Improvements in the bipolar refining of lead are described, comprising maintaining a high current density controlled at a value such that the anode overvoltage will not exceed the value at which impurities dissolve and which is related to the internal resistance of the cell, together with periodic reversal of the polarity of the current applied to the electrodes. These improvements result in improved cell efficiency and in the formation of strong, coherent lead deposits which are easily stripped by mechanical means. |
