What Is the Mineral Beryl Used For? | Sciencing
Scientific Uses of Beryl. Beryl contains a very rare element called beryllium, which is only found in about 100 minerals. That makes it very significant to the scientific community, although they have also used beryl in a few other applications. One of the most common is the production of wire, although beryl has also been used on space shuttles.

Sources of Beryllium Metal and Extraction Locations
Today, the extraction of beryllium begins with the mining of raw materials (bertrandite ore and/or beryl ore). Beryl ore is melted in industrial furnaces, solidified and crushed, then treated with sulfuric acid to produce a water-soluble sulfate. Bertrandite ore is crushed, made into slurry and treated with sulfuric acid to form a sulfate.

Hehe, thanks. I'm familiar with the chemical difference, but I was thinking it might be a bit like lead or mercury (that is, a variety of compounds being similarly toxic to the native metal when ingested), and I did read some reports of chronic beryllium poisoning in beryllium mines (where I assume the major ore would be beryl).
