In the present study, aimed at the extraction of copper and the concentration of precious metalsin anode slime, the optimum process conditions were sought for the dissolution anode slimefrom the Sarkuysan Co. in Turkey. The blade number of the mechanical stirrer, reactiontemperature, O2 flow rate, stirring speed, acid concentration, solid-to-liquid ratio, reaction period,and roasting temperature were chosen as parameters. Using the Taguchi method, the optimumprocess conditions, at which 99.67% Cu conversion was reached, were found as follows: bladenumber 1, reaction temperature 70 
C, O2 flow rate 1.24 × 10-6 m3·s-1, stirring speed 450 rpm,acid concentration 5.43 wt %, solid-to-liquid ratio 0.125 g/mL, reaction period 3600 s, and roastingtemperature 300 C.
