Electrowinning rectifier

1. Electrowinning process introudction:

      Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The resulting metals are said to be electrowon.


2. Suitable electrowinning metals

Copper, lead, gold, silver, zinc, aluminium, chromium, cobalt, manganese, and the rare-earth and alkali metals.
