The chemical process in the production of steel from haematite ore involves Oxidation followed by reduction. True/False

Explanation

To determine whether the statement "The chemical process in the production of steel from haematite ore involves oxidation followed by reduction" is true or false, we can analyze the steps involved in the production of steel from haematite ore.

### Step-by-Step Solution:

1. **Understanding Haematite**:
- Haematite (Fe2O3) is an iron oxide and is one of the primary ores of iron.

2. **Initial Process - Calcination**:
- The first step in processing haematite involves calcination, where the ore is heated in the presence of oxygen. This process can be considered as an oxidation step since the iron in haematite is in a higher oxidation state.

3. **Oxidation Reaction**:
- During calcination, the iron oxide (Fe2O3) is treated with oxygen, leading to the formation of iron oxide in its oxidized form. This confirms that oxidation occurs at this stage.

4. **Reduction Process**:
- After calcination, the iron oxide is subjected to reduction. Near the top of the furnace, Fe2O3 is heated with carbon monoxide (CO), which reduces the iron oxide to iron (Fe) while producing carbon dioxide (CO2). This is a reduction process.

5. **Further Reduction**:
- The remaining Fe2O3 can react further with carbon monoxide to form Fe3O4, which can also be reduced to iron through additional reactions involving carbon monoxide and carbon.

6. **Final Reduction**:
- In the middle of the furnace, carbon dioxide reacts with carbon to regenerate carbon monoxide, which then continues to reduce FeO to iron. This confirms that reduction is a significant part of the process.

7. **Conclusion**:
- The entire process of producing steel from haematite involves an initial oxidation step followed by multiple reduction steps. Therefore, the statement is true.

### Final Answer:
**True**
