A BeO content of 10 percent is considered necessary for the economic extraction of beryllium fr om beryl and bertrandite ores. However, bertrandite ores are still considered a commerci ally viable source of beryllium because of the large reserves present, open-pit mining, and the fact that beryllium may be extracted by leaching with sulfuric acid.

By the end of 1969, the plant was producing its first beryllium hydroxide concentrate. Process for Refining Bertrandite Ore. The solvent extraction process removes the beryllium by first crushing and wet grinding the ore in a ball mill, then leaching it with sulfuric acid and steam in rotating tanks at 95 ° C to dissolve the beryllium.
Beryllium Ore - Business Advisory Network
Beryllium is extracted from two types of ores; beryl (Be 3 Al 2 (SiO 3) 6) and bertrandite (Be 4 Si 2 O 7 (OH) 2). While Beryl generally has a higher beryllium content (three to five percent by weight), it is more difficult to refine than bertrandite, which on average contains less than 1.5 percent beryllium.

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 ...
Selective extraction of uranium from uranium–beryllium ore ...
Uranium was selectively extracted from uranium–beryllium ore by a facile acid leaching process. Sulfuric acid is very efficient in selective extraction of U from low grade U–Be ore. Experimental results indicate that leaching process carried out by 0.2 M sulfuric acid at 348.5 K for 50 min with the solid–liquid ratio of 0.25 g/mL helps to ...
