  • Electrolytic Refining Mining Fundamentals
    IntroductionElectrolytic Refining of MineralsReferencesElectrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. In the electro-refining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode. Both the cathode and anode are dipped in an electrolytic cell containing an aqueous solution of the metal salt. Upon the application of electric current of a suitable voltage, pure metal is deposited at the cathode by the dissolut...
  • Electrowinning Copper Chemistry Tutorial

    Electrowinning Copper Key Concepts. Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably).
