Best Answer

Iron ore is mixed with coke (almost pure carbon from coal) and roasted at high temperatures. The carbon reacts with the oxygen to produce carbon dioxide leaving the elemental iron.

How oxygen remove from steel?

Oxygen is removed from iron ore to produce iron which is then refined and alloyed with other metals and constituents to form steel. The oxygen is removed from the iron ore by heating it to a high temperature in the presence of carbon (and other materials) as a reducing agent. Indeed, once iron is produced in this way some processes actually blow oxygen through the iron to burn away impurities. My point here is that most steel production does not involve removal of oxygen once iron has been smelted.


Is it true or false iron is separated from oxygen by cooling iron ore?

False. The ore is heated (smelting)


How is iron extracted from rocks?

Iron ores consists mostly of oxygen and iron atoms bonded together into molecules. To convert these oxides or 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 whole must be burnt in the smelting process.It is reduced with carbon by smelting. It is placed in a furnace with carbon coke and lime is added to reduce impurities


How oxygen is removed from an ore to obtain the pure metal?

Heat


What type of resource is iron ore?

Iron is a natural resource. It is found in nature as Iron Ore, which is iron with oxygen and other impurities. These impurities are removed by heat treating the Iron Ore and melting away the impurities, due to different melting points of the impurities.

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.


How is the iron excacted in old ages?

Iron ore was mixed with limestone and charcoal. The charcoal would be ignited, and air forced through the mix. The charcoal would removed the oxygen from the iron ore, leaving iron.


How is iron removed from the earth's crust?

Iron ore is removed with dynamite and lots of heavy equipment. It starts as iron ore and is mixed with coke (carbon). This is a displacement reaction which means that the iron is separated from the ore and you have iron on its own.

Haematite is an ore of?

Hematite is a mineral made of iron and oxygen. It can be gray, red, or brown.


A molecule becomes reduced when it?

Simply put, the process of oxidation is that of reacting to add oxygen. Carbon (C) burning in air (O2) to form Carbon Dioxide (CO2) is and Oxidation reaction. Conversely, the process of removing oxygen form a molecule is a reduction. When a lump of iron ore is heated with carbon, oxygen is removed and metallic Iron is produced and the Iron ore is said to have been reduced.


What happens to the element in iron ore when the ore is mixed with carbon and heated?

Iron ores most often contain iron combined with oxygen. The carbon comes from a material called coke, which is made from coal. When heated, the carbon reacts with oxygen in the ore, leaving the purified iron metal behind.


Is iron ore a rock?
