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
