Haematite is an ore of ...............

Answer

**Step-by-Step Solution:**

1. **Identify the Ore**: The question asks about Haematite, which is a type of ore. An ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted.

2. **Understand the Composition**: Haematite is primarily composed of iron oxide. Its chemical formula is Fe2O3, which indicates that it contains iron (Fe) and oxygen (O).

3. **Determine the Metal**: Since Haematite is an iron oxide, it is primarily associated with the extraction of iron. The presence of iron in the formula Fe2O3 confirms that Haematite is an ore of iron.

4. **Commercial Significance**: Haematite is significant in the commercial production of iron due to its high iron content, which is approximately 70%. This makes it a valuable source for iron extraction in metallurgy.

5. **Conclusion**: Based on the above points, we conclude that Haematite is an ore of iron.

**Final Answer**: Haematite is an ore of iron (Fe).
