Jan 01, 2016 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 amp Electrowinning

Based on the information you provided, the alternative reagent to cyanide is called GoldMax. My suggestion is to consider the AARL elution process (more temperature, more pressure). In this kind of elution, electrowinning is performed on the complete batch of eluate produced by a single pass through the elution column.

AARL Carbon Stripping System Operation Elution

Mar 31, 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.
