A novel porous Pb–Ag anode for energy-saving in zinc

2010-4-1  A new method for the preparation of large size porous anodes has been developed, called counter-gravity infiltration; and four kinds of porous Pb–Ag anodes with different pore sizes were prepared. The anodes were tested in a pilot plant for 24 days with the electrolyte drawn from the zinc electrowinning plant. The results show little impact on the electrowinning system.

The importance of cathode zinc morphology as an

The preferred conditions generated by the small scale tests were successfully implemented in pilot plant trials using a full sized electrolytic cell producing 0.5 t per day of zinc. Overall, the tests confirmed the expectation that there is a strong correlation between current efficiency and the morphology of zinc

A set of (95) equations forming a dynamic, nonlinear model of an industrial pilot-plant scale zinc electrowinning cell fed with high purity electrolyte is presented. Only the solution of the steady-state model is considered in this paper. Values for unknown model parameters have either been obtained from the literature or else estimated using experimental data taken from the pilot-plant cell.
