Extraction equilibrium of beryllium and aluminum and recovery of beryllium from Egyptian beryl solution using CYANEX 921

Based on the obtained results, separation of beryllium from aluminum and recovery of pure beryllium from beryl mineral were studied. Removal of iron as the main interfering ion in the beryl solution was investigated. A flow chart for the Be/Al separation process was developed and applied to recover pure Be(II) from Egyptian beryl.
