Abstract

Materials of the kinetic analysis of multistage mass-transfer process at decomposition of aluminate solutions in alumina production are presented. It is shown that in the mass-transfer equation concentration indicators which take into consideration distribution of reagents and products in a diffusive layer can play a role of effective concentration. Results of experimental researches of crystallization streams on a various fraction structure are resulted.
