IMPACT OF SELECTED PARAMETERS ON EXTRACTION OF INDIUM FROM LCD SCREENS

Abstract

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.
