Abstract

Indium is a strategic critical metal in manufacturing indium-tin oxide (ITO) thin films for LCD/LED screens. Nevertheless, indium in Earth’s crust is a rare dispersion with an average abundance of 0.02 ppm, which is difficult to recover from primary ore. Hence, scholars focused on Indium recovery from waste LCD screens using hydrometallurgy technologies, which were always with long process. In this paper, a novel process for the separation and recovery of indium from waste LCD by roasting under an H2-H2O atmosphere is proposed. Under optimal conditions, In2O3 can be reduced selectively to gaseous In2O, and then In2O can be recovered efficiently. The effects of roasting parameters on indium recovery were studied utilizing thermodynamic analysis, XRD, and ICP. The results showed that the indium in waste LCD can be reduced to In2O(g) under the H2-H2O atmosphere at 1100–1200 ℃, the recovery of indium was up to 96.53% with an enrichment ratio of 3700.
