What is "electrometallurgy"

n. The deposit of a metal coating on a prepared surface by electrochemical means, as in electroplating and electrotyping.

Electrometallurgy is the field concerned with the processes of metal electrodeposition. There are four categories of these processes:

• Electrowinning, the extraction of metal from ores
• Electrorefining, the purification of metals. Metal powder production by electrodeposition is included in this category, or sometimes electrowinning, or a separate category depending on application.
• Electroplating, the deposition of a layer of one metal on another
• Electroforming, the manufacture of, usually thin, metal parts through electroplating
