    Hydrometallurgical methods of indium recovery from obsolete LCD and LED panels
    (2016) Krištofová, Patrícia; Rudnik, Ewa; Miškufová, Andrea
    This paper shows a review of literature data on the possibilities of indium recovery from ITO layers of waste LCD and LED displays. A short characterization of indium, its compounds, resources, production, and applications is presented. The structure and operation of LCD displays are shown. A detailed overview of the ITO leaching process is presented. Methods of indium(III) ion separation from the leachate solutions (SX, HoLLE, IX) as well as recovery of the final products (precipitation, cementation, electrowinning) are also shown.

    Impact of selected parameters on extraction of indium from LCD screens
    (Wydawnictwa AGH, 2017) Stępień, Michał; Palimąka, Piotr Robert; Bukowska, Andżelika
    Due to the minute availability of indium and its crucial importance to the world economy, it is necessary to find alternative sources of this metal. As a large proportion of indium production is consumed for the purpose of LCD screen manufacturing, it seems reasonable to investigate their recycling leading to the recovery of this metal. The present work investigates the impact of time, temperature, and the concentration of sulfuric acid on the effectiveness of indium extraction from milled LCD panel glass scrap originating from portable computers manufactured between 2005 and 2012. The conclusion of our research defines the optimal conditions for extraction.
