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〔Popov ''et al.'', p.1〕 *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.〔Popov ''et al.'', pp.2,30〕 *Electroplating, the deposition of a layer of one metal on another〔 *Electroforming, the manufacture of, usually thin, metal parts through electroplating〔 ==See also== *Electropolishing, the removal of material from a metallic workpiece 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「electrometallurgy」の詳細全文を読む スポンサード リンク
