Modeling and control in the mineral processing industries
Résumé
After having rapidly presented the main devices necessary for control in the mineral processing industries, the authors outline the problems encountered when modeling such systems. The model identification is more or less delicate according to whether one considers a knowledge model (ball mill and cell flotation models are given) or a representation model (copper flotation in Pyhäsalmi is given). The principal control modes currently used are proposed as examples (feedforward and feedback control) and some optimizing methods are summarized.
