Two　methods,　direct　acid　leaching,　alkali　fusion　and　acid　leaching,　were　adopted　to　deal　with　the　Waste　Trichromatic　Fluorescent　Phosphors　(WTFPs).　The　research　results　showed　that　using　the　direct　acid　leaching　method　can　only　dissolved　the　Red　phosphors.　And　yet,　high-temperature　alkali　fusion　could　effectively　destroy　the　Mg-Al　spinel　structure　of　the　components　of　the　Blue　and　the　Green　phosphors,　and　make　REEs　dissolved　completely.　The　acid　leaching　efficiency　of　REEs　could　reach　100%　when　the　weight　ratio　of　NaOH　with　WTFPs　is　6:1,　and　the　calcination　temperature　is　900　degrees　C　and　the　reaction　time　is　4　hrs.
