    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 other elements in minerals. Notable gemstones which contain beryllium include beryl (aquamarine, emerald) and chrysoberyl. As a free element

  • Beryllium element extraction– mining technique, melt

    MINING AND PROCESSING: The metal beryllium is mined by its extraction from the beryl ores. It does not occur free in nature. The mining of raw minerals such as bertrandite ore and beryl ore from the Earth's crust and volcanic rocks is required. Apart from beryl, beryllium is found in the mineral bertrandite, has become a major ore of the metal

  • beryllium extraction and how it is processed

    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. Beryl is harder than quartz.

    Deaths from kidney diseases were 1½ times more common in ers who ed at beryllium processing plants than in the general public. We found 30 deaths, but expected 20. This is a rare cause of death, and very few ers are likely to die from it. Since beryllium passes through the kidneys, it is possible that it can damage them.

    Beryllium oxide is an excellent heat conductor, with high strength and hardness, and acts as an electrical insulator in some applications. The United States, one of only three countries that process beryllium ores and concentrates into beryllium products, supplies most of the rest of the world with these products.

    SafetyApplicationsComponentsResourcesFormationPropertiesProductionUsesResearchBeryllium is one of the lightest and stiffest metals, but there was little industrial demand for it until the 1930s and 1940s when the aerospace, defense, and nuclear sectors began using beryllium and its compounds. Beryllium is now classified by the U.S. Department of Defense as a strategic and critical material because it is used in products that are vital to national security.

    Mar 04, 2004· Beryllium is a constituent of about 30 identified minerals, but most are rare. The most common beryllium mineral by far is beryl, 3BeO·Al 2 O 3 ·6SiO 2. This is a hard (Mohs 7.5-8.0), relatively light (spgr 2.75-2.80) found in granitic rocks, pegmatites, mica schists and similar environments, occasionally in huge crystals.

    Beryllium Ores mineral formations that contain beryllium in quantities such that its extraction is feasible at modern technical and economic levels. Beryllium is found in the ores mainly in the form of the minerals themselves, as well as in the form of an isomorphic impurity (usually not more than 5–10 percent) in rock-forming minerals.

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.
