Electrometallurgy
Electrometallurgy as a word comes from the addition of the Latin based electrum, or Greek ḗlektron (meaning amber, natural resin, which produces static electricity). It refers to the use of electricity to treat, extract (Electrowinning), refine (Electrorefining) or purify (Electrolysis or Electropolishing) metallic substances. It is also used to as a more general term to describe the plating of a layer of metal on another such as gold plating (Electroplating or Electroforming).
