Recovery of valuable components from spent phosphors from WEEE by solvent extraction is described. Concentrate of phosphors from CRT displays or compact fluorescent lamps is leached by nitric acid and yttrium and europium are isolated by DEHPA extraction. Mercury is then precipitated from the raffinate
