New technique developed to recycle indium from waste LCD

The highest indium recovery (99.8%) using an acid solution with a pH of 2 was achieved when a relatively high concentration of zinc was used (100 grams per litre, g/L). Overall, the best results for indium recovery were found using a solution with an acidity of pH 3, which led to high recovery of indium even at low concentrations (5 g/L) of zinc.

Zinc Sulfide an overview ScienceDirect Topics

1 Recovery from Zinc Sulfide Concentrates. During roasting of zinc sulfide concentrates in fluidized beds, the flue dust will be enriched in cadmium, indium, and thallium, but the bulk of these metals remain in the calcine. That is why the dust is added to the calcine during processing.

Processing of indium: a review ScienceDirect

Aug 01, 2003· The recovery of indium metal from zinc circuits requires different methodology than other sources containing tin and lead. The literature illustrates the simplified flowsheet at Anaconda’s former operations at the smelter located in Butte, Montana (Felix, 1990).As a historical perspective, Atlantic Richfield Co. (ARCO) bought the holdings of the Anaconda Copper Mining Co. in the 1970s

Cross-current leaching of indium from end-of-life LCD panels

In this simulation, the process of indium recovery was advantageous from an economic and environmental point of view. Indeed, cross-current leaching allowed to concentrate indium, save reagents, and reduce the emission of CO2 (with 10 steps we assessed that the emission of about 90kg CO2-Eq. could be avoided) thanks to the recovery of indium.
