Question

Answer

Answer

Yes B is the correct answer because....All industrial work comes under secondary sector....All manufacturing works are under secondary activity.
So... Converting iron ore to steel is done by industrial unitS.

Answer

Converting iron ore to steel is a part of secondary activity

Introduction:
Converting iron ore to steel is a complex process that involves several stages. This process is classified as a secondary activity, which refers to the transformation of raw materials into finished goods. Secondary activities are an essential part of the manufacturing sector and contribute to the overall economic development of a country.

Explanation:
The process of converting iron ore to steel involves several steps, including mining, crushing, washing, and refining the ore to obtain pure iron. Once the iron ore is extracted and processed, it is then transformed into steel through a process known as smelting. This process involves melting the iron ore in a blast furnace and removing impurities, resulting in the production of molten steel.

Key Points:
1. Iron ore mining: Iron ore is extracted from the earth through mining operations. This primary activity involves the removal of iron-rich rocks and minerals from the ground.
2. Crushing and washing: The extracted iron ore is crushed into smaller particles and washed to remove impurities.
3. Refining: The crushed and washed iron ore is then refined to obtain pure iron. This process involves various techniques such as magnetic separation, gravity separation, and flotation.
4. Smelting: The refined iron ore is then melted in a blast furnace at high temperatures. During this process, impurities are removed, and the iron ore is transformed into molten steel.
5. Steel production: Once the molten steel is obtained, it is further processed and shaped into various forms, such as sheets, bars, rods, or wires, according to the desired end-use.

Conclusion:
Converting iron ore to steel is a secondary activity that involves the transformation of raw materials into finished goods. This process plays a crucial role in the manufacturing sector and contributes to the overall economic growth of a country. By understanding the different stages involved in this process, we can appreciate the complexity and importance of steel production.
