Magnetite

Mica

Limestone

Bauxite

- Option 1: Magnetite

- Correct Answer: It is a mineral made of iron oxide with iron in the form of both iron (II) and iron (III).

- Its formula is Fe3O4, and it's mainly used in steel manufacturing.

- Option 2: Mica

- Contains silicate minerals.

- Mainly used in electronics and insulation, not for steel manufacturing.

- Option 3: Limestone

- Composed primarily of calcium carbonate (CaCO3).

- Used mainly in construction and as a material in cement production.

- Option 4: Bauxite

- The main source of aluminum, not iron.

- Primarily used to produce alumina for aluminum manufacturing.
