Abstract
The materials of experimental research on alumina liquor precipitation kinetics in system Na2O – K2O – Al2O3 – H2O using carbonated alumina hydroxide as a seed are presented. Particle size distribution (PSD) analyses of settling products are given. Correlation link of alumina liquor decomposition degree and average median diameter of received aluminum hydroxide are shown.
