Beryllium is found in over 100 minerals, but most are uncommon to rare. The more common beryllium containing minerals include: bertrandite (Be 4 Si 2 O 7 (OH) 2), beryl (Al 2 Be 3 Si 6 O 18), chrysoberyl (Al 2 BeO 4) and phenakite (Be 2 SiO 4).Precious forms of beryl are aquamarine, red beryl and emerald.eryllium is most commonly extracted from the mineral beryl, which is either sintered using an extraction agent or melted into a soluble mixture. The sintering process involves mixing beryl with sodium fluorosilicate and soda at 770 Â°C (1,420 Â°F) to form sodium fluoroberyllate, aluminium oxide and silicon dioxide.
