  • Elution and electrowinning of gold from goldselective

    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 The feasibility of elution with simultaneous31/03/2016· One bed volume (thirty minutes) into the elution stage the eluate pump is started and pregnant solution from the eluate tank, is pumped up into the electrowinning cell on the first floor of the goldroom It then flows back into the eluate tank As the solution flows through the electrowinning cell, gold is plated on to the steel wool cathodes This recirculation processAARL Carbon Stripping System Operation: ElutionElution can be improved by an increase in the thiourea concentration, the acid concentration or the temperature With an eluant containing 1 M thiourea and 05 M H 2 SO 4 at 60 °C, elution efficiencies of more than 996% can be effected within four or five bed volumes of eluant Using this elution strategy, the resin is easily stripped to below 100 g/t of residual goldElectrowinning an overview | ScienceDirect Topics
