Beneficiation and recovery of indium from liquid-crystal ...

The mechanically shredded LCD waste was leached with HCl for recovery of indium. Possible leaching parameters such as; effect of acid concentration, pulp density, temperature and effect of oxidant H2O2 concentration were investigated to identify the best conditions for indium extraction. Indium (76.16×10-3g/L) and tin (10.24×10-3g/L) leaching was achieved at their optimum condition, i.e ...

Recovery of indium from liquid crystal displays ...

10/03/2016  We evaluated the effects of the recovery process described in the present paper by means of the life cycle assessment (LCA). The goal of LCA was to identify the environmental benefits and impacts of leaching and indium cementation, and to compare this management option for waste LCD panels with incineration and landfilling. For the analysis, we simulated a process to recover indium
