Beryllium Copper Overview. Copper beryllium alloys are used for their high strength and good electrical and thermal conductivities. There are two groups of copper beryllium alloys, high strength alloys and high conductivity alloys. The wrought high strength alloys contain 1.6 to 2.0% beryllium and approximately 0.3% cobalt.

Pegmatites of the Black Hills, South Dakota. For the pegmatite collector, the Black Hills may be paradise. Within its borders, thousands of pegmatites occur. In fact, pegmatite dikes crisscross Mount Rushmore. Cleophas C. O'Harra (1902) called this the "Mineral Wealth of the Black Hills".

beryllium, is the principal beryllium mineral mined in the rest of the world; beryl ore typically contains from 2 to 4 weight percent beryllium. Countries with active industrial beryl mining operations include Brazil, China, Madagascar, Mozambique, Nigeria, Portugal, and Rwanda. From a historical perspective, Argentina, India, and

The Topaz Mountain Beryllium Mine is in Juab, Utah. Historically the site has been part of the Spor Mountain-Topaz Mountain Mining District. The site was first discovered in 1959. The Topaz Mountain Beryllium Mine is a surface mining operation. Initial production took place in 1969 and overall output was considered to be medium size.

Beryllium copper is an alloy comprising of copper as the base and 0.5 to 3 % of beryllium. In some cases, other alloying elements like nickel or cobalt are also used . The alloy has a huge demand in innumerable industries due to its high strength in adjunct with non-magnetic and non-sparking properties.

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 is highly sensitizing, even at very low levels of exposure. Exposure can cause acute beryllium disease (ABD) and chronic beryllium disease (CBD). ABD is a condition that resembles pneumonia. It can occur after short-term, high levels of exposure to beryllium (>1 mg/m 3). CBD is an inflammatory lung disease that causes fibrosis.

Today, the extraction of beryllium begins with the mining of raw materials (bertrandite ore and/or beryl ore). Beryl ore is melted in industrial furnaces, solidified and crushed, then treated with sulfuric acid to produce a water-soluble sulfate. Bertrandite ore is crushed, made into slurry and treated with sulfuric acid to form a sulfate.
