Gallium is used as a raw material SANDALS for a CIGS solar cell.In the manufacturing process of CIGS solar cells, only 30% of the target material is used, and the rest is not used and becomes a spent target scrap.In order to recover gallium from spent target scrap, we investigated the process composed of hydrometallurgical treatment only Gremlins which does not require pyrometallurgical treatment.

We describe the details of the developed process in this report.
