Abstract
In bagged electrowinning cells where there is gas evolution at the anode, such as the NiCl2 system, flow across a porous diaphragm bag is observed to occur predominantly from the bottom of the cell. A model based on a hydrostatic argument is proposed which can account for this phenomenon on the basis of bulk density difference between the catholyte and anolyte. Experimental evidence by means of visualization through acid‐base reactions shows good agreement with the model.
