The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

Titanium metal is mainly produced by reducing titanium tetrachloride (TiCl 4) which is manufactured from natural rutile or from ilmenite, called Kroll's process. Iron is separated from the ilmenite during a smelting operation, and a TiO 2rich slag is produced which is then transformed to TiCl 4 by chlorination.

The smelting process. Smelting is a pyrometallurgical process that extracts metals from ores by heating them to high temperatures under the influence of a reducing agent, such as carbon or coke. Smelting's primary purpose is to remove the metal content from contaminants in the ore, such as oxides and silicates. Preparation.

The cast iron is usually extracted from its oxide ore (haematite). This process involves the following steps: 1) Concentration The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size. The crushed ore is concentrated by gravity separation process in which it is washed with water to remove clay, sand, etc.

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

An ore is a type of rock containing compounds from which metals can be extracted. Ores are typically metal oxides or a compound of a metal that can be converted to an oxide. For example, the main aluminium ore is called bauxite which is aluminium oxide (Al 2 O 3). The metal is removed from the oxide in a process called reduction.
