Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steelmaking process. Wrought iron. If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.

Iron, atomic number 26, is the most abundant element on earth by mass. It belongs to the 3d series or first transition series of the periodic table. Pure metallic iron is not usually found in the earth's crust. Therefore, extracting metal from ore is the only way to obtain usable iron. Extraction of iron from its ore is a lengthy process and ...

How Iron Was Made. Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s waterpowered hammers ...

The process of extracting metals from their ores is called metallurgy. The process employed in the extraction of the ore depends on the nature of the ore and the impurities present in it. The following are the basic steps for a metallurgical operation: Crushing and grinding of the ore. Concentration of the ore. Working of the ore.

Iron metal is usually extracted from a hematite ore, which contains an iron (III) oxide ( ) compound. The ore must be treated before it can be placed in a blast furnace, because blast furnaces are usually optimized to burn small pieces of ore that are compacted together. Hematite is treated through mineral processing or oredressing processes.

As the blast passes through the burning fuel it takes from the oxide of iron its oxygen, passing out as carbonic oxide, and thus compels it to yield up the whole of the metal iron. The iron, as it melts in the furnace, combines with the carbon of the fuel, and becomes cast iron. Although the process involved in refining purifies the iron to a ...

Metallurgy is the process of extracting pure metal from its ore. Naturally, most of the metals are found in their combined state. So it becomes essential to extract the pure form of metal for various other domestic and commercial purposes. Minerals from which metals can be easily extracted are called Ores.

The coke "steals" the oxygen from the iron oxide (in a chemical process called reduction), leaving behind a relatively pure liquid iron, while the limestone helps to remove the other parts of the rocky ore (including clay, sand, and small stones), which form a waste slurry known as slag. The iron made in a blast furnace is an alloy containing ...

In pyrometallurgy, an ore is heated with a reductant to obtain the metal. Theoretically, it should be possible to obtain virtually any metal from its ore by using coke, an inexpensive form of crude carbon, as the reductant. An example of such a reaction is as follows: () C a O ( s) + C ( s) → Δ C a ( l) + C O ( g) Unfortunately, many ...

Reduction of Iron; The ease with which a metal may be obtained from its ore varies considerably from one metal to another. Since the majority of ores are oxides or can be converted to oxides by roasting, the freeenergy change accompanying the decomposition of the oxide forms a convenient measure of how readily a metal may be obtained from its ore.
