Abstract The methods for removal of Zn, Fe, Si, S and organic substances from alkali-aluminate solutions at proces sing by the compounds of Mg, Ca, NaS and electrolysis are discussed and the experimental results are presented. The conditions of the most effective removal of impurities from Bayer solutions, providing the manufacturing of hithquality alumina, are determined.
keywords Solutions of aluminium oxide production, removing of impurities, processing by magnesium and calcium compounds electrolysis of solutions.
