Electrowinning - an overview | ScienceDirect Topics

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 ...

Elution and Carbon Reactivation - Resource book

The gold can then be removed from the solution by electrowinning onto steel wool cathodes (refer 'Electrowinning and Smelting' module). As well as stripping the gold from the carbon, the elution process incorporates an acid wash stage, which removes inorganic foulants from the carbon. Foulants reduce the activity, and hence

Elution and electrowinning of gold from gold-selective ...

Electrowinning is compatible with the elution technique and provides a simple and effective method of recovering the gold from the eluate. The composition of the eluate does not affect the electrowinning efficiency much and it is therefore possible to operate both the elution and the electrowinning at their optimum efficiency.
