Abstract


The kinetics of the electrolytic Fe+2/Fe+3 oxidation, relevant to hydro-electrometallurgical processing, have been studied on lead, platinum, ruthenium oxide, iridium oxide and graphite anodes in ferrous sulfate-sulfuric acid solutions. The oxidation rate depends on ferrous sulfate concentration, solution temperature and degree of agitation. Potentiodynamic studies show that: a) the highest oxidation rate is obtained on platinum; b) lead is unsuitable as anodic material for the said reaction; c) the remaining anode materials show a similar and satisfactory performance.
