silver electrowinning in the new 174 cell

Electrowinning 102: Electrowinning of Silver

An additional benefit of silver recovery with emew electrowinning is that the electrowinning cell doesn’t have to be opened in order to harvest the metal. Silver will have a powdery form and the deposit is automatically flushed out of the cell to a secure collection vessel. Not only does this facilitate metallurgical accounting but also increases security and minimizes losses.

Electrowinning - Wikipedia

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 ...

Lead-silver anode behavior for zinc electrowinning in ...

AbstractIn recent years, a renewed interest in studying the electrochemical corrosion behavior of lead anodes during zinc electrowinning is probably due to the particularly high sulfuric acid concentrations in zinc electrolyte where lead alloy anodes have high cell voltage and high corrosion rate of lead. The high corrosion rate of lead alloy resulted in Pb contamination on zinc deposit.
