 EMI2.1
 Contains 1 molecule of alkali to 1 molecule of beryllium oxide, i.e. H. the advantage of the process has been more or less impaired.



   While so far a separation of the beryl alumina from the alumina in the indicated sense has been ruled out by the literature cited above, a quantitative and technically useful method of separating the two earths is made possible by the present invention, in that it has been recognized that it is complete
 EMI2.2
 
1. In a mixture of hydroxides of alumina, beryl alumina and iron, which contains 20 tonnes of alumina, 10 parts of beryl alumina and 4 parts of iron, 100 parts by volume of 5N sodium hydroxide solution are added, the undissolved iron hydroxide is filtered off and treated with carbon or carbonic acid and sodium bicarbonate until all the baking soda resp.



    Sodium carbonate is converted into acid, carbonate of soda. The herd goes smoothly into solution, clay and iron remain undissolved. The beryl alumina solution is separated from the remaining precipitate and the heryl alumina is separated from this solution in solid form by heating, diluting or precipitating with alkali.



   2. The mixture of hydroxides given above is mixed with 62 or more parts of sodium carbonate and so much water that a 2-3 times normal solution is
 EMI2.3
   sodium carbonate is converted into sodium bicarbonate, whereupon proceed as under 1.



   3. The above mixture of hydroxides is mixed with 88 # 6 or more parts of sodium
