Technique
Applicability
a
Apply insulation and covers to electrolysis tanks
Generally applicable
b
Addition of surfactants to the electrowinning cells
Generally applicable
c
Improved cell design for lower energy consumption by optimisation of the following parameters: space between anode and cathode, anode geometry, current density, electrolyte composition and temperature
Only applicable for new plants and for major upgrades of existing plants
d
Use of stainless steel cathode blanks
Only applicable for new plants and for major upgrades of existing plants
e
Automatic cathode/anode changes to achieve an accurate placement of the electrodes into the cell
Only applicable for new plants and for major upgrades of existing plants
f
