The Production of Beryllium | SpringerLink
Abstract. The main source of beryllium in commercial deposits is beryl, Be 3 Al 2 [Si 6 O 18 ]. Beryl is generally found in pegmatites or micaceous greisens and is therefore mainly associated with feldspar, quartz, and micas. Other sources of beryllium are bertrandite, Be 4 (OH) 2 Si 2 O 7, and minor minerals such as chrysoberyl, Al 2 BeO 4 ...
Beryllium: genotoxicity and carcinogenicity
Workers are exposed to beryllium containing dusts during the crushing and grinding of ores, to soluble Be salts during extraction of the metal from the ore, and in the machining of beryllium metal and alloys [3]. Beryllium hydroxide is used in the production of Be oxides, the pure metal, and copper alloys.

Utah, is the only commercial beryllium extraction and production plant operating in the Western world.6 The Delta plant uses both beryl and bertrandite ores as inputs for the production of beryllium hydroxide. While the bertrandite ore is mined on-site using open-pit methods, the beryl ore is imported primarily from Brazil. However, beryl
Beryllium Fluoride
Beryllium fluoride ( BeF2 B e F 2) is a white solid being used as the principal precursor for the manufacture of beryllium metal. The production of beryllium is done by the reduction of BeF2 B e F 2 at 1300°C with magnesium in a graphite crucible: In order to obtain BeF2 B e F 2 beryllium ores (mainly bertrandite) are converted into …
