How do you extract beryllium from its ore?

30.09.2009  Beryllium is extracted from the ore by leaching. The bertrandite ore from Spor mountain can be leached with sulfuric acid. Other ores containing beryl must first be fused or mixed with fluorides. Once the beryllium is in solution it can be precipitated as the hydroxide, and then reduced to beryllium metal in a furnace.
