Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide converts iron oxides to elemental iron. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide.

 · Still, some general principles are common to all the extraction processes of metals. For obtaining a particular metal, first we look for minerals which are naturally occurring chemical substances in the earth's crust obtainable by mining. Out of many minerals in which a metal may be found, only a few are viable to be used as sources of that metal. Such minerals are known as ores. 2. Elements ...

 · Steelmaking: the basic oxygen process. Impurities in the iron from the Blast Furnace include carbon, sulphur, phosphorus and silicon. These have to be removed. Removal of sulphur. Sulphur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulphide. This forms a slag on top of the iron and can be ...

There are five different types of iron Cast iron, Mild Steel, Wrought Iron, Highcarbon steel, Stainless steel. It is based on their amount of carbon content they have. Carbon is used to extract iron, so some carbon remains with the iron metal. Cast Iron: Cast iron is the metal which is directly obtained from the blast furnace without any processing. It is also known as pig iron. Cast iron is ...
