Abstract

In the production of alumina by the calcination of crystals of aluminium chloride obtained by saturating a hydrochloric-acid solution of aluminous material with gaseous hydrochloric-acid, the mother liquor is displaced from contact with the crystals by means of a concentrated solution of aluminium chloride, before they are removed from the saturation vessel. After the precipitation of the crystals, the aluminium-chloride solution is passed from below into the vessel containing the crystals, which latter, together with the aluminium-chloride solution, are withdrawn from the bottom and separated, for example by means of centrifugal action. The hydrochloric acid is recovered from the displaced mother liquor by distilling with sulphuric acid and is used for precipitating the aluminuim chloride or is dissolved in water for the dissolution of fresh aluminous material. The sulphuric acid is concentrated for re-use and may be periodically freed from iron sulphate, which is present as impurity, by cooling.
