Gallium is used as a raw material for a CIGS solar cell.In the manufacturing process of Hose 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 Wet/Dry Vacuum only which does not require pyrometallurgical treatment.We describe the details of the developed process in this report.
