Iron ore consists mostly of oxygen and iron atoms bonded together into molecules. To convert these oxides of iron to metallic iron, they must be smelted or sent through a direct reduction process to remove the oxygen. Oxygen-iron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond, and the process is done at high temperatures. The iron ore must be powdered and mixed with coke, which is essentially carbon, and the combination must be burnt in the smelting process. The carbon dioxide byproduct goes off into the atmosphere and what is left is almost pure iron.
No ore contains steel. However, IRON ore, such as taconite, produces iron. When alloyed with other metals and carbon, it becomes steel.
Iron ore can be found almost anywhere deep underground. The top countries mining iron ore are China followed by Australia, Brazil, India and Russia. If you google "china iron ore map" in images you'll find the most active iron ore mines in the world.
yes, it is quite easy to remove cu from its ore because cu is less reactive so less energy is required i.e.it can be removed from its ore by just heating its ore in air for two to three times.
Iron ore is a mixture.
The basic process to extract iron from ores is to oxidize the ore into iron oxides (such as FeO, Fe2O3, etc.). The iron oxides are melted and mixed with charcoal or coke (carbon from purified coal). The reaction for Fe(III)oxide is: 2Fe2O3 + 3C ---> 4Fe + 3CO2 Typically the molten product was pored into ingots known as pig iron.
which ore is aluminum extracted from
Miners extract iron ore from the ground.
No; iron ore is mixed with copper and smelted; the ore needs to be refined to extract pure iron. You cannot make a tool out of ore, but rather with pure iron.
A blast furnace is used to extract iron from its ore.
The carbon combines with the oxygen in the ore, separating it from the iron.Excess carbon alloys with the extracted iron, hardening it.
No ore contains steel. However, IRON ore, such as taconite, produces iron. When alloyed with other metals and carbon, it becomes steel.
We extract iron form it's ore so that we can use it for a lot more things. For Example, this process makes wrought iron which can be used for ornamental work in gates. A lot of the iron from the blast furnace can be made into steel. Useful website: gcsescience.com

to extract , as in heating ore to remove iron
An ore is a rock that contains minerals that are useful. For an ore to be considered an ore reserve, it must be economically viable (the value of the extracted mineral must exceed the cost of extraction and processing) and must be technically and legally possible to extract.
Iron is the mineral. Iron is an element and as such, is not composed of any other materials, though iron ore comes out of the ground mixed with many other minerals. The ore must then be processed to extract the pure iron for practicle use.
