Abstract: The results of the experimental study of the effect of calcium-containing reagents on the degree of leaching of Timanian deposit bauxites by a parallel method of Bayer sintering are presented. The phase composition of the interaction products is determined by the XPA and EDAX methods. The formation of calcium hydoxysilicate in red mud is found.
Keywords: alumina production, leaching, calcium oxide, calcium hydrosilicate.
