Abstract (en)
[origin: WO2017191458A1] The invention relates to an electrorefining cell and its use in a method of electrorefining of copper. The cell comprises: one or more electrorefining anodes comprising impure copper; one or more cathodes; an electrolyte containing copper sulfate and sulfuric acid; one or more electrowinning anodes; and one or more point-of-use power converters configured to supply current to the or each electrowinning anode whereby to control the copper concentration of the electrolyte when said cell is in use.
