ABSTRACT

objects of the research are Kazakhstan’s Turgay clay, studied of method for alumina and potassium metasilicate obtaining from Turgay sub-standard aluminum raw materials. Concluded that optimal conditions for the process of Turgay clay: reaction temperature 100°C, original solution K2O concentration to 300 g/dm3, reaction time 120 min, liquid-solid ratio of 3:1; optimized the conditions of digestion alumina concentrate: original Na2O solution concentration of 400 g/dm3, temperature 280°C, molar ratio CaO : SiO2 = 1. Recovery is 99.6 % of alumina digestion under this condition; crystallized solid phase components as Na2O·Al2O3·6H2O sodium hydroaluminate crystals. Extracted of alumina from solution of sodium hydroaluminate
