2000-1-1 · An electrowinning unit has three main components: 1) electrolytic cell; 2) rectifier; and 3) pump. An electrolytic cell is a tank in which cathodes and anodes are typically arranged in alternating order (Fig. 1). The cathodes and anodes are attached to their respective bus bars, which supply electrical potential to the unit.Effect of fluid density on flow in bagged electrowinning cells1987-2-1 · 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.
