Abstract
The invention relates to a method for electrowinning a metal from an electrolyte in an electrowinning cell that comprises an electrolysis tank, one or more anodes, and one or more cathodes, which anodes and cathodes are housed in the electrolysis tank. The method comprises supplying sulfur dioxide to the anode to depolarize the anode process and to reduce the energy consumption of the electrowinning cell.
