TO THE PROBLEM OF ALUMINUM HYDROXIDE CRYSTALLIZATION FROM ALUMINATE SOLUTIONS

摘要

In laboratory conditions the process of agglomeration of alternate corpuscles of aluminum hydroxide with effective diameter less than 10 microns in aluminate solutions obtained as a result of nepheline processing to alumina by the sintering method is researched. The influence of temperature and amount of 《priming》 on growth rate of crystals and efficiency of agglomeration are studied. The optimal parameters for an agglomeration of small fractions, separated from production aluminum hydroxide manufactured on 《Achinsk alumina plant》 are defined.
