Options

A. `Cu_(2)S + 2Cu_(2)O rarr 6Cu + SO_(2)`
B. `Cu_(2)O + FeS to Cu_(2)S + FeO`
C. `FeO + SiO_(2) to FeSiO_(3)`
D. None of the above

Explanation

### Step-by-Step Solution:

1. **Understanding Bessemerisation**:
- Bessemerisation is a process used for the extraction of copper from its sulfide ores. It involves the conversion of copper sulfide (Cu₂S) into copper metal (Cu) using a Bessemer converter.

2. **Initial Reaction**:
- The first step involves heating the copper sulfide ore in the presence of air. This process converts a portion of the copper sulfide into copper oxide (CuO) and sulfur dioxide (SO₂).
- The reaction can be represented as:
\[ 2 \text{Cu}_2\text{S} + 3 \text{O}_2 \rightarrow 2 \text{Cu}_2\text{O} + 2 \text{SO}_2 \]

3. **Self-Reduction**:
- In the Bessemer converter, the copper oxide formed reacts with the remaining copper sulfide. This is known as self-reduction, where the copper oxide reduces the copper sulfide to produce copper metal.
- The reaction can be represented as:
\[ \text{Cu}_2\text{O} + \text{Cu}_2\text{S} \rightarrow 4 \text{Cu} + \text{SO}_2 \]

4. **Final Reaction**:
- The overall reaction during Bessemerisation can be summarized as:
\[ 2 \text{Cu}_2\text{S} + 3 \text{O}_2 \rightarrow 4 \text{Cu} + 2 \text{SO}_2 \]
- This indicates that copper sulfide is reduced to copper, while sulfur is oxidized to sulfur dioxide.

5. **Conclusion**:
- Therefore, the main reaction taking place in the Bessemer converter during the Bessemerisation of copper is the self-reduction of copper sulfide to copper using copper oxide.

### Answer:
The reaction taking place in the Bessemer converter during Bessemerisation of copper is:
\[ \text{Cu}_2\text{O} + \text{Cu}_2\text{S} \rightarrow 4 \text{Cu} + \text{SO}_2 \]
