Unloading Alumina

Alumina is the raw material used to produce primary aluminum. Unloading roles help receive, move, and manage this essential material as it enters the facility.

Potroom

The potroom is where electrical current transforms alumina into molten aluminum. Employees support the equipment, systems, and daily operations that keep reduction cells running.

Making Anodes

Carbon anodes are manufactured before they enter the smelting process. These roles support material preparation, forming, and production activities that supply the potroom.
