Abstract

Process for the preparation of pure magnesium oxide from crude magnesite and/or other starting materials containing magnesium carbonate, magnesium oxide and/or magnesium hydroxide, which are reacted with hydrochloric acid to form a solution of magnesium chloride, purifying then this solution, after which the magnesium chloride is transformed by thermal decomposition into magnesium oxide and hydrogen chloride, characterized in that for the dissolution of magnesium chloride, which is intensively stirred, and because it is a match solution with the hydrochloric acid introduced, for the formation of magnesium chloride and the magnesium chloride is removed in dissolved form for further treatment.
