CN100507033C - Method for recovering indium - Google Patents

This invention provides a method for recovering indium which can recover high-purity indium in a simple process at low cost in a short time with high recovery. High-purity indium is recovered by disintegrating an indium-containing material such as an ITO target scrap, then grinding the material to such a level that the proportion of coarse particles having a diameter larger than a ...

diluted indium solution must be concentrated before being sent to a subsequent step such as recovery of the metal by electrowinning. The aim of the present work was to apply solvent extraction using bis(2-ethylhexyl) phosphate (D2EHPA) in order to maximize the indium concentration in the solution. Firstly, the extraction and stripping steps were investigated using

Efficient separation and recovery of gallium and indium in ...

Spent copper indium gallium selenide (CIGS) materials are considered a viable resource for the recovery of Cu, In, Ga, and Se. The oxidative roasting-leaching-extraction separation scheme for the recovery of these valuable metals is proposed. Spent CIGS materials were first roasted to transform Cu, In, and Ga from selenides to oxides and volatilize Se. Hydrochloric acid was
