摘要: Abstract Thermal decomposition was used to enrich indium tin oxide (ITO) from waste colour filter glass. The layer destroyed through oxidation, and the ITO separated glass substrate. With increase in temperature time of thermal decomposition, yield concentrate decreased, but recovery enrichment ratio increased. Furthermore, could be effectively enriched at 600 °C 8 min, where yield, were 0.06 %, 98 % 1669, respectively. particle size distribution mainly distributed 0.1–1.3 2.6–42.0 μm, with cumulative percentages 4.33 95.55 Moreover, crystal structure recycled not changed. Substantial poisonous harmful mixed flue gas are produced during decomposition. After condensation adsorption by activated carbon, emission controlled avoid serious pollution atmospheric environment.
