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).
