The invention relates to the improvement in the quality of cathodes produced in an electrolysis process. The surface of a cathode lifted from the cell during the cathode cycle is photographed and the physical quality of the cathode can be investigated in real time by means of equipment based on image- analysis. On the basis of the quality of the cathode surface, it is possible to monitor and control the electrolysis conditions in order to improve the quality of the cathode. The method is extremely suitable for the electrolytic purification of copper.
La présente invention a trait à l'amélioration de la qualité de cathodes produites dans un processus d'électrolyse. On effectue une prise d'image de la surface d'une cathode prélevée à partir d'une cellule durant le cycle cathodique et on peut examiner la qualité de la cathode en temps réel au moyen d'un matériel basé sur l'analyse d'images. En fonction de la qualité de la surface de la cathode, il est possible de surveiller et de contrôler les conditions d'électrolyse afin d'améliorer la qualité de la cathode. Le procédé convient parfaitement à la purification électrolytique du cuivre.
