...This is the greatest contribution to aluminum metallurgy since the Hall process of 1886-if it is cheap as the inventor says." So commented the Aluminum Co. of America on a new process for extracting alumina from common clay announced last week by Chemical Engineer Arthur W. Hixson of Columbia University...
Heretofore the only commercial source of alumina-the oxide from which the pure metal is produced-has been bauxite, about half of which is now imported from British and Dutch Guiana, since there are only some 13,000,000 tons of known high-grade bauxite deposits in the U.S.-about a three-year supply at the present rate of consumption...
...ruled on before he can make the final decision: whether to break Alcoa up. Three branches of law are involved: tariff law, patent law, the Sherman Act. The Government's charges were in twelve groups, for different branches of the industry: 1) bauxite; 2) water power; 3) alumina; 4) virgin aluminum, pig and ingot; 5) castings; 6) cooking utensils; 7) pistons; 8) extrusions and structural shapes; 9) foil; 10) miscellaneous fabricated articles; 11) sheet; 12) cables...

...make 1,400,000,000 lb. of aluminum a year, the nation will need 2,800,000,000 lb. of alumina (in addition to large amounts used raw by chemical and abrasives industries). With Alcoa's new alumina plant, U.S. capacity will be something over 2,000,000,000 lb. a year. About to be signed with Reynolds is a contract for another alumina plant which will add 200,000,000 lb. To make up part of the remaining alumina deficit, OPM recommended last week that still another 600,000,000 lb. of Government-owned capacity be added...
