Copper recovery from anode slimes was studied by using sulfate digestion method and recovered by changing pH.D-optimal design was employed for experimental design and analysis of the results. The combined effect of temperature and L/S was investigated and the optimum values of these factors were found to be at a solution L/S of 1.6 and temperature of 211.5 0C that resulted in 93% of the copper recovery while acid addition did not have any significant influence on the recovery of copper. The obtained model is highly significant
