<p>A method for processing fluorescent material which removes various impurities contained in fluorescent material recovered in developing a fluorescent coating on a fluorescent screen of a color image receiving tube. The recovered fluorescent material can therefore be reused. The method comprises the steps of recovering unexposed fluorescent material which comes off on being developed, dispersing the recovered fluorescent material in water, cleaning the dispersed fluorescent material with an alkali, draining and washing the resultant fluorescent material in water, dehydrating and drying the fluorescent material, and screen-sizing the dried fluorescent material through mesh. Optionally, the cleaned fluorescent material is surface-treated with a colloidal silica (water glass) solution and zinc hydroxide suspension.</p> |
