cathode of that cell, which acts as a filter (see Figures 2 and 3). Thus, the gold particles are in electrical contact with that electrode. Since secondary electrowinning may also be carried out simultaneously in that cell, the gold from both sources is effectively combined at the cathode. However, initially the EWEF cell was used on its own to
12.3 Cell Voltage Electrowinning cells are operated in electrical series as shown schematically in Fig. 12.2. Each cell is subjected to the same current as supplied by a rectifier. The voltage of the system is the sum of the series of cells and resistances of the electrical distribution system (e.g., bus bars). The voltage of the ...
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.
