Beryllium is extracted from the beryllium silicate ore by either sintering or melting into a soluble mixutre. The sintering process uses sodium fluorosilicate and soda at around 770 °C (1,420 °F) to create sodium fluoroberyllate which is then decomposed to beryllium hydroxide with water.
Beryl, the principal Beryllium mineral, is found generally in pegmatites associated with mica, feldspar, and quartz. Its specific …

The interaction of beryllium minerals with ammonium fluoride is described by the following reactions: (1) Be 2 SiO 4 + 7NH 4 HF 2 → 2(NH 4) ... After phase separation, carbon was washed on the filter with warm water at 45–50 °C, the amount of wash water was 50 mL. Wash water and solution were mixed together and analysed for …
These include most sulfides and sulfosalts, many beryllium minerals, anatase, barite, bastnaesite, carbon, graphite, rutile, topaz, zircon, and doubtless others not yet investigated. This fortuitous contrast in solubility is the basis for a separation method that offers some useful advantages over physical methods of mineral separation.
The solvent-extraction of beryllium from aqueous mineral acid solutions by a variety of mono- and di-alkyl esters of phosphoric acid has been studied by using the radioactive isotope 7Be.
Separation of beryllium(II) and aluminium(III) by solvent extraction using Bis-2 ethylhexyl phosphoric acid [HDEHP]
A process and reagents are described for separating beryllium silicate concentrates by flotation from oxidic minerals. The process is especially suitable for the separation of phenacite and bertrandite present in ores with complex gangue compositions. The ore is ground and subjected to acid pretreatment, then conditioned by the addition of pH …
See also: Category:Beryllium minerals. The beryllium concentration of the Earth's surface rocks is ca. 4–6 ppm. Beryllium is a constituent of about 100 out of about 4000 known minerals, the most important of which are bertrandite (Be4Si2O7(OH)2), beryl (Al2Be3Si6O18), chrysoberyl (Al2BeO4), and phenakite (Be2SiO4).
