Beryl Highgrade beryl specimens are found at many pegmatite locations throughout western Maine. One noteworthy spot is the Bumpus Quarry in Oxford County. There have also been giant beryl crystals found that were huge, with one recorded discovery as large as 18 tons! Beryl comes in a variety of colors, most commonly in shades of blue or green.
ZIMBABWE MAIN ECONOMIC MINERALS GOLD Gold mining and exploration in Zimbabwe has been going on from ancient times and it is estimated that a third (about 700 tonnes) of all historical gold production was mined locally from the seventh century until the introduction of mechanized mining methods with the arrival of Europeans about a century ago.
The only known beryllium occurrences in Wyoming are berylhosting pegmatites in several mountain ranges. Between 1928 and 1940, small quantities of beryl (Be 3 Al 2 Si 6 O 18) and tantalite (Fe, Mn)(Ta, Nb) 2 O 6 were mined from the Whippet No. 1 and No. 8 claims in the Copper Mountain district of the Owl Creek Mountains.

The beryl ore is melted in industrial furnaces, solidified and crushed, then treated with sulfuric acid to produce a watersoluble sulfate. The bertrandite ore is crushed, made into slurry and treated with sulfuric acid to form a sulfate.
Beryl is a most alluring and popular mineral. It occurs in a diversity of colors, and has several important gemstone varieties. The green variety, Emerald, is one of the most precious green Beryl with a deep green color is called Emerald; light green Beryl is simply quot;Green Berylquot; (or Heliodor if it has a yellowish color.)Aquamarine, another important gemstone, is the greenishblue to

Beryl (/ b r l / BERRl) is a mineral composed of beryllium aluminium cyclosilicate with the chemical formula Be 3 Al 2 Si 6 O 18. Wellknown varieties of beryl include emerald and occurring, hexagonal crystals of beryl can be up to several meters in size, but terminated crystals are relatively rare. Pure beryl is colorless, but it is frequently tinted by
commonly associated with feldspar mining where the beryl is recovered by handsorting of crushed pegmatite. In contrast, bertrandite can be extracted by surface mining methods and processing involving acid treatment and purification. The gem members of the beryl family are morganite (pink), heliodor (golden), aquamarine (pale blue to bluegreen) and emerald (brilliant green).
Beryl, a group of beryllium aluminum cyclosilicate mineral with the chemical formula Be 3 Al 2 (SiO 3) 6 is categorised as semiprecious gemmineral with special beauty (colour) and physical properties making them suitable for adornment and decorative purposes. Beryl, the most common
