Abstract
The results of investigations on the ammonization with nitric acid extract of kaolin clays from the Angrene deposit, calcined at 650-700 °C are presented. It is shown that phase aluminum it is absent from the liquido at pH above 4,5 nitrate and the liquid phase consists mainly of ammonium nitrate. Washing the precipitate of aluminum and iron hydroxides allows to obtain mixture of aluminum and iron hydroxides with content of 98,00% Al(OH)3 and 1,70% Fe(OH)3 in terms of dry matter. The viscosity is changed from 1,012cPa to 0,553 cPa at this conditions
