    The Beryllium Corporation of America, founded by Lester Hofheimer in 1927, was the first commercially producing mining company of beryllium-containing materials. Andre w Gahagan, decided to get into the beryllium industry in 1929 and formed the Beryllium Development Corporation, and later, gained control of the Beryllium Corporation of AmericaBeryllium Extraction and Beneficiation,Most of the production of this mineral in the past has been by hand sorting and cobbing of high grade crystals from pegmatite mining operations. The crystals are hexagonal and may range up to several inches across. Beryllium Extraction Process Flowsheet Flotation offers the best means for recovering beryl in concentrate form.

  • Beryllium Wikipedia

    Beryllium is a chemical element with the symbol Be and atomic number 4. It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays.Within the cores of stars, beryllium is depleted as it is fused into heavier elements. It is a divalent element which occurs naturally only in combination with otherrefining beryllium grinding,beryllium mining and ore processinjg .
