| 简介 | A method for recovery of rare earths from fluorescent lamps includes six steps. Individual steps are : ‧ mechanical separation of coarse fraction. ‧ separation of halophosphate. ‧ extraction of RE-luminescent material (primarily Y, Eu-oxide) that is easily soluble in acids. ‧ extraction of RE-luminescent material (for example, RE-phosphate) that is not easily soluble in acids. ‧ decomposition of residual RE-containing components (for example, RE-aluminate). ‧ final processing. | ||
