Effect of sulfurdioxide on cobalt electrowinning

The study focused on the use of sulfurdioxide on the cobalt electrowinning and its advantages over conventional electrowinning cell practice are reported. The results indicated that addition of sulfur dioxide in the electrowinning cell reduces the sludge formation with small increase in the current efficiency. SEM response showed an improvement in morphology and DSC analysis gave an idea of the microstructure which is close to FCC lattice system.
