Beryllium is not found in large quantities as a free element, but is a component of many naturally occurring minerals. These minerals occur only rarely in significant exploitable deposits, and both this and the expense of extracting the element from ore contribute to its high cost.
Beryllium was considered a promising material for high-temperature nuclear reactors (carbon, of course, cannot be used). Beryllium was used as a neutron reflector to reduce the size of reactor cores. It is used in nuclear weapons for the same purpose. Metallurgy. Beryllium ores contain no more than 5% Be, because it is so light.

Highlights Simultaneous removal of beryllium and NH 4 + – N by biological aerated filter reactor was studied. High accumulation rates of beryllium inside the microbial cells was observed. The main removal mechanisms of beryllium were precipitation, complexion and bioaccumulation. N-oxidizing and metal-resistant bacteria were found in pilot-scale reactors.
The age or precipitation hardening results from the precipitation of a beryllium containing phase from a supersaturated solid solution of mostly pure copper. The precipitation occurs during the slow cooling of the alloys because the solubility of beryllium in alpha copper decreases with decreasing temperature.
Contributors; Beryllium fluoride ((BeF_2)) is a white solid being used as the principal precursor for the manufacture of beryllium metal. The production of beryllium is done by the reduction of( BeF_2) at 1300°C with magnesium in a graphite crucible:

A fluorometric method using morin in an alkaline-buffered chelating solution has been developed by the Bureau of Mines for determining beryllium in ores and mill products. Apparatus for measuring fluorescence intensities of the beryllium-morin reaction is described.
Refining Beryllium Ore. With only 0.65 % beryllium oxide (or 4.5 lbs. per ton of beryllium) in the final ore, a process had to be engineered to economically concentrate the beryllium for final processing. The properties that make beryllium useful also make it difficult to extract from its ores.
Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze and spring copper, is a copper alloy with 0.5—3% beryllium and sometimes other elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities.
Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust. Beryllium compounds are commercially mined, and the Beryllium is purified for use in nuclear weapons and reactors, aircraft and space vehicle structures, instruments, x-ray machines, and mirrors.
Beryllium precipitated in fluidconducting fractures from alkaline or near neutral solutions owing to decrease in solubility of flu orine complexes with temperature drop. The forma tion of metasomatic epicarbonate ore is related to the destruction of beryllium fluorocomplexes caused by lowering of F activity due to precipitation of fluorite (CaF 2
Beryllium metal and beryllium-aluminium alloy, beryl ore, beryllium chloride, beryllium chloride, beryllium hydroxide, beryllium sulphate tetrahydrate, and beryllium oxide potentiate the growth of lung tumors in rats exposed by either a single intratracheal instillation or a one-hour inhalation exposure.
the precipitated beryllium hydroxide is further purified by redissolution hydrolysis in sodium hydroxide solution. alternatively, it may be treated with strong and hot concentrated sulfuric acid prior to the precipitation of beryllium values as a hydroxide.
The Element Beryllium Beryllium is a chemical element in the periodic table that has the symbol Be and atomic number 4.

Even though beryllium is extracted from both ores as beryllium sulfate, there are significant differences in the two extraction procedures. For example, the beryl extraction procedure requires five 15-foot diameter thickeners, while the bertrandite process uses eight 9 0-foot diameter thickeners. 8 Bertrandite Ore.
