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 word for melted iron?
molten
How do you extract iron from iron ore?
The blast furnace is used for extracting iron from its ore. In summary, A mixture called the charge( iron ore-haematite, limestone-calcium carbonate, and coke-pure carbon) containing the iron ore is added through the top of the furnace. Hot air is blasted in through the bottom. After a series of reactions, liquid iron collects at the bottom of the furnace.
Are there ways you can prevent iron reacting with oxygen?
Iron rusts when it reacts with Oxygen. When iron reacts with oxygen, reddish-brown colored iron-oxides are formed. This is called rust Answer:Iron can react with oxygen at many rates some cause red iron oxide (rust) others black iron oxides. Rusting is a slow process which is usually regarded as safe unless the rusting iron is essential for mechanical strength in a system. Iron burns in fireworks to create coloured flames. Steel wool (essentially iron fibers) can burn in air causing injury and igniting other materials. Iron burns when heated in an acetylene flame with excess oxygen resulting in molten iron spray. Iron burns violently in a pure oxygen atmosphere.Aside: When iron "unburns" (rust changes back to iron in a thermite reaction) it can be very dangerous and destructive.
What is the core made up mostly of?
Iron is the main ingredient.

What are examples for liquid?
Molten iron, water, liquid oxygen.
What did Henry Bessemer add to iron to make steel.?
By blowing air through the molten pig iron. By adding oxygen to the iron it removed impurities which escape as gas or form a solid slag
How is a metal made?
Metals are extracted from their ore through chemical reaction. Iron ore is an oxide of iron. The oxygen is removed from the ore by heating carbon with the ore to create molten iron and Carbon Dioxide.
What is the purpose of blowing oxygen into molten iron?
Blowing into molten cast iron causes the oxygen(02) to react with the carbon thus forming carbon dioxide. This is then bubbled away as the temperature is close to 20000 Celsius, this energizes the the gas which causes it to rise.
What is the composition of the inner core?
iron (85 %) with some (4-5%) nickel and the remainder oxygen, silicon, hydrogen and carbon
What metal did Henry Bessemer invent a cheaper way to make?
Steel. He figured out that if air was blown into the molten iron it would remove the particles that were impurities in the iron. This made steel.
Who developed a procedure to produce steel cheaply and easily?
It is called the Bessemer process. Iron has particles in it and air is blown into the molten iron to get rid of the impurities in the iron. It becomes steel.
What did William Kelly and Henry Bessemer invent?
they invented the first inexpensive industrial process for the mass-production of steel from molten pig iron. The process is named after its inventors, who took out a patent on the process in 1855. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.
Where would it be easiest to drill though Earth?
Through the center? Impossible anywhere, since the core of the Earth is molten iron. The shortest PATH would be from pole to pole, but you still have the problem of the molten iron flowing through the core.
What is the inner and outer core of the earth made of?
The inner and the outer core of the earth are made up iron and nikel mostly.
When was the Bessemer steel process discovered?
The Bessemer process was the first inexpensive industrial process for the mass-production of steel from molten pig iron. The process is named after its inventor, Henry Bessemer, who took out a patent on the process in 1855. The process was independently discovered in 1851 by William Kelly. The process had also been used outside of Europe for hundreds of years, but not on an industrial scale. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.
