Electrolytic Refining - Mineral Processing Metallurgy

21/10/2017  The anodes used in refining base metals — nickel, copper, lead—by electrolysis usually contain gold, silver, platinum, palladium, etc., as well as selenium and tellurium in some amount. In every case, these metals, being less easily oxidized than the principal metal constituting the anode, are not dissolved by the electrolytic action, and remain at the anode in finely divided form. As the ...
