Uses of Beryllium: An Extremely Light and Very Stiff Metal

Two minerals, bertrandite and beryl, are mined for beryllium, and both are found in association with igneous rocks. All the beryllium currently being mined in the United States comes from the mineral bertrandite. Bertrandite Sources. A complex series of events must take place to concentrate beryllium into bertrandite.

Apr 14, 2010  There are a lot of impurities in the bertrandite ore; some that gave problems early on were the high sodium content, the high uranium content, and the zirconium. The leftover filtrate still has appreciable quantities of uranium, so it is pumped to evaporation ponds, then shipped elsewhere for final uranium processing.
