Abstract
The Bureau of Mines characterized foreign and domestic bauxites and domestic high-alumina grogs with respect to chemical and mineralogical analyses and refractory properties. Domestic raw materials such as ferruginous bauxites, saprolites, and zunyite were evaluated as substitutes for imported refractory-grade bauxite (rgb). Available data on ferruginous bauxite reserves are insufficient to evaluate the potential of upgraded ferruginous bauxite as a rgb substitute. Saprolite deposits of the southeast were evaluated as a source of gibbsite, but results indicate that simple beneficiation procedures would not produce a suitable rgb substitute. Initial evaluation of a synthetic magnesium aluminate spinel produced from aluminum dross as a rgb substitute was encouraging.
