    The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold. The process of electrowinning simply involves passing an electric current through the electrolyte (eluate). Electrons (electricity) pass from the cathode (negative electrode

  • REVIEWING THE OPERATION OF GOLD ELECTROWINNING CELLS

    To a great extent, the calculations made to size a standard gold electrowinning cells are based on data and models reported by Roger Paul of Mintek in SA. Extensive plant data collected and interpreted by Mike Costello (Australia) has been used to further enhance the methodology used to size common gold EW cells. Discussion presented is based on the “Mintek”-type cell and compared to the
