Recovery of indium from the etching solution of indium tin

Jan 18, 2016The etching waste solution from the indium-consuming fabrication processes is considered as the viable resource for indium recovery. The extraction equilibrium of indium(III) from a hydrochloride acid solution using di-(2-ethylhexyl) phosphoric acid (D2EHPA) as an extractant and dissolved in kerosene by solvent extraction was studied.

Recovery of indium from used LCD panel by a time efficient

Mar 01, 2013Highlights In this study, we recovered indium from a waste LCD panel. The ITO glass was milled to obtain micron size particles in a HEBM machine. Effect of particle size of ITO glass on the amount of dissolved In was investigated. In a very short time, a considerable amount of In was recovered. Amount of HCl in acid solution was decreased to 40 vol.%.

Optimization of Indium Recovery and Separation from LCD

Indium tin oxide (ITO) is currently the choice of electrode material in liquid crystal displays (LCDs). D2EHPA is known to be an extractant that can be used to selectively recover indium from 1 M sulfuric acid. In order to optimize the extraction and separation of indium from LCD waste, the effects of pH, temperature, time, and extractant concentration on the distribution ratios of In(III) and
