Indium CRM Alliance

Indium is a very soft ductile and malleable silver metal. It is very abundant in host metals such as zinc lead tin and cooper. Host metals in contrast to minor metals are base metals spread across the globe. Approximately 95 of the refined indium produced in the world comes from the processing of zinc ores.

Gallium Germanium Indium Vanadium Or Molybdenum

 · Abstract A method for the recovery of copper indium gallium and selenium is provided. The method includes steps of using a mixed solution containing a hydrochloric acid and hydrogen peroxide to dissolve the copper indium gallium and selenium. After using the hydrazine to separate the selenium out the copper is reduced by indium metal.

 · of the LED semiconductors contain gallium and/or indium. Both are considered as critical raw materials for the EU implying a significant supply risk in the near future. In this project tribromide ionic liquids (ILs) are proposed for the recovery of gallium and indium from end-of-life LEDs.

Gallium and/or indium separation and concentration method

 · It is possible to recover gallium and indium efficiently and at a low cost from solutions containing traces of gallium and indium. In particular jarosite is produced by performing a specific treatment on a solution obtained by a two-stage neutralization treatment during the zinc leached residue treatment step of wet zinc refining or on another solution containing traces of gallium and indium
