By adopting central composite design (CCD) of response surface methodology (RSM), a binary quadratic regression prediction model was established, with roasting temperature and oxygen concentration as influencing factors and copper leaching rate of calcine as the response value. It is shown that the prediction model presents a P value of 0.018 2, adjusted determination coefficient of 0.810 1, and signal-to-noise ratio of 7.323 6, exhibiting favorable reliability and prediction accuracy. Roasting temperature has an extremely significant effect on copper leaching rate, while oxygen concentration brings insignificant effect, and their interaction is weak. The parameters were optimized via Design-Expert software, and the optimal roasting process parameters are obtained as follows:roasting temperature of 750 ℃ and oxygen concentration of 30%. Under such optimized parameters, the predicted copper leaching rate of calcine is 97.47%, while the copper leaching rate of calcine in industrial applications reaches 98.17%.
