Electrorefinement, polyvalent metals

Ion-Metal Film Systems in Processes of Electrodeposition and Electrorefinement of Polyvalent Metals... 

That is, the expected behaviour of an anodic FS with low ionic (high electronic) conductivity has to be similar to a cathodic FS with low electronic (high ionic) conductivity. This consideration leads to a rather pessimistic conclusion practical employment of electrorefining process of a polyvalent metal in a long-time scale should appear to be a hard task if the FS would possibly form both at the cathode and at the anode.
