Iron ( 26 Fe: (18 Ar), 4S 2, 3d 6 ) is found in the earth’s crust in the form of natural ores which contains different iron oxides mixed with impurities such as Silica (SiO 2), (Al 2 O 3), CaO, and MgO, and some harmful impurities such as s, p and As, The suitability of the ore in the extraction of iron economically depends on three factors which are:

The most common of the modern methods used to extract iron from its ores is coke smelting in a blast furnace. The development of this technique is largely credited to Abraham Darby, who set up his Brass and Iron Works in Shopshire in 1709, which was important in the creation of the industrial era that followed.

This activity models a modern method for the extraction of gold and other precious metals such as silver from rocks. The steps of the Washoe Process modeled here include the grinding and preparation of ore for extraction with mercury, and the reduction of the precious metal so it can be processed into the pure metal.

The main ores are: i) Haematite (Fe2O3) ii) Magnetite (Fe3O4) iii) Iron Pyrites (FeS2) o The main iron ore is Haematite (iron (III) oxide
The process of the extraction of iron is carried out by the following steps: Concentration of ore Calcination or Roasting of ore Reduction of ore : Concentration of ore: In this metallurgical operation, the ore is concentrated by removing impurities like soil etc. The process involves the crushing and washing of ore.
