Iron ore is the raw material used to produce pig iron, which is a crucial ingredient in steel production. Approximately 98% of extracted iron ore is utilized in steel manufacturing. Uncontaminated iron ore is nearly absent on the surface of the Earth except for the presence of Fe-Ni alloys from meteorites and exceptionally rare forms of deep ...
- The majority of iron ore is used in the production of steel, one of the most versatile and widely used materials in the world. Blast furnaces and direct reduction processes convert iron ore into molten iron, which is then processed to create various grades of steel for construction, automotive, infrastructure, and heavy machinery applications. 2.

It involves creating underground tunnels and shafts to access the ore. Specialized mining equipment, such as drills, loaders, and haulage vehicles, is used ...
The production of iron and steel requires the provision of a substance that provides both thermal energy and reducing power to convert iron ore into primary iron (called pig iron when solid or hot metal when in liquid form).
Blast furnace uses iron ore as the iron-bearing raw materials, and coke and pulverized coal as reducing agents and heat source, lime, or limestone as the fluxing agents. The main objective of blast furnace ironmaking is to produce hot metal with consistent quality for BOF steelmaking process.
The equipment used to transform iron into steel by removing the impurities is called a converter. The first converter was developed by Bessemer and since then many other processes have also been developed. 1. The Bessemer Process: An Englishman, Henry Bessemer, first invented the Bessemer converter in 1856. The converter is a steel container, shaped like a concrete mixer, …
