Model of Stabilization of the Quality of Iron-Ore Concentrate in the Process of Magnetic Separation with the Use of Extreme Regulation

Resumo

In the present paper, we reflect the main aim of control over the process of separation of iron ore in the course of wet magnetic dressing. We propose a procedure of deducing equations for the dependence of losses of the useful component in tailings and the mass fraction of magnetite iron in the concentrate on the water flow rate in the separator and the rotational speed of its drum. A mathematical description of some blocks of the automatic system of control over the magnetic separator is given. The results of its modeling in the package of applied programs of the MATLAB Simulink software are presented. The operation of the system is studied under the conditions of drift of the static characteristics of the magnetic separator.
