What did the bessemer converter do?
The Bessemer converter removes impurities from pig iron and produces steel.
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.
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 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?
Oxygen. When oxygen is forced through molted iron it reacts with the carbon, turning into carbon dioxide and bubbles away, leaving a cleaner metal behind.
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.
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.
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.
Which technique removes impurities from the bloodstream because the kidneys are no longer able to?
Dialysis
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".
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.
Why is a filter needed for a fish tank?
The filter removes the fish waste and some of the other impurities.
