The invention concerns a method, device and computer program product for controlling a material separation process as well as to a material separatin g system. The material separating system (10) comprises units (16, 26) separ ating desired material from undesired material, units (24, 34) measuring pro cess output variables in the material separation process indicative of the d egree of separation between desired and undesired material, a unit (38) esti mating the state of the process by applying the measured output variables an d external constraints for a prediction time interval on a model of the mate rial separation process, a unit (40) optimising an objective function throug h maximising the recovery of the desired material in the separation process, which optimising provides at least one set point value for each input varia ble of the model, and at least one regulating unit (22, 32) regulating the s eparation process by using the set point value.
