The anode reaction and current density of the electrowinning of Sb from jamesonite concen- trate have been investigate.High anodic current density seems to be the major reason for high energy consumption,air pollution by alkaline mists in workshop as well as poor quality of deposition.A series of steps,such as absorption,phase formation,ageing of passivated films etc.,were found to be involved during the anodic passivating process of Fe in NaOH solution. A new anodic material Fe/Ni/Co_3O_4 was developed so as to save the d.c.electric energy over 160 kWh/t of Sb.
