Processes and Procedures in the Extraction of Iron. The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron (III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace.

Iron initially extracted in the autoclave is largely reprecipitated, due to the low acidity, as hydrated iron oxides and jarosite. The discharge solution from the firststage leach, typically containing about 8 g/l free acid and 2 g/l iron, is transferred to solution treatment steps.

Iron removal system schema. Iron is often found in water in complexed forms. In order to be eliminated, iron complexed requests a coagulation stage, which comes in between oxidation and filtration. Remark : Thanks to microorganisms, it is possible to remove iron from water by biological way.

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.
