This study aims to design a commercial process to leaching copper from electronic waste. The proposed leaching process has been sub-divided into two stages 1 physical separation 2 metal recoveries. Stage 1 involve s size reeducation to 3-4 mm, stage 2 involves the dissolution of metals in acid in different operating condition (time, temperature, concentration of acid, weight of sample). Copper leaching and its affecting factors have been studied statistically. Statistical analysis of the data showed that the most influential factor on the process of leaching process are weight, concentration H2O2and Temperature, finally the results of experimental runs for the leaching of copper from the computer circuit boards shown High recovers for copper (>%80( Under suitable condition of weight 83.1 gm,concentration of H2O2 (0.86 gm/ l ) and temperature 100 OC in 0.5 hr.
