Abstract

Abstract The results are presented from an investigation into the effect of the Fe(III) and Fe(II) concentration on the current efficiency for copper electrowinning using the Chemelec cell. The results are from polarisation studies of acidic sulphate electrolytes containing Cu(II), Fe(II) and Fe(III). The mass transfer coefficients for these cationic species are determined, and the effect of using different anode materials on the overvoltage for the oxidation of Fe(II) and oxygen evolution is also examined.
