What is Electrowinning

The electrolysis process used in electrowinning allows the elemental metal to be recovered This sets electrowinning apart from other recovery technologies such as evaporation and ion exchange which result in little more than a more concentrated metal-bearing solution Despite this the metal recovered is usually still not pure enough to be used in plating if left unprocessed...

WO2015056121A1

The invention relates to a process of electrowinning or electrorefining of metals in particular noble metals such as copper that is carried out in an aqueous and strongly acidic medium and comprises the application of an electrical feed signal formed of an alternating current superimposed on a direct current where the alternating current AC is in a range between 400 and 600 A/m 2 and is...
