Elution Electrowinning Difference

Electrowinning an overview ScienceDirect Topics

Elution was carried out at 60 °C for 6 h. At termination of elution, the difference between the gold concentration in the eluant entering and the eluate exiting the column was less than 1 mg/L Au. Elution profiles (eluate exiting the column) typical of the sodium benzoate-containing eluate are shown in

Chapter 33 Electrowinning ScienceDirect

Electrowinning is most often used to recover gold and silver from eluates produced by the elution of activated carbon. Some of the practical considerations involved in the design and operation of gold electrowinning cells are described in this chapter, including cell types, bullion removal, and special applications such as electrowinning from gravity concentrates, and sulfide oxidation filtrates.
