1.2.1. Production. More than 40 beryllium-bearing minerals are known, but only two are of economic significance. The first beryllium mineral to be exploited commercially was beryl (3BeO.Al 2 O3.6SiO 2), an aluminosilicate ().The largest deposits of beryl are found in Brazil and the former USSR (Petkof, 1982; Stonehouse & Zenczak, 1991).Beryl ore contains about 11% …
