Abstract
In this study, we tried to select a slag system capable of pyro-metallurgical process through analysis of sludge generated from PCB plating and etching process solution. Based on this, the possibility of extracting valuable metals in the sludge was studied by experimental and thermodynamic approaches. The sludge was dried at $100{\sim}500^{\circ}C$ and the morphology, chemical composition and phase of the sludge were analyzed. The possibility of pyro-metallurgical process of sludge was investigated through thermodynamic approach using FactSage software.
