USBurMines 1947 30mln sd loan 669.7 Jh-sh-c-ad A revision of "Nickel High-lights" Shows activities & operations in Canada and the United States which are essential to the production of the vitally important metal nickel and its alloys. Covers nickel mining, milling, smelting & refining. THIS IS ALUMINUM. USBurMines 1947 28mln * sd loan 669.7 Jh-sh-tr-^d Produced by Atlas Educational Pictures for Aluminum Co. of America The mining and preparation of aluminum ore and the fabrication of the metal and its alloys are related in an interesting manner. Opening with the mining of bauxite, the film depicts the crushing, washing, and drying of this material for shipment to huge mills where the alumina is extracted. Graphically the film shows the production of pure metallic aluminum In a reduction plant by the only known process— the passing of an electric current through a bath of alumina dissolved in melted cryolite. Following the pure metal from the electrolytic bath the picture demonstrates the versatility of aluminum, which can be worked and fabricated by every known process — casting, rolling, extrusion, forging, drawing, spinning, stamping, machining and welding UNFINISHED RAINBOWS. Modern 1942 36min sd color loan 669.7 Jh-sh-c-tr-ad Produced by Wilding Picture Productions for the Aluminum Co. of America "The aluminum industry is traced from Napoleon Ill's time to the present. EJarly experiments by Hall to find a cheaper way of processing aluminum and his efforts to find a market are shown. Hall's followers in the field have constantly opened up new flelds of use for the metal as in office furniture, electrical wire, train metal sheeting. A story of an industry, but the value of the film has not been impaired." Collaborator "The most beautiful film. Timely, Interesting. Unusual." Collaborator "A fascinating story of trials and success In the American way." Collaborator "One of the few films suitable for high school chemistry classes. Teaches a lot about career of research work or at least to appreciate the great labor that has given us our modern products." Collaborator "Objectionable since it gives little place to small industries. Good if taken with grain of salt. Technically good." Collaborator 671 Metals BRAZING CARBIDE TOOLS.
