Beryllium Properties, History, and Appliions

Jun 25, 2019 · 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.
