BERYLLIUM : Beryllium is an extremely toxic metal and if bare to it, at or above the threshold values, it can lead to a chronic beryllium disease or an acute beryllium disease.

Beryllium Extraction and Beneficiation

Beryllium Extraction Process Flowsheet Flotation offers the best means for recovering beryl in concentrate form. Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product. Depressing the feldspar and reflotation of the beryl into a high grade marketable concentrate (at least 8.0% BeO) is

It has several mining properties it has explored in Utah (adjacent to Spor Mountain), Colorado (includes the Boomer Mine – second-largest historical beryllium mine in the US) and also in Brazil (Minas Gerais). Most effort has been expended on the 7,500 acres it staked at Spor Mountain. The last major work there was in 2011 when the company undertook a program that consisted of 35 reverse circulation holes.
