The estimation of the flotation rate constant is generally considered difficult because of the number of variables – not always measurable – determining its value. Among them, the particle size distribution and hydrodynamic characteristics are co

Modeling of flotation has been the subject of many investigations aiming at better understanding the process behavior per se, and as well for process design, control and optimization purposes. With this regard, the importance of hydrodynamic characte

Even after having been used for several years in mineral processing plants, the full potential of the column flotation process is still not fully exploited. There is obviously more than one reason explaining this, but one important contributing facto

A difficulty with constrained nonlinear control is the minimization of the cost function. With complex system representations such as fundamental models, the required optimization algorithm may be complex to implement, setting its parameters may be d

Two ways to model a process are physical modeling and empirical modeling. Physical models rely on basic laws of physics whereas empirical models are obtained by fitting an empirical equation to experimental data. Empirical models are less complex and

A softsensor was developed to estimate the hydrocyclone overflow dynamic particle size distribution of a grinding circuit using neural network models. Because of the inherent dynamics associated with the grinding process, the time histories of the fo

The aim of this work is the control of hydrodynamic variables of a pilot flotation column working with a three-phase system (air-water-ore) in an industrial environment. Since hydrodynamic variables are closely related to metallurgical and economical

This paper presents the results of the application of a new process control technique, the Learning Control, to a mineral processing operation. A hierarchical system of learning automata is used as a model of the controller. An empirical simulator ca

Since their first commercial application for mineral separation in the early 1980s, flotation columns have become a standard piece of equipment in mineral concentrators particularly for cleaning operations. This chapter presents and discusses the mos
