Mild steel is iron containing up to about 0.25% 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.

Wrought iron is the perfect form of iron available for commercial purposes. It is made by heating cast iron in a furnace lined with Hematite ( Fe2O3 ), which reacts with carbon in cast iron to produce pure iron and carbon monoxide gas, both of which escape. It is another method of extraction of iron. Fe2O3 + C → 2Fe + 3CO.

The basic extraction of metals from ores has the following steps. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation.
