The current process using Moebius cells has a turnaround time of 4872 hours from the time the silver (and gold) enters the electrorefinery as impure anode, until the gold is recovered from the spent anodes. Furthermore, the inventory required to produce 500 kg/d of pure silver is three times this amount, that is to say 1500 kg/d.
Electrowinning is a very convenient and robust way to directly recover dissolved metals such as copper, silver, gold, nickel, cobalt, and tin from their aqueous states in a particular electrolyte.

May 24, 2016· Electrowinning is a widely used technology in modern metal recovery, mining, refining and waste water treatment applications. Electrowinning is one of the oldest electrolytic processes known and was first introduced in 1807 by English chemist Humphry 66 long years the first commercial refinery Balbach and Sons Refining and Smelting Company adopted the electrowinning .
Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4 The overall reaction is the combination of two electrochemical half reactions. The cathodic reaction .
Electrowinning ScienceDirect Electrowinning is most often used to recover gold and silver from eluates produced by the elution of activated carbon. This chapter discusses the operation of the electrowinning process that differs depending on the elution procedure that is used. 22November
An electrowinning cell of novel design has been described by Treasure (2000).Named as EMEW R cell, it consists of a cylindrical in place of planar electrodes. The outer tube is the cathode and the inner one is anode. The diameters of the electrode tubes are sized according to the particular application to minimize cell voltage for a given solution chemistry.
The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold. The process of electrowinning simply involves passing an electric current through the electrolyte (eluate).
