ELECTROWINNING CELLS There are a wide variety of configura-tions of electrowinning cells, and the literature abounds with cell designs based on different electrode forms. Cell designs may be classified into two main groups: rectangular tank cells and cylindrical electrode cells. Rectangular tank cells are the most common commercial cell type. They

In general, plant operation data show that E is normally two or three times larger than E cell. For example, in deposition of copper, a potential drop of 2.3 V per cell occurs although E cell is only 0.89 V. Since resistivity of the electrolyte decreases with an increase in temperature, electrolytic tanks are operated at about 40 – 50 °C.
