摘要：

Liquid crystal displays (LCD's) are getting increased importance in flows of waste of electric and electronic equipment, for environmental, economic and strategic reasons. This work presents some results of a research carried out on the characterization of the constituting materials and the assessment of feasibility of indium recovery from the LCD-glass component by leaching. Metallic plates, plastics and printed circuit boards are the main components of monitors, and the LCD-glass only represents near 8%. Leaching of indium with low concentrated H2SO4 solutions was successfully attained, which seems to be a good option for its metallurgical recovery.
