Electrorefining is a much more common process than electrowinning and such plants occur throughout the world on scales between 1000-100,000 ton/year. Usually they are part of a larger operation to separate and recover pure metals from both scrap and primary ores. Therefore, the process must be designed to handle a
A unique feature of the electrowinning process is acid generation. As a result, acid can be recycled or recovered from the metal depleted electrolyte. In particular, high concentrations of acid can be produced in an emew cell due to their unique ability to deplete to very low concentrations of metals (< 1 g/L).

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 ...
