When copper ore is mixed with silica in a reverberatory furnace, copper matte is produced. The copper matter contains__________

Options

A. sulphides of copper (II) and iron (II)
B. sulphides of copper (II) and iron (III)
C. sulphides of copper (I) and iron (II)
D. sulphide of copper (I) and iron (III)

Answer

To solve the question regarding the composition of copper matte produced when copper ore is mixed with silica in a reverberatory furnace, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Process**:
- When copper ore (which often contains copper sulfide, Cu₂S) is heated with silica (SiO₂) in a reverberatory furnace, a chemical reaction occurs that leads to the formation of copper matte.

2. **Formation of Copper Matte**:
- The primary components of copper matte are copper sulfide and iron sulfide. The reaction can be summarized as:
\[ \text{Cu}_2\text{S} + \text{FeS} \rightarrow \text{Copper Matte} \]
- Here, copper matte consists of copper(I) sulfide (Cu₂S) and iron(II) sulfide (FeS).

3. **Identifying the Components**:
- Copper matte is primarily composed of:
- Copper(I) sulfide (Cu₂S)
- Iron(II) sulfide (FeS)

4. **Conclusion**:
- Therefore, the correct answer to the question is that copper matte contains copper(I) sulfide and iron(II) sulfide.

### Final Answer:
Copper matte contains **copper(I) sulfide (Cu₂S) and iron(II) sulfide (FeS)**.
