Results of desalination siliceous minerals alkali-containing are presented by solutions. Testify that that decomposition kaolin occurs in thickness of the firm phase covered with crust hydroalumosilicate of sodium, without breaking its basic structure and without surplus of solvent. The dissolved surface remains to a constant that is one of conditions of applicability of the equation of Drozdova – Rotinjana.
