Scholarcy highlights

  • Anode spike crises have a deleterious effect on current efficiency to the point of jeopardizing smelter operation
  • All the time spent with a spike under an anode is a period where current is lost, and the longer the spike remains present, the more serious are the mid-term consequences for the reduction process
  • A new tool based on anode current measurements, combined with machine learning, has been developed and tested
  • It is an effective way of detecting many of these spikes, usually a few days before they become obvious
  • This article describes the development of the tool and the first results obtained on industrial cells
