Metso will supply OAO Severstal with a complete rotary drying system for its iron ore plant upgrade project at the Olkon mine in Olenegorsk, Russia. The high-capacity single-line system will replace multiple existing rotary dryers. Metso’s delivery also includes a modern automation system, which will enable tighter control of the process. The high-capacity drying system will improve mine performance.
