1. Mining: Iron ore is extracted from the ground through mining operations.
2. Processing: The extracted iron ore is processed to remove impurities and create iron concentrate.
3. Smelting: The iron concentrate is then smelted in a blast furnace to produce pig iron, which is a raw form of iron.
4. Refining: The pig iron is further refined through processes such as basic oxygen steelmaking or electric arc furnace to produce steel.
5. Fabrication: The steel is then fabricated into various products such as beams, sheets, pipes, and wires through processes like rolling, forging, and casting.
6. Finishing: The final stage of value addition involves finishing processes such as painting, coating, or galvanizing to enhance the appearance and durability of the iron products.

1. Mining: Iron ore is extracted from the earth through mining operations.
2. Crushing and screening: The mined ore is crushed into smaller pieces and screened to remove impurities.
3. Beneficiation: The crushed ore is processed to remove impurities and concentrate the iron content. This can be done through various methods, such as magnetic separation, flotation, and gravity separation.
4. Sintering: The concentrated ore is heated in a sintering furnace to form porous lumps called sinter. Sintering improves the ore's strength, making it more suitable for use in blast furnaces.
5. Blast furnace: The sinter is fed into a blast furnace along with coke (a fuel) and limestone (a flux). The coke burns, producing heat that melts the ore and reduces the iron oxides to iron. The molten iron, known as pig iron, collects at the bottom of the furnace.
6. Steelmaking: The pig iron is refined in a steelmaking furnace to remove impurities and adjust the carbon content. This process can use various steelmaking methods, such as the basic oxygen process (BOP), electric arc furnace (EAF), or open hearth furnace.
7. Rolling: The molten steel is poured into molds and rolled into various shapes, such as sheets, plates, bars, and wire rods.
8. Finishing processes: The rolled steel products may undergo additional finishing processes, such as annealing, tempering, and coating, to improve their properties and meet specific end-use requirements.
