is rather useless, but can be used in concrete.
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 heating iron ore to a high temp in a blast furnace?
Heating iron ore to a high temperature in a blast furnace allows the iron to be extracted from the ore through a chemical process called reduction. This process removes impurities and creates molten iron, which can then be used to make various iron and steel products.
Is the phrase clean all impurities correct?
Not really. One doesn't clean an impurity, one removes it from something. So either "remove all impurities" or "clean (something) of impurities".
