Fundamental study of recycling plasma display panels
A method for the beneficiation of plasma display panels was evaluated from a literature survey, thermodynamic data, and experimental work. The proposed process consists of mechanically breaking the panel, acid baking the powder coated glass, water dissolution of the acid baked product, solvent extraction of indium, and rare earth oxalate precipitation. The benefit of this process is that there is only one feed stream and the need for extra processing equipment is not necessary. A kinetic leach study was conducted on agitated leach tests for ITO powder. The ideal leaching conditions were found ...
