ALCOA ALUMINUM PRODUCTION EDUCATIONAL FILMS BAUXITE MINING, REFINING & SMELTING 55284

This series of three films produced by ALCOA to educate the public about the aluminum industry focuses on the production of aluminum. The films discus Bauxite mining, refining, smelting, and delivery. The various aspects of the production of aluminum are shown including Bauxite Refining (:09), Smelting of Aluminum (5:30), and Aluminum Fabricating Process (10:10).

The Bayer process shown is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30–54% aluminium oxide, (alumina), Al2O3, the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.

Alcoa Corporation (from Aluminum Company of America) is an American industrial corporation. It is the world's fifth largest producer of aluminum, with corporate headquarters in New York City. From its operational base in Pittsburgh, Pennsylvania in the United States, Alcoa conducts operations in 10 countries. Alcoa is a major producer of primary aluminum, fabricated aluminum, and alumina combined, through its active and growing participation in all major aspects of the industry: technology, mining, refining, smelting, fabricating, and recycling.

On November 1, 2016, Alcoa Inc. split into two new entities: Alcoa Corporation, which is engaged in the mining and manufacture of raw aluminum, and Arconic, which processes aluminum and other metals. In April 2017, Alcoa announced it will move its headquarters back to Pittsburgh effective September 1.

Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
