Method for recovery of rare earths from fluorescent lamps. The method comprises six steps. •The individual process steps are : Mechanical separation of coarse components. •Separation of the halophosphate. •Extraction in acids of easily soluble rare-earth fluorescent substances (mainly Y, Eu-oxide) •Extraction in acids of rare-earth fluorescent substances which dissolve with difficulty (for example rare-earth phosphates) •Breakdown of the remaining components which contain rare earths (for example rare-earth-aluminates) •Final treatment.
