Application of response surface methodology for modeling of ball .

Modeling of some parameters of wet ball milling system of copper sulphide ore was performed in this study. A three level Box–Bhenken design combining a response surface methodology (RSM) with quadratic model was employed for modeling of key operating parameters of ball mills. Grinding experiments were designed.
