بيت /beryllium extraction beryllium science
Beryllium is most often found in the minerals beryl and bertrandite. It is found in the Earth's crust and mostly in igneous (volcanic) rocks. Most of the world's beryllium is mined and extracted in the United States and Russia with the state of Utah supplying nearly two .

Berylliumcontaining Alloys. Adding beryllium to copper creates an alloy with a great combination of properties including strength, formability and elasticity (or "springiness"). Yet, much of the electrical conductivity of the copper is preserved. Copper beryllium is highly valued in aerospace, automotive, energy exploration and telecommunications applications.
