To reduce transportation costs of bauxite to alumina refineries and alumina to aluminium smelters RUSAL is developing effective alternative technology of alumina production from local non-bauxite ores.
Following the completion of the laboratory tests of the acid technology of alumina production, the miniplant tests were carried out. Parameters and consumption rates of the technology were determined for the stages of kaolin acid leaching, filtration and washing of silica residue, crystallization of aluminuim chloride hexahydrate and its calcination, rectification of hydrochloric acid. Corresponding chemical and physical processes were studied. Data for technology implementation in industrial scale were obtained.
