This technique is well known for its efficiency and versatility in produce clean concentrates. The present work can be divided in three parts. The first one, composed by chapters one to three, presents a brief survey on system modeling, column flotation and nonlinear system identification. The last part, composed by chapters five, six and appendix A, presents the main results obtained by applying identification techniques to the pilot plant. In chapter five and appendix A the dynamical testing of the plant is described as well as the best identified models.
Inputs are the signal that controls the tailing flow pumps, wash water flow and air flow.
The model outputs are the pressure values at the measuring points in the collection zone. The main conclusions are presented in chapter six.
