A process for the preparation of pure beryllium compounds from materials containing, in addition, alumina and silicic acid consists in converting the beryllium present into beryllium oxide insoluble in dilute acid, treating the reaction product with a dilute acid which is capable of forming soluble salts with ammonia alkaline earths and iron, separating the solution from un dissolved silica and beryllium oxide, and separating the two latter compounds.
