DISSOLUTION OPTIMIZATION OF COPPER FROM ANODE SLIME IN H2SO4 SOLUTIONS

In the present study, aimed at the extraction of copper and the concen tration of precious metals in anode slime, the optimum process conditi ons were sought for the dissolution anode slime from the Sarkuysan Co. in Turkey. The blade number of the mechanical stirrer, reaction tempe rature, O-2 flow rate, stirring speed, acid concentration, solid-to-li quid ratio, reaction period, and roasting temperature were chosen as p arameters. Using the Taguchi method, the optimum process conditions, a t which 99.67% Cu conversion was reached, were found as follows: blade number 1, reaction temperature 70 degrees C, O-2 flow rate 1.24 x 10( -6) m(3).s(-1), stirring speed 450 rpm, acid concentration 5.43 wt %, solid-to-liquid ratio 0.125 g/mL, reaction period 3600 s, and roasting temperature 300 degrees C.
