The methods for removal of Zn, Fe, Si, S and organic substances from alkali-aluminate solutions at processing 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 high quality alumina, are determined.
