Reduction of production costs is a major consideration for aluminium producers particularly at Egyptalum. The average cell age at Egyptalum is 65 months. However, there are many cells that reached 100 months age and still work efficiently. This paper presents a case study of repairing and restarting a cell which failed at 28 months age. The paper aims at extending the cell life and reducing long term costs of depending on the potline. This cell failed through the collector bar connection that suffered damage from the aluminium metal. The cell was shut down. Then, the metal was tapped out and cell was left to cool. After that, the cathode surface was cleaned, and part of the cathode was also removed to enable fixing of the damaged collector bar. The hole and cathode surface were repaired with ramming paste, and the cell was preheated and restarted successfully.
