In India, beryllium is extracted from beryl ore. In its pure form, beryl ore is a beryllium-aluminium silicate (3BeO.Al 2 O 3.6SiO 2) [6]. Though a large number of methods have been proposed, only two are currently used for beryllium extraction from the ore. These are the sulphate and the fluoride process [6]. In the sulphate process,
