In Line Leach Of Gold Solution Electrowinning

Kemix - Electrowinning

Electrowinning Cell Process Eluates containing soluble gold and silver from either a ZADRA or an AARL type elution are suitable for recovery in the Kemix Electrowinning cell. Electrowinning is a process used to recover metals (eg. gold and silver) from concentrated solutions by applying a voltage across electrodes immersed in a concentrated solution.
