Abstract

Results of desalination thermoactivated siliceous minerals alkali-containing are presented by solutions. Testify that at desilication bauxite it is observed gradual braking dissolution of a dioxide of silicon and alumina oxide at the expense of formation of a shielding layer. The increase in temperatures desalination roasting and the silicon module of initial bauxite leads to increase of factor of braking.
