Electropositive metals like those of group 1 and group 2 are extracted through this process. Extraction of metals is a complicated process and sometimes involves two or more processes to extract the pure element from its ore. The extraction of iron from its ore is an important topic for both class 12th board and JEE. it is explained as follows:

A new route for making steel from iron ore based on the use of hydrogen to reduce iron oxides is presented, detailed and analyzed. The main advantage of this steelmaking route is the dramatic reduction (90% off) in CO2 emissions compared to those of the current standard blastfurnace route. The first process of the route is the production of hydrogen by water electrolysis using CO2lean ...

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.

Mild steel. Mild steel is iron containing up to about % of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things nails, wire, car bodies, ship building, girders and bridges amongst others.
