Alumina from Nonbauxitic Resources.
Proc Internat Committee for the Study of Bauxite Alumina and Aluminum Iscoba-aim Conf :12 pages
Although the United States produces nearly one-third of the world's primary aluminum, it must import more than 90 percent of the bauxite and alumina needed. To test and improve various raw material- process technology alternatives to the Bayer-bauxite process for alumina production, the Bureau of Mines is engaged in an extensive research and development effort. Information thus obtained will be used for decisionmaking on further large-scale testing of the process showing the greatest potential for producing alumina from a domestic nonbauxitic resource. The paper discusses recent research in the Bureau's alumina miniplant project, miniplant support research, and contract studies leading to the preliminary design of a 20-ton-per-day alumina pilot plant.
