Model Predictive Control for Froth Flotation Plants

The optimization horizon should be long enough in order to cover the time constant of the process. Since a flotation circuit is a rather slow process, the sampling time of the controller can be chosen such as to allow enough time in order to perform the computations for solving the optimization problem.
