Electrolytic Extraction of Beryllium-oxide from Beryl

Chakravarti, P B and Banerjee, T (1957) Electrolytic Extraction of Beryllium-oxide from Beryl. In: Symposium on Mineral Beneficiation and Extractive Metallurgical Techinques, Feb. 1957, NML, Jamshedpur.



Beryllium has of late come into prominence because of its immense value as an alloying element in some binary and ternary non-ferrous alloys. The most important use of this metal is in atomic reactors where it acts as a moderator for slowing down fast neutrons. It is obtained from the mineral beryl of which India is one of the principal prod-ucers. An electrolytic method for the extraction of bery-llium-oxide from beryl has been developed at the National Metallurgical Laboratory, which consists in first obtaining the beryllium in solution as a soluble beryllium salt and then electrolyzing this solution between two graphite electrodes in a diaphragm cell. A slurry containing the hydroxide of beryllium is obtained from the cathode comp-artment, which on washing, drying and ignition, gives the oxide.
