Iron is the second most abundant metal in the Earth's crust (after aluminium) and more iron is made than all the other metals put together. The ores, which are mainly the oxides, are reduced to iron with carbon (coke) at high temperatures in a blast furnace.
Mar 07, 2010 · The conversion of the Iron ore to the metallic Iron is a chemical reduction, but depends upon the chemical nature of the ore being used, for example: 2 Fe2O3 + 3 C (as coke) ---> 4 Fe + 3 CO2 (g) This is actually a series of reactions that are temperature dependent. 3 Fe2O3 + CO ---> CO2 + 2 Fe3O4 (Begins at 850° F) Fe3O4 + CO ---> CO2 + 3 FeO ...
The quality of the tools made from it was highly variable, depending on the region from which the iron ore was taken and the method used to extract the iron. The chemical nature of the changes taking place during the extraction were not understood; in particular, the importance of carbon to the metal's hardness.

CaO now reacts the impurities of ore called GANGUE to form slag. Slag is the mixture of CaSiO 3 and Ca(AlO 2) 2. The slag floats over the top of molten iron. Slag is a useful byproduct. It is used in road making, cement manufacturing a light weight building materials.
Iron is a moderately reactive metal which joins readily with non-metals such as oxygen. This is why we do not find pure iron in the Earth's crust. Instead it is found as an ore, in which iron is chemically combined with oxygen or other non-metals. Most workable iron ores are rich in iron (III) oxide, Fe 2 O 3. Making iron by removing oxygen ...
Types of iron ore: Hematite ore. Hematite ore is a direct-shipping ore with naturally high iron content. Because of its high iron content, hematite ore must undergo only a simple crushing ...
Rock that is rich in a valuable mineral is referred to as ore. Most iron ore contains some form of iron oxide (e.g. Fe 2 O 3, Fe 3 O 4). 3 In order to extract iron from iron ore, one must first remove the unwanted minerals, then remove the oxygen from the iron. The latter step can only be achieved with a chemical reaction.
There are 83 chemical composition of iron ore suppliers, mainly located in Asia. The top supplying countries or regions are China, Morocco, and Pakistan, which supply 95%, 2%, and 1% of chemical composition of iron ore respectively. Chemical composition of iron ore products are most popular in Domestic Market, Southeast Asia, and Eastern Europe.

Oct 02, 2014 · Pig Iron. Pig iron is the basic material from which, wrought iron and steels are produced. It is obtained by smelting (chemical reduction) of iron ore in the blast furnace. In addition to iron, Pig iron contains varying quantities of other elements such .
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
Aug 10, 2011 · Blast furnaces extract pure iron from the iron (III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C (s) + O2 (g) -> 2CO (g) In the second step, iron (III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe2O3 (s) + 3CO (g) -> 2Fe (s) + 3CO2 (g) Write the net chemical equation for the production of iron from ...
To get to the bits of iron in the ore, you have to smelt it out. Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores.

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being ...
The chemical formula for iron (III) oxide is Fe2O3. This compound is also called hematite, iron ore and specularite. Hematite is a mineral naturally found on earth and appears as a gray or reddish compound. Iron (III) oxide results naturally when iron and .

When the ore is melted, it is poured into molds. It cools and forms a scale on the surface that acts as a protective covering for the metal. However, cast iron is naturally prone to rusting because of its high iron composition. When iron comes into contact with oxygen and water vapor, a chemical reaction occurs, and rust is the visible result.

Iron ore is the source of primary iron for the world's iron and steel industries.
The Iron Age had begun. Some kinds of iron were clearly superior to others depending on its carbon content, although this was not appreciated. Some iron ore contained vanadium producing so-called Damascene steel, ideal for swords.
