Extraction of beryllium from beryl

WebBeryllium metal is most commonly extracted from two ores: beryl and bertrandite. Beryl ore contains roughly 2-4% beryllium, while bertrandite ore typically contains less than 0.5% beryllium. The refining processes of beryl and bertrandite are quite similar and can be carried out together. WebThe main source of beryllium in commercial deposits is beryl, Be3Al2[Si6O18]. Beryl is generally found in pegmatites or micaceous greisens and is therefore mainly associated with feldspar, quartz, and micas. ...

WebThe mineral beryl (Be3Al2(SiO3)6) has the most abundant phase with industrial value for extracting a critical metal—beryllium. Due to multi-stage, fluid-induced growth, individual beryl grains may yield complex geochemical records, revealing variations in the oxygen isotopes of the fluids from which they crystallize. Secondary ion mass spectrometry … WebWithin the cores of stars, beryllium is depleted as it is fused into heavier elements. Beryllium constitutes about 0.0004 percent by mass of Earth's crust. The world's annual beryllium production of 220 tons is usually manufactured by extraction from the mineral beryl, a difficult process because beryllium bonds strongly to oxygen.
