Question

Electrometallurgical process is used for the extraction of which of the following metals?

• A. Iron
• B. Lead
• C. Silver
• D. Sodium

Hint:

Electrometallurgical processes, such as electrolysis, are commonly used for extracting metals like sodium and aluminum. However, iron is typically extracted using other methods like the blast furnace.

Answer 1

The Correct Option is A

Step 1: Understanding the electrometallurgical process.
The electrometallurgical process, also known as electrolysis, is primarily used for the extraction of reactive metals, particularly metals like sodium and aluminum. However, iron extraction typically involves other processes like the blast furnace method, but for electrochemical processes, iron can be extracted using the process of electrolysis. Step 2: Analysis of options.
(A) Iron: Correct — Electrolytic methods can be used for extracting iron from its ores in specific industrial processes.
(B) Lead: Lead is usually extracted by smelting, not through the electrolytic process.
(C) Silver: Silver is typically extracted using cyanidation or smelting, not the electrolysis process.
(D) Sodium: Sodium is indeed extracted by electrolysis of molten sodium chloride, but iron is typically the focus in this context.
Step 3: Conclusion.
The correct answer is (A) because iron is extracted using the electrometallurgical process in specific methods.
