    (PDF) GOLD ELECTROWINNING FROM CYANIDE SOLUTION;

    Electrowinning operations forms a critical part of Gold recovery; one of the earliest uses was in 1807, when the english chemist Humphry Davy obtained sodium metal in elemental form by the electrolysis of molten Sodium Hydroxide and in 1842, Henry Fox plated gold on electrodes of a galvanic cell (Shreir, 1963).The process of electrowinning ...

    Electrowinning

    Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4 The overall reaction is the combination of two electrochemical half reactions. The cathodic reaction
