The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Metallurgy**: Metallurgy is defined as the branch of science and engineering that deals with the extraction of metals from their ores and the preparation of metals for use. 2. **Extraction Process**: The process of metallurgy involves three main steps: - **Concentration of Ore**: This is the first step where the ore is purified to increase the concentration of the desired metal. This may involve physical or chemical methods to remove impurities. - **Extraction of Metal**: The second step involves extracting the metal from the concentrated ore. This can be done through various methods such as pyrometallurgy (using heat), hydrometallurgy (using aqueous solutions), or electrometallurgy (using electrical energy). - **Refining of Metal**: The final step is refining, where the extracted metal is purified to remove any remaining impurities and to improve its quality. 3. **Conclusion**: Therefore, metallurgy is fundamentally the process of extracting metals from their ores, which encompasses the concentration, extraction, and refining of metals. 4. **Final Answer**: The correct answer to the question "Metallurgy is the process of:" is "extracting the metal from its ore." ---
