उत्तर
Manganese is added to iron ore to make it a stronger metal.
Explanation:
Manganese is an essential raw material required to transform raw iron ore into high-quality steel. When used in the production process, it serves as a strong deoxidising and desulfurizing agent, eliminating impurities from the molten metal. This chemical bonding significantly increases the iron's tensile strength, toughness, and endurance, making the finished metal very resistant to hard impact, wear, and structural deformation
