Grinding circuits are used in most mineral processing plants. Their widespread application makes the efficient running of the circuits essential to almost all resource projects. This paper will show that, with the application of modern multivariable control techniques, improved plant performance can be obtained when compared with conventional single loop control strategies.
Grinding mill circuits are the most energy and cost intensive unit processes in the mineral processing industry and therefore the study of the control systems for grinding circuits remains important (Ramasamy et al., 2005, Wills and NapierMunn, 2006).Grinding circuit control objectives range from maintaining system stability to achieving maximum economic benefit.

Grinding circuit (GC) of mineral processing industry is characterized by its multivariable, high interacting, timevarying parameters and large measurement delay nature. The product particle size and the circulating load of the GC are two important production indexes that directly related to performances of the subsequent beneficiation process and production rates of the overall mineral
In this case, the primary grinding stage in a concentrator comprises a rod mill in open circuit and a semiautogeneous mill in closed, circuit with a hydrocyclone classifier.

By using neural networks and multivariable predictive control schemes, these mills can grind ore to a smaller range of sizes and reduce their overall power consumption, increasing recovery and reducing power costs. SmartGrind can reduce the standard deviation of the ore size range by 50%, increasing recovery significantly.
