In this method, we first build the state-space concentration-predictive model and the finenessprediction model based on the weighted multi-model of size-mass balance; and then, we develop an optimal multi-model predictive control scheme for optimizing multiple objectives including the interval control of concentration and fineness of the discharged ore pulp from the ball-mill, along with economic indices. The local optimal control law of the controller is obtained by minimizing a multiplier penalty function. The simulation and the field test results show the effectiveness of this method. %K mineral grinding process %K multiple model predictive control %K multiple objective optimization %K interval control %K multiplier penalty function
