RECYCLING OF CdTe PHOTOVOLTAIC MODULES: RECOVERY …

cadmium was recovered by electrowinning in solid sheets of purity greater or equal to 99.5%. For manufacturing scrap equivalent to 10 MW/yr spent modules, the total capital and incremental operating cost of the electrowinning process is estimated to be only 0.1 U.S. cents/Wp. Tellurium was also quantitatively recovered by reactive precipitation.

The barren leachate (or raffinate) is sent back to the leaching system. Electrowinning is the recovery of copper from the loaded electrolyte solution produced by solvent extraction, yielding refined copper metal. The copper-poor (or lean) electrolyte from electrowinning is returned to the SX plant.

The electrowinning system consists of an electrowinning process, a Cd (cadmium) distillation process and a TRU drawdown process. The electrowinning process recovers the residual uranium and TRU from the electro-refined LiCl-KCl salt using Cd. The recovered uranium and TRU moves to the liquid cadmium cathode (LCC) through the electrowinning process.
