In the extraction of copper, metal is formed in the Bessemer converter due to reaction

Options

A. `2Cu_(2)O to 4Cu+O_(2)`
B. `2CuO+CuS to 3Cu+SO_(2)`
C. `Cu_(2)S+2Cu_(2)O to 6Cu+SO_(2)`
D. `Fe+Cu_(2)O to FeO+2Cu`

Answer

To solve the question regarding the extraction of copper in the Bessemer converter, we need to analyze the reactions that occur during this process. The goal is to identify which reaction leads to the formation of copper metal.

### Step-by-Step Solution:

1. **Understanding the Bessemer Converter**:
- The Bessemer converter is used in the extraction of metals, particularly copper, where oxidation and reduction reactions occur to purify the metal.

2. **Identifying the Possible Reactions**:
- We have four options provided for the reactions that could occur in the Bessemer converter:
1. Copper oxide gives copper plus oxygen.
2. Copper oxide plus copper sulfide gives copper plus sulfur dioxide.
3. Copper sulfide plus copper oxide gives copper plus sulfur dioxide.
4. Copper oxide gives iron oxide plus copper.

3. **Analyzing the Reactions**:
- **Option 1**: Copper oxide decomposing to give copper and oxygen is not a typical reaction in the Bessemer process.
- **Option 2**: This reaction involves both copper oxide and copper sulfide, but it does not represent the main reduction process.
- **Option 3**: Copper sulfide reacts with copper oxide to produce copper and sulfur dioxide. This is a self-reduction reaction where copper sulfide helps reduce copper oxide to copper.
- **Option 4**: This reaction does not represent the extraction of copper, as it involves iron oxide.

4. **Identifying the Correct Reaction**:
- The correct reaction that occurs in the Bessemer converter during the extraction of copper is:
\[ \text{Copper sulfide (Cu}_2\text{S) + Copper oxide (Cu}_2\text{O) } \rightarrow \text{Copper (Cu) + Sulfur dioxide (SO}_2\text{)} \]

5. **Balancing the Reaction**:
- The balanced equation would be:
\[ 2 \text{Cu}_2\text{S} + 3 \text{Cu}_2\text{O} \rightarrow 6 \text{Cu} + 2 \text{SO}_2 \]
- This shows that copper is produced along with sulfur dioxide.

6. **Conclusion**:
- Therefore, the correct option is **Option 3**: Copper sulfide plus copper oxide gives copper plus sulfur dioxide.

### Final Answer:
The metal formed in the Bessemer converter during the extraction of copper is due to the reaction:
**Copper sulfide + Copper oxide → Copper + Sulfur dioxide.**
