Question

What is the most common type of electrometallurgical processes to obtain pure metal?

• A. Electro-refining
• B. Electrowinning
• C. Both a and b
• D. Oxidation

Answer 1

Answer: (C)

Both a and b

The most common types of electrometallurgical processes are electrowinning and electro-refining. Electrowinning is an electrolysis process used to recover metals in aqueous solution, usually as the result of an ore having undergone one or more hydrometallurgical processes. Electro-refining is used to dissolve an impure metallic anode and produce a high purity cathode.
