The main purpose of this study was to recover the silver and aluminum metals contained in the washing liquid generated at a scrap compact disk recycling plant. Thus, various methods of electric winning, as well as precipitation by NaCl, CaCl, NaS, and HCl, were adopted to recover these two metals from the collected washing liquid. The results revealed that the liquid had concentrations of 3 ppm of silver and 6 ppm of aluminum; therefore, due to such low concentrations, recovery of either of these metals would not be economical. It was also demonstrated that neither the electric winning methods nor precipitation by NaCl, CaCl and NaS can effectively remove the silver and aluminum from the washing liquid. However, the 99.77% silver and 89.41% aluminum contained therein could be removed by using the HCl to adjust the pH to 7.
