Extracting silver from nitric acid photovoltaic panels

The study aims to evaluate silver recovery from end-of-life photovoltaic panels using nitric acid leaching and precipitation. Optimal parameters for silver solubilization are 55°C and 2. The leaching efficiency and kinetics of ground cake powder in sulfuric acid, ferric sulfate, and thiourea were investigated in the leaching system. In particular, the. . innovations that have brought about cost reductions.
