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).

Over the past 25 years, emew has continued to push the boundaries of electrowinning by continuously improving the emew technology with advanced designs for plating, powder, polishing and hybrid systems including a suite of complementary clean technologies catering ...
containing high levels silver that direct electrowinning using EMEW has proved to be a viable and cost efficient alternative and can be used in the place of the Merrill Crowe process shown in Figure 2.
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.
Nov 23, 2018· Offering the original 'vortex' emew electrowinning and green technologies for a variety of applications in mining, refining, and environmental sectors. Silver refining demands technology that can ...
Electrowinning Cell Process Eluates containing soluble gold and silver from either a ZADRA or an AARL type elution are suitable for recovery in the Kemix Electrowinning cell. Electrowinning is a process used to recover metals (eg. gold and silver) from concentrated solutions by applying a voltage across electrodes immersed in a concentrated ...
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.

To meet these challenges, emew's combination of purpose built process solutions coupled with proven technology enable valuable metals such as Copper, Silver, Gold, Nickel, and Cobalt to be recovered from complex, mixed-metal residues, sludges, slags, oxides, scrap, e-waste, spent Li-ion batteries, and more.
Direct electrowinning is pushed to the extreme with emewPolish. Using the same concept of high-efficiency emew electrowinning equipped with a sophisticated, proprietary high surface area cathode, this type of emew cell can recover metals down to less than 5ppm.
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 .
