Pyroprocess Regarding the oxide electrowinning method, evaluation of safety design, such as rationalization of waste process and identification of countermeasures for accidents concerning electrowinning equipment proceeded, and, among the principal subjects, the elemental technology tests for MOX electrowinning coprecipitation and .
Operation of the electrowinning process differs depending on the elution procedure that is used. In the case of Zadra elution, where the electrowinning cell is in series with the elution column, the column and cell must be designed to elute and recover the gold by recirculation of the eluant until the gold content of the eluted carbon is low enough (<100 g/t) to be reactivated and returned to ...
In gold electrowinning process,when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, Au（CN）2ˉ is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution is process via ionization. At last, solid gold is attained.

Electrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution. Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the cathode.
Electrowinning and Smelting Resource Book. Electrowinning and smelting are the final stages of gold production. 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.
What distinguishes the lonnet most from other electrowinning systems is the expanded surface area cathodes and the unique solution flow design.. It has been reported to us that 60% – 80% of the free cyanide in a 500 gallon solution was destroyed in 48 hours of operation at 400 amps.
