Which of the following metallurgical process for the extraction of indicated metals is CORRECT ?

Options

A. Aluminothermic process :- Al- metal
B. Self reduction process :- Cu - metal
C. Carbon reduction process :- Ag metal
D. Electrolytic reduction method :- Fe metal

Answer

To solve the question regarding the correct metallurgical process for the extraction of indicated metals, we will analyze each option provided.

### Step-by-Step Solution:

1. **Analyze the First Option: Aluminum Thermic Process for Aluminum Metal**
- The aluminum thermic process is primarily used for the extraction of metals like iron, not aluminum itself. In this process, aluminum acts as a reducing agent.
- **Conclusion**: This option is incorrect.

**Hint**: Remember that the aluminum thermic process is typically used to extract iron, not aluminum.

2. **Analyze the Second Option: Self-Reduction Process for Copper Metal**
- The self-reduction process involves the extraction of less electropositive metals like copper, lead, and mercury without the use of an external reducing agent.
- **Conclusion**: This option is correct.

**Hint**: Self-reduction is a method where the metal itself acts as its own reducing agent.

3. **Analyze the Third Option: Carbon Reduction Process for Silver Metal**
- Silver is a less electropositive metal and cannot be effectively reduced using carbon. Carbon is generally used to reduce more electropositive metals.
- **Conclusion**: This option is incorrect.

**Hint**: Consider the position of silver in the electrochemical series; it is less reactive than metals that can be reduced by carbon.

4. **Analyze the Fourth Option: Electrolytic Reduction Method for Iron Metal**
- The electrolytic reduction method is typically used for extracting highly reactive metals such as aluminum, alkali metals, and alkaline earth metals, not iron.
- **Conclusion**: This option is incorrect.

**Hint**: Recall that electrolytic reduction is used for metals that are very reactive and require a different extraction method.

### Final Answer:
The correct metallurgical process for the extraction of the indicated metals is the **self-reduction process for copper metal** (Option 2).
