In order to use energy efficiently in electrorefining and electrowinning operations, BAT is to use a combination of the techniques given below.

TechniqueApplicability
aApply insulation and covers to electrolysis tanksGenerally applicable
bAddition of surfactants to the electrowinning cellsGenerally applicable
cImproved cell design for lower energy consumption by optimisation of the following parameters: space between anode and cathode, anode geometry, current density, electrolyte composition and temperatureOnly applicable for new plants and for major upgrades of existing plants
dUse of stainless steel cathode blanksOnly applicable for new plants and for major upgrades of existing plants
eAutomatic cathode/anode changes to achieve an accurate placement of the electrodes into the cellOnly applicable for new plants and for major upgrades of existing plants
fShort circuit detection and quality control to ensure that electrodes are straight and flat and that the anode is exact in weightGenerally applicable
