What is electrometallurgy?

It is a method that uses electrical energy to produce metals by electrolysis. The electro metallurgical processes can be categorized into four main groups:

  • Electrowinning: It is the extraction of metals by electrodeposition from aqueous solution or melts of their salts.
  • Electrorefining:  It is the purification of metals by electrolysis
  • Electroplating: It is the treatment that modifies the surface of a metal or occasionally a non-metal, without changing
    its bulk properties
  • Electroforming: It is the  manufacture of articles by electrodeposition
