There are several Youtube videos of workers in businesses that totally dismantle crt tubes for recycling. The phosphor coating is on the inside of the face of the tube and in these videos one of the workers usually uses an industrial vacuum attachment to remove the coating. The crt's are normally cut into by mechanized machinery and the funnel or back part of the crt that contains all of the lead is removed and sorted into a like pile. The unleaded portion of the crt is vacuumed clean of the phosphor coating and the piece of glass is sorted into an "unleaded" pile. There is also a steel internal frame within the crt that is recycled and the metal band is cut or grinded off. Interesting process!!!
