The TMS 2012 Industrial Aluminum Electrolysis Course includes a tour of the Rio Tinto Alcan –Grand Baie Works, in Quebec on Wednesday, September 12. The Grande-Baie Works was established in Quebec, Canada in1980 and employs approximately 665. The smelting technology features 384 prebake-anode reduction cells (P-155). The Grand-Baie Works has a 200-fleet maintenance garage, a 14-bridge crane workshop, a high voltage station, an energy center and stores $10 million (Canadian) in inventory.
