Abstract
Currently, aluminum smelters require alumina of higher quality in terms of physical properties, so many studies are aimed at obtaining sand alumina. The method of obtaining sand alumina proposed by the St. Petersburg Mining Institute is considered. The influence of seed coarseness on the formation of productive alumina is considered. The influence of seed coarseness in the Bayer method and in the method of sintering with carbonization of aluminum hydroxide is studied. The proposed method of alumina production is at the stage of scientific research, so the introduction into the technology is not yet discussed.
