Abstract

Pure soda ash, caustic soda lye and carbonic acid suitable for liquefaction are produced from mineral sodium carbonate such as natron or trona. The mineral is heated with a metallic oxide such as ferric oxide adapted to remove carbon dioxide, and the carbon dioxide evolved is led into a concentrated solution of another portion of the mineral. The bicarbonate which is precipitated is dried by waste heat and calcined to give soda ash and carbon dioxide. Metallic oxide for re-use and caustic soda lye are obtained by lixiviation of the mass resulting from the heat treatment.
