Abstract
This study reviews the minimum study necessary to characterize Bayer alumina for the reduction to aluminum. Several industrial-grade aluminas from a smelter in Spain are characterized in terms of surface area, gibbsite and alpha-alumina contents, bulk density and pycnometer density. Characterization results are correlated with particle size data, and different methods to measure those properties are reviewed. Finally, a minimum number of physico-chemical properties are selected to describe accurately and economically the quality of smelting-grade aluminas.
