The toxic effects of beryllium most commonly occur due to occupational exposure Beryllium is a metallic element used in many industries, including electronics, high-technology ceramics, metals extraction, and dental alloy preparation There are two forms of beryllium.
About Beryllium Properties and its Uses
When compared to the ancient histories of metals such as gold, copper and lead, beryllium is a relative newcomer Though beryllium was discovered in the late 18th century, its unique properties and commercial value were not recognized until the 1920s.
There is only one integrated manufacturer of beryllium: Brush Wellman Inc of Cleveland, Ohio Brush Wellman operates a bertrandite ore mine at Spor Mountain in Utah, and a mill in Delta, Utah to convert the ore to refined beryllium hydroxide Final extraction is performed at a.
BERYLLIUM AND BERYLLIUM COMPOUNDS
Beryllium and beryllium compounds were considered by previous IARC Working Groups in 1971, 1979, 1987, and 1993 (IARC, 1972, 1980, 1987, 1993) Since that time, new data have become available, these have been incorporated in the Monograph, and taken into consideration in the present evaluation.
Beryllium Hydroxide Facts, Formula, Properties, Uses
Beryllium hydroxide, also known as hydrated beryllia and beryllium dihydroxide, is a metal hydroxide that has amphoteric properties (behaves both as an acid and base) and chemically represented by Be(OH) 2 [1, 2]The pure beryllium hydroxide occurs naturally as the rare, orthorhombic mineral behoite, and very rare monoclinic clinobehoite .

Beryllium (Be), a metallic element, belongs to Group IIA of the periodic table and has an atomic weight of 9012 and an oxidation state of +2 (US EPA, 1987a; Budavari et al, 1989) Beryllium occurs naturally in the earth's crust at concentrations ranging from 2-10 ppm.
Beryl: The Gem Mineral of Emerald, Aquamarine, Morganite
The extraction of beryllium from beryl is very costly, and as long as bertrandite is available in large amounts, beryl will be a minor ore of that metal Small amounts of beryl, mostly produced as a by-product of gemstone mining, are still used to produce beryllium The major economic interest in beryl today is its use as a gemstone.
extraction beryllium role
Beryllium - Wikipedia The extraction of beryllium from its compounds is a difficult process due to its high affinity for oxygen at elevated temperatures, and its ability to reduce water when its oxide film is removed The United States, China and Kazakhstan are the only three countries involved in the industrial-scale extraction of beryllium.
BERYLLIUM AND BERYLLIUM COMPOUNDS

Beryllium-Technology, Applications, Patent, Properties
At its mining site in Delta, Utah, Brush Wellman treats bertrandite ore using a counter-current extraction process to produce beryllium sulfate, BeSO4 A second route, using the Kjellgren-Sawyer process, treats the beryl ore and provides the same beryllium sulfate intermediate , Properties of Beryllium Loaded Plastic Films;.
WebElements Periodic Table » Beryllium » the essentials
Its extraction from ores is complex The mineral beryl, [Be 3 Al 2 (SiO 3) 6] is the most important source of beryllium It is roasted with sodimu hexafluorosilicate, Na 2 SiF 6, at 700°C to form beryllium fluoride This is water soluble and the beryllium may be precipitated as the hydroxide Be(OH) 2.
Chemical properti In many of its properties, lithium exhibits the same characteristics as do the more common alkali metals sodium and potassium Thus, lithium, which floats on water, is highly reactive with it and forms strong hydroxide solutions, yielding lithium hydroxide (LiOH) and hydrogen gas.
Electrolytic Extraction of Beryllium-oxide from Beryl
Electrolytic Extraction of Beryllium-oxide from Beryl P B CHAKRAVARTI AND T BANERJEE Beryllium has of late come into prominence because of its immense value as an alloying element in some binary and ternary non-ferrous alloys The most important use of this metal is in atomic reactors where it acts as a moderator for slowing down fast neutrons.
Beryllium Extraction and Beneficiation
Beryllium Processing & Extraction Problem Beryl, the principal Beryllium mineral, is found generally in pegmatites associated with mica, feldspar, and quartz Its specific gravity is almost identical to quartz and feldspar, thus ruling out the possibility of gravity separation methods.
