Two alternative process routes for recovering pure indium from waste liquid crystal display panels
Recovering indium from liquid crystal display (LCD) screen waste is important from a sustainability point of view for several reasons: the environmentally hazardous metals are not landfilled, the recovery process involves ...
Novel mechanical pre-treatment methods for effective indium recovery from end-of-life liquid-crystal display panels
This study investigated the suitability of mechanical pre-treatment methods (mechanical abrasion and treatments of heat, laser, and plasma) together with a hydrometallurgical process comprising leaching and cementation for ...
Recovery of indium from indium tin oxide by solvent extraction
Recovery of indium from LCD screen wastes, which contain indium in the form of indium tin oxide (ITO) as the electrode material, is becoming economically and environmentally justified. Indium is a valuable metal and the ...
