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

  1. Electro-refining
  2. Electrowinning
  3. Both a and b
  4. Oxidation
Correct Answer: Option(c)
Solution: 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.
