Metallurgy is the process of

Options

A. extracting metals from the Ore
B. roasting the Ore
C. liquefaction of nitrongen
D. adding carbon to the Ore in blast furnace

Answer

**Step-by-Step Solution:**

1. **Definition of Metallurgy**: Metallurgy is the branch of science and engineering that deals with the extraction of metals from their ores, as well as the purification and refining of these metals.

2. **Key Processes in Metallurgy**:
- **Extraction**: This is the first step where metals are extracted from their ores. This involves mining the ore from the earth.
- **Purification**: After extraction, the metal needs to be purified to remove impurities and enhance its quality.
- **Refining**: This step involves further processing to improve the mechanical properties and purity of the metal.

3. **Steps Involved in Metallurgy**:
- **Mining the Ore**: The first step is to mine the ore, which is the naturally occurring material from which a metal can be extracted.
- **Separating and Concentrating the Metal**: The second step involves separating the metal from the ore and concentrating it to increase the metal content.
- **Reducing the Ore to Metal**: The final step is to reduce the concentrated ore to obtain the pure metal.

4. **Additional Processes**: In some cases, additional processes may be required to improve the mechanical properties of the metal or to increase its purity.

5. **Conclusion**: Therefore, metallurgy is fundamentally the process of extracting metals from ores, purifying them, and refining them for various applications.
