Аmmonium fluoride processing of beryllium raw materials

Alexander Dyachenko, Roman Kraydenko, Lev Malytin

Research output: Chapter in Book/Report/Conference proceedingConference contribution


A new method of processing beryllium raw materials based on interaction of beryllium mineral with ammonium fluoride was developed. Possibility of extracting ammonium tetrafluoroberyllate from bertrandite and phenakite minerals is proved. The developed technology allows replacing the outdated sulfate technology developed by Materion Corporation.
