Scale-up effects in modelling a full-size zinc ...

The scale-up of a mathematical model of a (10 dm3) pilot-plant zinc electrowinning cells is considered. All scale-up effects considered were relatively small in magnitude and their inclusion required only readily available full-size cell data. Excellent agreement was obtained between the model predictions and experimental results from an (instrumented) operational full-size cell.
