Beryllium Extraction and Beneficiation

Apr 12, 2016  Beryllium Processing Extraction Problem. Beryl, the principal Beryllium mineral, is found generally in pegmatites associated with mica, feldspar, and quartz. Its specific gravity is almost identical to quartz and feldspar, thus ruling out the possibility of gravity separation methods. Beryl is harder than quartz.
