Total world reserves of beryllium ore are greater than 400,000 tonnes. Production. The extraction of beryllium from its compounds is a difficult process due to its high affinity for oxygen at elevated temperatures, and its ability to reduce water when its oxide film is removed.
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.

The ore is then transported by 18-wheeler to the processing plant near Delta, Utah, about 50 miles southeast. High-grade ore is mixed with low-grade ore so that all the bertrandite coming to the plant has about the same percentage of beryllium. The final ore has less than .65% beryllium, or about four pounds per ton. Next Post: Refining ...
At its mining site in Delta, Utah, Brush Wellman treats bertrandite ore using a counter-current extraction process to produce beryllium sulfate, BeSO 4. A second route, using the Kjellgren-Sawyer process, treats the beryl ore and provides the same beryllium sulfate intermediate. Th e intermediates

Beryllium was discovered in 1797 as a constituent of the mineral beryl. The metallic form was isolated in 1828 and named beryllium. It was not until 1926, however, that the true value of beryllium was realized. U.S. production of beryllium-copper alloys began in 1932, and in the 1940s, a commercial process was developed to produce beryllium metal.

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).
Large track-mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore-dressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 metres (3,300 feet) below the surface, and tunnels are extended to the ore body.

BERYLLIUM (Data in metric tons of contained beryllium, unless noted) Domestic Production and Use: One company in Utah mined bertrandite ore and recovered beryllium hydroxide from this ore and from imported and domestic beryl. Beryllium hydroxide was shipped to a plant in Ohio, where it was converted into beryllium metal, alloys, and oxide.
Mining and refining of beryllium in the US, which accounts for as much as 90 percent of global production, is dominated by Materion Corp. Formerly known as Brush Wellman Inc., the company operates the Spor Mountain bertrandite mine in Utah and is the world's largest producer and refiner of beryllium metal.
Commercial beryllium ore production in Russia stopped during the 1990s, as did beryllium mining in Argentina, Namibia and Zimbabwe. Materion Brush is the sole US producer of beryllium ore which it mines as bertrandite from a company owned mine in Utah. In China, the Xinjiang Non-ferrous Metal Industry mines beryllium ores.
Kazakhstan, and to China and Japan, for processing into beryllium metal and beryllium alloys. The annual mining and processing capacities are estimated to be 25,000 t/yr of bertrandite ore and 130 t/yr of beryllium hydroxide. Russia, in 2015, announced that it intended to produce beryllium metal on a commercial scale by 2020.
Beryllium Extraction. Only three countries, the United States, China and Kazakhstan, currently process commercially viable quantities of beryllium ores and concentrates into beryllium products. Today, the extraction of beryllium begins with the mining of raw materials (bertrandite ore and/or beryl ore).

A detailed mining operation is employed utilising procedures to follow in survey control, use of cross sections, structure contour maps, and field berylometer. The beryllium ore is mined from selected or predetermined areas of the ore body, placed in the stockpile in layers as blocks on top of each other.
