d. Aluminum reduction by the electrolytic process is shown in Figure 2-10. The
removal of oxygen from alumina is performed electrolytically; large amounts of
electric power, carbon, cryolite, and alumina are required to produce aluminum.

(d) Large and small storage silos (Annotations 4 and 5).
(f) Casting building (Annotation 6).
(g) Fluorine recovery units will be small boxlike objects located between
pot lines and connected to them by pipes.
