Electrowinning | Gekko

Electrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the cathodeKemix - Electrowinning,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 The positive terminal from the rectifier is connected to the anode where the oxidation reactions occur and electrons are generatedSelective Electrowinning of Silver and Gold From Cyanide ,and Au bullion4 It would be advantageous if the electro­ winning process could be made more selective for re­ moving only the Ag and Au and leaving the Cu behind in the cyanide solution This would produce a metal product that contained little Cu Such a product would be cheaper to refme since refinery charges increase with increasing Cu
