The Study of Method for Complex Processing Turgay Sub-Standard Aluminum-Containing Raw Materials
objects of the research are Kazakhstans 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℃,original solution K2Oconcentration 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℃,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
