Haematite is an ore of which metal ?

Options

A. Bauxite
B. Aluminium
C. Iron
D. Gold

Explanation

**Step-by-Step Solution:**

1. **Understanding Ores**: Ores are naturally occurring minerals from which metals can be extracted profitably. Each ore is associated with a specific metal.

2. **Identifying Hematite**: The question asks about hematite, which is a specific mineral. We need to determine which metal is extracted from hematite.

3. **Comparing with Other Ores**: The transcript mentions bauxite, which is an ore of aluminum (Al2O3.2H2O). This helps us understand that different ores correspond to different metals.

4. **Finding the Correct Metal**: The transcript states that hematite is an ore of iron. The chemical formula for hematite is Fe2O3, indicating that it contains iron.

5. **Extraction Process**: Hematite is processed in a blast furnace where it undergoes reduction to extract iron. Carbon monoxide is used in this process, and carbon dioxide is released as a byproduct.

6. **Conclusion**: Based on the information provided, hematite is confirmed to be an ore of iron.

**Final Answer**: Hematite is an ore of iron.
