electrowinning process for extraction of gold from e - Capabuild
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 ...

Pyrometallurgy: Roasting, Smelting, Refining & Electrowinning
E/W single pass efficiency is critical for Zadra because gold not recovered is then re-circulated back to the elution column, slowing down the elution rate. Eluant flowrate is not too critical in the 2-4 BV/h range. You should be achieving optimum elution with about 30 BV of eluant through the column (15h at 2BV/h).

How does electrowinning work? Explained by FAQ Blog
How does gold electrowinning work? 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 solution. In cyanide solutions, gold is present as a stable auro-cyanide complex anion with a relatively high cathodic potential (E0).
