The majority of world beryllium ore production, around 80% in 2004, takes place in the US, as shown in Table 1. Most of the remaining output comes from China, Brazil and more recently Mozambique. Mining of beryllium minerals is also thought to have taken place in Madagascar, Portugal and Zambia but no official production statistics are available.
Beryllium's importance grew dramatically with the Manhattan Project—the secret initiative to construct atomic weapons—and the subsequent growth of the nuclear weapons industry, fueled by the Cold War. This lightweight metal is a vital component of nuclear weapons.
The processing of beryl to produce beryllium metal or the oxide is one of the most difficult tasks in extractive hydrometallurgy. This difficulty arises from the fact that the beryl ore is refractory to almost all chemical leachants including boiling sulfuric acid (Schwenzfeier, Jr., 1955; Engle and Hopkins, 1924).
Refining Beryllium Ore. With only % beryllium oxide (or 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.
In 2006, Mozambique's share of the world's tantalum mine output amounted to 6%; beryllium, 5%; and aluminium, 2%. Beryllium Wikipedia · Beryllium is a chemical element with symbol Be and atomic number 4.
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 to .

Uses of Beryl. Before 1969, beryl served as the only important ore of beryllium metal. Since then, about 80% of the world's supply of beryllium is refined from bertrandite, a beryllium silicate hydroxide, mined at Spor Mountain, Utah.
The total world reserves of beryllium, recoverable by mining, have been estimated to be 200,000 tons (Cunningham 2004). Increasing beryllium contamination of the ecosphere necessitates an understanding of the possible effects of beryllium toxicity on plant growth and development.
