A brief description of the chain of processes involved in MP plants is first given. Then a general control scheme is proposed and the various ingredients of a control loop are described, illustrating each element or concept by an example.

Model predictive control has been employed to handle the strong coupling multivariable system of grinding circuit. A four-input–four-output model of grinding circuit has been developed for process control. Constrained model predictive control has been evaluated in an iron ore concentrator plant. Compared with the former two-input–two …

The behaviour of mineral processing is a response to the complex interaction of primary rock attributes, such as chemical composition, mineralogy, texture, and fracturing [1,2,3].Therefore, to understand how differences in material attributes impact metallurgical plant performance, novel machine learning (ML) applications could help.
