Abstract
The effective recovering process that consists of air-jetting, centrifugation and air-classifying was developed for phosphor recycling from flat panel display devices. At the first processing stage of air-jetting, 95% phosphor could be recovered while the recovery rate was dependent on the dimension of CCFLs. After two subsequent stages of mechanical separation, Blue, Red and Green rich phosphor could be selectively collected. The recovery of Red phosphor was 61.2% and purity of (Y, Eu)2O3 was 95%.
Keywords: Air-jetting, phosphor, rare earth element, recovery, waste CCFLs.
