In the past few decades, cathode ray tube (CRT) is widely equipped in TV and computer devices as an important part of monitors. However, in recent years, due to the rapid development of monitor technology, CRT is replaced by liquid crystal display (LCD) gradually. Therefore, amounts of waste CRT is increasing sharply around the world. CRT consists of leaded glass which belongs to hazardous waste. Lead is one kind of metal, which is harmful to human health. So the disposal and treatment of leaded glass have become one of the hotspots and difficulties in the disposal field of e-waste. Due to the stability of lead wrapped in glass matrix, the lead separation from glass is hard. At present, there is no effective way to deal with leaded glass. However, a variety of new methods have been studied in laboratory, and good effects have been gained. Several advanced methods such as high temperature separation and pretreatment +hydrometallurgical leaching are introduced in this paper. (C) 2016 The Authors. Published by Elsevier B.V.
