Recycling Indium from Scraped Glass of Liquid Crystal Display: Process Optimizing and Mechanism Exploring

摘要: With rapid growth in the use of liquid crystal display (LCD) and increasing concerns for environmental protection as well conservation scarce metals such indium, recycling indium from waste LCDs is becoming a hot issue current society. In this study, leaching process exploration its mechanism were carried out with full consideration potential theory experiments. The optimal parameters controlled at <75 μm sample size, 180 min retention time, 50 °C temperature, H2SO4 agent, 100 g/L initial concentration, 1:1 liquid–solid ratio. samples yields examined necessary analytical techniques including SEM, XRF, EDS, XRD, FTIR, ICP. We also found that could largely modify raw material enhance activation further recovery. All obtained results findings contribute to affording closed-loop susta...
